Of the OSP host complex <figref>480</figref> also includes a proxy server <figref>4806</figref> to the Directing data requirements and / or other enabling of communication between the client system <figref>405</figref> and the Internet <figref>465</figref>, The proxy server<figref>4802</figref> can a IP tunnel ( "Internet Protocol ") to convert data from the OSP protocol in the standard Internet protocol and transmitting the data to the Internet <figref>465</figref> contain. The IP tunnel also converted of the Internet in the standard Internet protocol data received back in the OSP protocol and sends the converted data to the routing processor <figref>4802</figref> to surrender back to the client system <figref>405</figref>,

Of the Proxy server <figref>4806</figref> may authorize that the client system <figref>405</figref> Standard Internet protocols and formatting for access to the OSP host complex <figref>480</figref> and the Internet <figref>465</figref> used. For example, the participants an OSP TV client application with an on the client system <figref>405</figref> installed Use embedded browser application, a requirement in the standard Internet Protocol such as HTTP ( "Hypertext Transport Protocol ") to create. In a packet-based implementation, the Data packets within a standard Internet tunneling protocol, such as, for example, UDP ( "User Datagram Protocol "), be encapsulated and to the proxy server <figref>4806</figref> be steered. The proxy server <figref>4806</figref> can an L2TP tunnel ( "Layer Two Tunneling Protocol") contain the a PPP session (point-to-point protocol) with the client system <figref>405</figref> establish can.

Of the Proxy server <figref>4806</figref> can also act as a buffer between the Client system <figref>405</figref> and the Internet <figref>465</figref> serve and can content filtering and time-saving techniques to deploy. For example, the proxy server <figref>4806</figref> Parental Controls the client system <figref>405</figref> check and Content from the Internet <figref>465</figref> in accordance with the Parental Control settings Request and transmitted. In addition, the proxy server <figref>4806</figref> one or more caches to store containing information on frequently accessed. If it is determined that the requested data is stored in the cache, the proxy server <figref>4806</figref> the information from the cache to the client system <figref>405</figref> Send and the need for Access to the Internet <figref>465</figref> avoid.

In particular, have the client system<figref>505</figref> and the communications link <figref>515</figref> in rule attributes that are comparable to those with respect to the Client Systems <figref>105</figref>. <figref>205</figref>. <figref>305</figref> and <figref>405</figref> and communication routes <figref>115</figref>. <figref>215</figref>. <figref>315</figref> and <figref>415</figref> from <figref idrefs="S38">1</figref>-<figref idrefs="S41">4</figref> described are. equally the host system can <figref>510</figref> from <figref idrefs="S42">5</figref> attributes possess the potential with a embodiment the in <figref idrefs="S38">1</figref>-<figref idrefs="S41">4</figref> each described host systems &lt;?page 8?&gt;<figref>110</figref>. <figref>210</figref>. <figref>310</figref> and <figref>410</figref> comparable are, and illustrates this. <figref idrefs="S42">5</figref> describes However, an embodiment of host system <figref>510</figref>Wherein primarily to a certain Implementation of the IM host complex <figref>590</figref> is focused. For purposes of communicating with the IM host complex <figref>590</figref> the transfer network <figref>560</figref> in the Generally a telephone network.

the Client system <figref>505</figref> contains a client device <figref>520</figref> and a client controller <figref>525</figref>, Of the Client controller <figref>525</figref> is generally for manufacturing a connection to the host system <figref>510</figref> including the OSP host complex <figref>580</figref>, The IM host complex <figref>590</figref> and / or Internet <figref>565</figref> in a position. In one implementation, the client controller includes<figref>525</figref> a IM application for communicating with servers in the IM host complex <figref>590</figref> among Using exclusive IM protocols. The client controller<figref>525</figref> can also applications such as as an OSP client application and / or an Internet browser application for communicating with the OSP host complex <figref>580</figref> or the Internet <figref>565</figref> contain.

the Host system <figref>510</figref> contains a host device <figref>535</figref> and a host controller <figref>540</figref>, The host controller <figref>540</figref> is generally to transmit instructions to any or all of the elements of the host device <figref>535</figref> in the situation. For example, contains in one implementation, the host controller <figref>540</figref> a or more, to one or more elements of the host device <figref>535</figref> charged Software applications. In other implementations, however, as above described, the host controller <figref>540</figref> any included several other programs, machinery and equipment, the independent or work collectively to the host device <figref>535</figref> to control.

the Host system <figref>510</figref> contains a login server <figref>570</figref>Which for enabling communications with and authorize access by client systems <figref>505</figref> to different elements of the host system <figref>510</figref> including an OSP host complex <figref>580</figref> and an IM host complex <figref>590</figref> be able to. The login server<figref>570</figref> can a implement or more authorization procedures to simultaneous Access to the OSP host complex <figref>580</figref> and the IM host complex <figref>590</figref> to enable. The OSP host complex<figref>580</figref> and the IM host complex <figref>590</figref> are through one or more OSP host complex gateways <figref>585</figref> and one or more IM host complex gateways <figref>595</figref> connected. Each OSP host complex gateway <figref>585</figref> and IM host complex gateway <figref>595</figref> can all Protocol conversions perform, that are required to enable communication between the OSP host complex <figref>580</figref>. the IM host complex <figref>590</figref> and the Internet <figref>565</figref> to enable.

Around to start an instant messaging session on the IM host complex <figref>590</figref> access, represents the client system <figref>505</figref> a link to the login server <figref>570</figref> ago. The login server <figref>570</figref> usually determines whether the respective Participants to access the IM host complex <figref>590</figref> is authorized, by verifying an ID and a password of the participant. If the subscriber to access the IM host complex <figref>590</figref> authorized is used by the login server <figref>570</figref> a hashing technique to the screen name of the user to a specific IM server <figref>5902</figref> to Use during the to identify the subscriber session. The login server<figref>570</figref> passes the client system <figref>505</figref> the IP address of the particular IM server <figref>5902</figref>. gives the client system <figref>505</figref> an encrypted key (d. h., a cookie) and interrupts the connection. The client system<figref>505</figref> used then the IP address to connect to the respective IM server <figref>5902</figref> through the communication link <figref>515</figref> and receives Access to this IM server <figref>5902</figref> using the encrypted key. In Usually the client system <figref>505</figref> with a Winsock API ( "Application Programming Interface ") equipped be it the client system <figref>505</figref> enables an open TCP connection to the IM server <figref>5902</figref> produce.

After this a connection to the IM server <figref>5902</figref> been prepared is, the client system can <figref>505</figref> Data directly or indirectly to the IM server <figref>5902</figref> and one or more associated Domain servers <figref>5904</figref> transfer or access content thereof. The IM server<figref>5902</figref> supports fundamental instant messaging services, and the domain server <figref>5904</figref> can associate support services, such as, for example, administrative issues, directory services, Chat and stakeholders. The purpose of the Domain Server<figref>5904</figref> consists generally therein that the IM server <figref>5902</figref> imposed reduce load by adopting of responsibility for some of the services within the IM host complex <figref>590</figref>, By accessing to the IM server <figref>5902</figref> and / or the domain server <figref>5904</figref> can a subscriber use the IM client application to see if certain participants ( "buddies") are online, instant messages Replace with certain participants, participate in group chat rooms, Files such as photos, invitations or documents act, other participants with similar Interests to find out customized news and stock quotes receive and browse the Web.

at the implementation of <figref idrefs="S42">5</figref> the IM server <figref>5902</figref> directly or indirectly to a routing gateway <figref>5906</figref> connected. The routing gateway <figref>5906</figref> allows the connection between the IM server <figref>5902</figref> and one or more multiplexors Rufmeldungs- <figref>5908</figref>. by at&lt;?page 9?&gt;example as a route minimizing tool or a Hub is used to connect multiple IM servers to multiple Rufmeldungs-multiplexers. In general maintains an alert multiplexor <figref>5908</figref> a record paging messages and participants that are registered to the paging messages to recieve.

After this the client system <figref>505</figref> to the alert multiplexor <figref>5908</figref> affiliated is a participant may opt for one or more types of paging messages to register and / or receive. The communication path between the client system<figref>505</figref> and the alert multiplexor <figref>5908</figref> is by using another hashing technique to the IM server <figref>5902</figref> destined to the particular alert multiplexor <figref>5908</figref> to identify, the for the session of the subscriber is to be used. After the certain multiplexor <figref>5908</figref> has been identified, passes the IM server <figref>5902</figref> the Client system <figref>505</figref> the IP address of the respective Rufmeldungs-multiplexer <figref>5908</figref> and gives the client system <figref>505</figref> an encrypted key (Ie a cookie). The client system<figref>505</figref> then used the IP address for connecting to the respective alert multiplexor <figref>5908</figref> by the communications link <figref>515</figref> and receives using the encrypted key Access to the alert multiplexor <figref>5908</figref>,

Of the Alert multiplexor <figref>5908</figref> is a Rufmeldungs ​​gate <figref>5910</figref> connected, which, like the IM host complex gateway <figref>595</figref> is capable of the perform the necessary protocol conversions, to build a bridge to the OSP host complex <figref>580</figref> to form. The Rufmeldungs ​​gate<figref>5910</figref> is the interface between the IM host complex <figref>590</figref> and the physical Servers such as servers in the OSP host complex <figref>580</figref>Where state changes occur. In general, the information regarding state changes are and collected from the IM host complex <figref>590</figref> used. Of the Alert multiplexor <figref>5908</figref> however, even with the OSP host complex <figref>580</figref> by the IM gateway <figref>595</figref> communicate, by way of example, to the Servers and subscribers of the OSP host complex <figref>580</figref> certain Information from the gate Rufmeldungs <figref>5910</figref> collected were to pass.

the Rufmeldungs ​​gate <figref>5910</figref> can Rufmeldungseinspeisung accordingly detect a particular type of alerting message. the Rufmeldungs ​​gate <figref>5910</figref> may be a code section containing (Rufmeldungsempfangscode) which is capable of with another code part (Rufmeldungsrundsendecode) on the physical server, where a state change occurs to interact. In general, the on-gate Rufmeldungs <figref>5910</figref> installed Rufmeldungsempfangscode installed on the physical server Rufmeldungsrundsendecode to, upon the occurrence of a particular change in condition a Rufmeldungseinspeisung to the Rufmeldungs ​​gate <figref>5910</figref> to send. contacted After detecting a Rufmeldungseinspeisung the Rufmeldungs ​​gate <figref>5910</figref> the alert multiplexor <figref>5908</figref>. in turn, the client system <figref>505</figref> about the detected Rufmeldungseinspeisung informed.

In the implementation of <figref idrefs="S42">5</figref> contains the IM host complex <figref>590</figref> also one to a database <figref>5914</figref> connected subscriber profile server <figref>5912</figref> to the Save big Amounts of subscriber profile data. The subscriber profile server<figref>5912</figref> can be used to enter subscriber profile data, retrieve, to edit, manipulate or otherwise process. at an implementation include the profile data of a subscriber, for example, the buddy list the subscriber Rufmeldungspräferenzen, Marked shares, identified interests and geographical Place. The participant can enter profile data, edit and / or delete, wherein it to interact with the subscriber profile server <figref>5912</figref> a installed in the client application on the client system <figref>505</figref> used.

Because the data of the subscriber in the IM host complex <figref>590</figref> saved are, the participants need such information for the case, that the subscriber using a new or different client system <figref>505</figref> on the IM host complex <figref>590</figref> accesses, not to re-enter or update. If a participant in the IM host complex<figref>590</figref> accesses, , the IM server <figref>5902</figref> the subscriber profile server <figref>5912</figref> correspondingly instruct the profile data of the subscriber from the database <figref>5914</figref> retrieve and for example, the buddy list of the user to the IM server <figref>5902</figref> and the Rufmeldungspräferenzen the subscriber to the alert multiplexor <figref>5908</figref> to hand over. The subscriber profile server <figref>5912</figref> can also with other Servers in the OSP host complex <figref>590</figref> communicate, to subscriber profile data to share with other services. alternative can User profile data locally on the client device <figref>505</figref> secured will.

Among with reference to <figref idrefs="S43">6</figref> interact a transmitter <figref>602a</figref>. a receiver <figref>602b</figref> and a host <figref>604</figref> according to a procedure <figref>600</figref>In order to transfer audio data. The procedure<figref>600</figref> can by any suitable type of hardware, software, equipment, Computer, computer system, device, Component, program, application, code, storage medium or spread Signal are implemented.

Examples each element of <figref idrefs="S43">6</figref> are described above with reference on <figref idrefs="S38">1</figref>-<figref idrefs="S42">5</figref> generally described. especially hold the transmitter &lt;?page 10?&gt;<figref>602a</figref> and the receiver <figref>602b</figref> usually Attributes which are comparable to those with respect to the client devices <figref>120</figref>. <figref>220</figref>. <figref>320</figref>. <figref>420</figref> and <figref>520</figref> and or Client controller <figref>125</figref>. <figref>225</figref>. <figref>325</figref>. <figref>425</figref> and <figref>525</figref> described are. The host<figref>604</figref> generally possesses attributes that those are comparable, the relative the host devices <figref>135</figref>. <figref>235</figref>. <figref>335</figref>. <figref>435</figref> and <figref>535</figref> and or Host controller <figref>140</figref>. <figref>240</figref>. <figref>340</figref>. <figref>440</figref> and <figref>540</figref> described are. The transmitter<figref>602a</figref>, recipient <figref>602b</figref> and or the host <figref>604</figref> can directly or indirectly, by a known or described handover power be connected together.

Of the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> each associated with a subscriber. To allow file transfers, sets each participant certain preferences for allowing the transfer of Files to and from other participants. For example, the Transmitter and receiver screen name identify participants who have been authorized to them send files or retrieve files from them. Typically each participant will be presented a graphical user interface, a selection permitted under various transfer preferences. The transfer preferences a participant may locally on the client or remotely on the host <figref>604</figref> to be cared for.

in the Generally communicate the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> over a open connection, such as an open TCP connection, by the host <figref>604</figref> is prepared. Usually contain the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> each a Winsock API for manufacturing an open TCP connection to the host <figref>604</figref> and a client application for accessing the host <figref>604</figref>, The transmitter <figref>602a</figref> and the receiver <figref>602b</figref> be at the host <figref>604</figref> connected to establish the connection.

Of the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> communicate via the Connection with the host <figref>604</figref> and with each other. The connection remains during Time in which the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> on the host <figref>604</figref> access, open. In order to the host<figref>604</figref> access, Send the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> each a separate request to the host <figref>604</figref>, The request identifying the associated subscriber using a unique Screen name against the host <figref>604</figref> and against other participants. The host<figref>604</figref> verified subscriber information (Z. B. screen name and password) based on a subscriber database Data stored. If the subscriber information verified is authorized, the host <figref>604</figref> the access. If the subscriber information is not verified, the host refused <figref>604</figref> the access and sends an error message.

at Access to the host <figref>604</figref> the subscriber is a "buddy list" is displayed. General is the buddy list of a user a user interface, the online status and skills of opposite to the participants identified certain screen name, ie "Buddies" lists. especially inform the host <figref>604</figref> the transmitter whether identified Buddies are online, that is currently on the host <figref>604</figref> access. The host<figref>604</figref> also informed a possible participant that identifies the sender as a Buddy has, that the transmitter currently line. allows the buddy list also an instant messaging communication between users. A participant can be a pre-addressed to a buddy instant messaging user interface simply by clicking on the screen name of a buddy on the buddy list activate. If the receiver no "Buddy" is, must be the first Users activate an empty instant messaging user interface and then the instant message to the screen name of the intended receiver address. Optionally, a subscriber to screen names an intended recipient check using the email address of the intended recipient.

In addition to the exchanging instant messages with online buddies can participating stations in group chat rooms, other participants with similar find interests, customized news and stock prices receive, search the web and files to and from other participants transfer. In one implementation, a transmitter interact<figref>602a</figref>. a receiver <figref>602b</figref> and a host <figref>604</figref> according to a procedure <figref>600</figref>In order to transfer audio data.

Of the Transfer of audio data extends the functionality of instant messaging, by the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> Partner-to-Partner on Audio can communicate, ie Microphone and speaker. When the initiates mentation of The process transmitter <figref>600</figref> by designating one or more receiver for Receiving an instant message (eg. As a text message). If the intended recipients "buddies" of the transmitter <figref>602a</figref> are, the transmitter can <figref>602a</figref> the online status and capabilities each recipient before sending the video message by looking at the "buddy list" to confirm. After a Participant has written an instant message and a SEND button clicked, the instant message from the sender is <figref>602a</figref> to the host sent (step <figref>605</figref>).

After receiving the instant message from the transmitter <figref>602a</figref> authenticated the host <figref>604</figref> the instant message (step <figref>610</figref>). additionally to the body of , the Instant Message Header information or the message type, the screen name and / IP address of the sender and receiver &lt;?page 11?&gt;identify, and a randomly Security number generated contain. The instant message, for example, be authenticated by a reverse lookup table to the screen names and / or IP addresses with those of eligible entries match. If either the transmitter<figref>602a</figref> or the receiver <figref>602b</figref> not with a valid Participants associated, the host reports <figref>604</figref> an error message.

After this the instant message is verified, determine the host <figref>604</figref> the Skills Recipient (Step <figref>615</figref>). For example, the host<figref>604</figref> the Online status, the client version and the furnishing of all monitor and update connected devices in real time. The ability to Receiving audio data can of hardware (for example, furnishing such.) Software (z. B. client version) and / or transfer preferences (Z. B. blocked screen name) depend. This talk is possible have to both the speech software and the audio device available. The host<figref>604</figref> reports then the skills Recipient to the transmitter (step <figref>620</figref>).

at Receiving the report from the host <figref>604</figref> shows the transmitter <figref>602a</figref> a UI according to the capabilities the transmitter and / or receiver <figref>702b</figref> (step <figref>625</figref>). If the sender <figref>602a</figref> not speaking is possible then a standard instant messaging user interface is displayed. If speaking at the transmitter <figref>602a</figref> is made possible, but speaking not the recipient <figref>602b</figref> is provided, A START TALK UI with a grayed START TALK button displayed. When speaking both for the transmitter<figref>602a</figref> as well as the recipient <figref>602b</figref> is provided, A START TALK UI with a functioning START TALK button displayed.

Of the process <figref>600</figref> proceeds so that the host <figref>604</figref> the Instant message to the recipient <figref>602b</figref> sends (Step <figref>630</figref>). Recipient<figref>602b</figref> accepted the initial Text message from the host <figref>604</figref> (Step <figref>635</figref>) and shows a UI according to the capabilities the transmitter <figref>602a</figref> and / or of the receiver <figref>602b</figref> (step <figref>640</figref>). When speaking for the recipient <figref>602b</figref> not allows is, then a standard instant messaging UI is displayed. If that Speaking for the recipient <figref>602b</figref> is made possible, but not for the transmitter <figref>602a</figref>, An instant messaging UI with a grayed START TALK button displayed. When speaking both for the recipient<figref>602b</figref> as well as the transmitter <figref>602a</figref> allows is, is an instant messaging UI with a functioning START TALK button displayed.

If speaking for allows both sides is, is both at the transmitter <figref>602a</figref> and at the receiver <figref>602b</figref> a START TALK UI displayed. If the START TALK UI is displayed, a user can a talk session initiate. In one implementation initiated the transmitter <figref>602a</figref> a talk session by sending a call request to the host <figref>604</figref> (Step <figref>645</figref>). The call request may contain information that, among other things, the message type, the screen name and / or IP address of the sender and the receiver and a randomly Security number generated contains. When the transmitter <figref>602a</figref> the START TALK UI clicking, goes START TALK UI about in an END TALK UI.

at Receiving the call request is authenticated, the host <figref>604</figref> the Call request from the transmitter <figref>602a</figref> (Step <figref>650</figref>). The host <figref>604</figref> can authenticate the call request, for example by using a reverse lookup is to the screen names and / or IP addresses with those of valid subscribers match. If either the transmitter<figref>602a</figref> or the receiver <figref>602b</figref> not with a valid Participants associated, the host reports <figref>604</figref> an error message.

After verifying the call request sent by the host <figref>604</figref> the Call request to the recipient <figref>602b</figref> (Step <figref>655</figref>). Upon receipt of the call request which passes through the receiver <figref>602b</figref> Displaying START TALK UI in a CONNECT UI (step <figref>660</figref>). The CONNECT UI informs the recipient <figref>602b</figref>, that the transmitter <figref>602a</figref> a talk session (their wants. At this point, recipient <figref>602b</figref> the Ignore call request, accept the call request or the instant message session schedule.

If recipient <figref>602b</figref> the Call request by clicking on the CONNECT UI accepted (Step <figref>665</figref>) is the CONNECT UI through in the END TALK UI and the host <figref>604</figref> provides a talk session forth (step <figref>670</figref>). If a talk session is active, can speaking users together. At this point, both by the transmitter <figref>602a</figref> and the receiver <figref>602b</figref> END TALK UI displayed. The opening session (steps<figref>675a</figref>b) remains remains active until one of the users END TALK UI clicks. After this a the user clicks the END TALK UI, show both the transmitter <figref>602a</figref> as and the receiver <figref>602b</figref> the START TALK UI, whereby both sides can initiate another talk session.

If the transmitter <figref>602a</figref> the opening session terminates before recipient connects, makes CONNECT UI at the receiver <figref>602b</figref> a transition back to START TALK UI. If both users simultaneously START TALK UI click to ignore the host of a START TALK clicks, so &lt;?page 12?&gt;that a user the END TALK UI and the other the CONNECT UI displays. When the transmitter the START TALK UI clicks before the receiver <figref>602b</figref> the initial Text message accepted, showing the recipient <figref>602b</figref> not the START TALK UI to, but instead displays instantly CONNECT UI at.

at an implementation provides a talk tool an active voice session ago, and it uses three communication channels: a GSI Channel (Generic Signaling Interface), a control channel and an audio channel. The talk tool uses the GSI channel for making the initial Connection. While this compound are exchanged local IP addresses. After the initial Compound phase is done, the GSI channel is no longer used. By using the GSI channel of exchange of local IP addresses is done only if both users allow such exchanges, d. h. by clicking the CONNECT UI. Through these actions, users are previously protected, that their local IP addresses automatically without their consent are obtained.

Of the Control channel is a TCP / IP socket for which the IP address and the obtained port number of the remote site through the GSI channel. The control channel is used to control the attributes of the talk session Send / receive while the session is active. For example, try the talk tool because some firewalls no external connection to a socket on the Inside the firewall allow a connection from both sides of the session. This action allows a connection is established when within the compound at most there is a firewall. If a firewall exists on both sides, is the probability that no connection can be made can and talk session is unsuccessful. To two firewalls to work, the user needs the port range used by the Talk obtained, so that one of the firewalls can be modified to the range can pass through the firewall.

Of the Audio channel is a TCP / IP socket, which for transporting audio packets is used. This channel can be either UDP or TCP. in the Generally, UDP is used because it is the latency to a minimum reduced. However, because some firewalls allow through UDP packets, is the audio channel may must use TCP. The talk tool indicates the mode (ie, TCP, UDP) or used an automatic mode in which the talk tool attempts a UDP test and at failure of UDP to TCP evades.

opening sessions can work with either full or half duplex. Full duplex is therein, if both users can talk at the same time. half duplex is, if only one user can talk. It will probably be, that a client device is not able to handle full duplex, as an example, if the CPU is too slow to audio simultaneously compress / decompress and / or the microphone and speakers are not can be open simultaneously. If a client device is marked as a half-duplex, then each used by this client device opening session regardless whether another device can handle the duplex mode, a half-duplex session. In one implementation, a support TALK / LISTEN button at the END TALK UI half duplex. This Button has two states: LISTEN (Listen) or TALK (Talk). When the talk session is full duplex, is This button is not shown. If both the transmitter<figref>702a</figref> as and the receiver <figref>702b</figref> on the button TALK is (initial Half duplex) may, the first user who clicks TALK speak, and the other user is forced to listen. The user who listens has, a dimmed TALK button (half duplex hearing), and the user who speaks, has a LISTEN button (half-duplex speakerphone mode). If the LISTEN button is clicked, allows the user speaks, the listening user, to speak.

the Speech tool that enables the audio transfer functionality (Talk) can be any, charged to a client device type of Client controller (z. B. software application program) be. the supports opening tool the use by various OSP and IM clients. The talk tool is for responding to user interfaces and translating user commands responsible in the appropriate actions with the client device. For example be of the opening tool to the physical components of the client devices, the for Audio are needed, open, read, written and closed. The talk tool also controls Audio and control channels, recalls accomplished are to a change in status display. When the talk tool is loaded, determines the talk tool, whether the client device for processing full duplex in the Location.

the Talk tool may also allow the user to adjust the volume for the loudspeaker and the microphone to control. In one implementation, saith User in a microphone, and the audio data are stored in memory recorded. Even in the recording mode, the average level the speaker's voice on a on a user interface the speech tools displayed level meter display. A slider is used the input level to an optimum value to adjust. After the speaker stops talking, the stored voice the speaker through the audio output device of &lt;?page 13?&gt;Computers played. The speaker level slider can be used to adjust the output level to an acceptable volume to adjust. When the user begins to speak again, returns repeating the talk tool to the recording mode back and the cycle themselves. Once the user is satisfied with the settings, can the user settings for use in subsequent speech sessions to back up.

the Talk tool may require additional functionality support, including among other things, multi-conferencing, Parking and mute. The Multi-Conferencing allowing more than two users to participate in a talk session. Parking permits stopping an active voice session to to connect to another talk session. The master circuit turn off the microphone to the full duplex mode user feedback / -Echo to prevent.

the Talk tool may also include security features to protect the integrity of transferred data to protect. For example, the talk tool data, by using a proprietary can compress algorithm or data in a proprietary protocol send. To further improve security, the talk tool the port numbers randomly of a large Select area.

in the Generally, a instant messaging session similar to a speech Telephone meeting, because it shares the same three states: not connected (Launched), Connect (ringing) and connected (Talk). These conditions and the ability are used to switch among them as described above by appropriate UIs supported, namely a START TALK UI (not connected), a CONNECT UI (ringing) and an END TALK UI (connected).
