Method for providing optimizd audio quality communication session and corresponding terminal and computer readable medium

A method for and at least far-end electric terminals providing optimizing audio of communication session's method between the proximal, the set at least a telecommunication terminal can be applied to belong to the same audio protocol two replacing coding technique. The comparing is a audio protocol the communication session, wherein the near-end telecommunication a terminal and a data packet of far-end telecommunication terminal, comprising a least one receiving data packet to determine of a coding method for telecommunication far-end terminal is used for. The executing by masthead content of the receiving packet. The determining coding with method based on is a telecommunication terminal first an audio protocol the condition of replacing the coding method, wherein a a pluggable adaptation method.
