Patent ID: 7545802

Claim:
A method for providing an optimized audio quality communication session between a near end and at least a far end telecommunications terminals, each telecommunications terminal having a codec, while at least the codec of the near end telecommunications terminal being able to apply two alternative encoding techniques belonging to the same audio compression protocol, the telecommunications method comprising the steps of: setting up a communication session between the two telecommunications terminals by fixing the audio compression protocol to be used between the two codecs; sending from the near end telecommunications terminal towards the far end telecommunications terminal a data packet using the encoding technique based on the most technically demanding alternative; receiving by the near end telecommunications terminal a data packet from the far end telecommunications terminal; whereby the further steps of: determining by the near end telecommunications terminal out of said received data packet the encoding technique used by the far end telecommunications terminal; in case said determined encoding technique being based on a different alternative encoding technique of the audio compression protocol then adapting the encoding technique to be used by the near end telecommunications terminal to said determined encoding technique when proceeding said communication session, wherein said codec of the near end telecommunications terminal is operable to apply the two alternative encoding techniques belonging to the same audio compression protocol.
