Abstract:
Idle DSP channels of an IP phone can be used to respond to a request to transcode a codec of an incoming call in a distributed IP phone system but only if sufficient idle channels remain available to the phone to handle basic call functions and a possible non-basic call feature (such as conferencing) of the phone.
