I want to use PJSIP to develop a sip Gateway, now my problem is I can use pjsua to make call with my sip IP phone. but I donot know how to send/ receive voice data from IP phone with codec PCMa or PCMu, I need get the voice data save to buffer in memory, also need send some buffer with pcma or pcmu voice data to the IP phone. could you tell me the APIs? if possible, give me some example source code? Thanks very much. _________________________________________________________________ MSN ???????????????????? http://cn.msn.com -------------- next part -------------- An HTML attachment was scrubbed...
