Hi, I am running PJSIP 1.7 on an iphone (3GS as well as 4). I checked out the trunk today and built it exactly as per specs. When I make a call and switch the iphone to speaker mode, the remote party hears his/her own voice back very prominently. According to the release notes of 1.7, it should be using the iphone's native echo canceller and this should not be happening (or, atleast, the remote echo should not be so prominent). Is there any additional setting I need to do? I assume 1.7's audio driver should already be doing what the old http://code.google.com/p/pjsip-iphone-audio-driver/ effort did. Is that correct? (since this was created for older versions of JPJSIP and PJSIP has evolved since) thx -------------- next part -------------- An HTML attachment was scrubbed...
