We are compiling pjsip from SVN trunk with iOS 4.0.1 SDK without any sound issues running on iOS 3.1.2/3.2/4.0 devices. How are you compiling it? I suggest checking out pjsip from SVN trunk, and use the guide on the pjsip wiki for compiling for the iPhone (use configure-iphone script) Best regards, Even Andr?

However the moment we switch to iOS SDK 3.2 everything works fine. So right now, we are building PJSIP on 3.2 - once built on 3.2, our application when deployed in an iphone 3G (3.x) or iphone 4 (4.0.1) works fine. Our conclusion therefore is that pj1.6 has some issues in the audio driver for iphone when compiled with iOS SDK 4.0 - correct? > > 2) The PJSIP initialization function takes at least 10-12 seconds when in debug mode on an iphone 4. Is there any way to make it faster? Alternately, we do not receive any notification from PJ when init is complete, so when we start our VoIP client, we have no idea when PJ is ready to make a call - so we cannot display a "initializing" message that g goes away when PJ is ready to make calls. > > 3) Has anyone got DTMF via RFC 2833 working on iphone? We currently use PJSIP on android and everything works fine with 2833 DTMF. When we use the iphone client, RTP seems to be sent via inband RTP and not 2833 (yes, we have validated that the remote end returns 2833 support in 200 OK) > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >
