By the way, I noticed that on revision 4722 of pjsip, by using the regular iOS build commands as described on the Getting Started page (http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone#no1) some libs are not being built correctly on my machine. More specifically: third_party/lib/libmilenage-arm-apple-darwin9.a I checked out multiple revision, ran my build script on them, and found out the problem was on revision 4720 (up to revision 4719 everything built correctly). 4719 already has pjsua2, so I tried using this build with my code, but the audio problem continues. -------------- next part -------------- An HTML attachment was scrubbed...
