Hello list, I've researched this issue quite a bit before posting it here, so I'm now fairly confident this bug/issue is with PJSIP's implementation of ZRTP and not an Android or CSipSimple issue. In a nutshell, as I reported in CSipSimple's issue tracker here http://code.google.com/p/csipsimple/issues/detail?id=2378 , all my ZRTP enabled calls crash after a few seconds with the log full of these error messages: "zrtp_android.c !ZRTP warning message: Dropping packet because SRTP replay check failed!" I don't see anyone reporting the issue here, and I believe CSip basically uses PJSIP's code for its ZRTP and SRTP implementation, so I think the root of the problem lies in PJSIP. I've experimented with different phones (Samsung S3 LTE running 4.2.2 as well as Sony Xperia running stock 4.0.4) and the crashes always occur with ZRTP. Plain old (SDES based) SRTP calls are fine though. Let me know if there's anything I can do to help or if you need more logs and/or info.
