Hi, I've been seeing crashes related to audio session interruptions on the iphone for a while, and just got one while the app is connected to a debugger. I've attached the logs, I had made a call on cellular and just switched back to the PJSip based app. I have numerous crash logs showing the same thing but today is the first day I could catch it in the debugger. Don't know if this helps, I'm running current trunk. 18:08:27.718 coreaudio_dev. Session interrupted! --- Begin Interruption --- Assertion failed: (mutex), function pj_mutex_lock, file ../src/pj/os_core_unix.c, line 1203. Program received signal: ?SIGABRT?.
