I've investigated more, and found the following: When our app detects a change in network (i.e. changing from wifi to 3G or wifi->different wifi, or even losing signal entirely) we shutdown pjsip using pjsua_destroy() then, if/when a network is available we reinitialize pjsua using the same startup code we used in the first instance. When restarting pjsua I see the following error: 08:13:52.942 sip_endpoint.c Module "mod-invite" registered 08:13:52.942 coreaudio_dev. dev_id 0: iPhone IO device (in=1, out=1) 8000Hz 08:13:52.942 coreaudio_dev. Error: cannot initialize audio session services (1768843636) 08:13:52.943 coreaudio_dev. core audio initialized 08:13:52.943 pjlib select() I/O Queue created (0x9dba14) 08:13:52.979 sip_endpoint.c Module "mod-evsub" registered At this point, when I go to make a cellular call, I'll see the same crash I pasted (pasted again for completeness 08:14:57.383 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?. At As far as I know the only way to get pjsua to work correctly with the new network interface (be it the 3G WWAN or WIFI Network) is to call pjsua_destroy and then start up pjsua again. If this is incorrect I'm happy to change my code. If I do not shutdown/restart pjsua eventually I just start getting 502 (Timeout) responses from pjsua.
