Hi Team, Currently I am working on Android application which uses PJSIP. I have a service which handles all the call backs of PJSIP call. When I answer/Reject a call form Main application, I am getting below exception 08-04 13:42:29.707: A/libc(31926): ../src/pj/os_core_unix.c:674: pj_thread_this: a ssertion "!"Calling pjlib from unknown/external thread. You must " "register external threads with pj_thread_register() " "before calling any pjlib functions."" failed Is there any work around for this? -- regards Pradeep B K -------------- next part -------------- An HTML attachment was scrubbed...
