Hi, Not really aware about this issue, or perhaps platform specific issue (?). And just FYI, the auto-answer feature in pjsua is handled in the worker thread context (not main thread), and it just works fine on (at least) win, mac, linux/unix, please check on_incoming_call() of pjsua_app.c. People usually face thread problem caused by missing external thread registration (into pjlib), please see doc of pj_thread_register() [1] for more info: --- [1] http://www.pjsip.org/pjlib/docs/html/group__PJ__THREAD.htm#g600d2f8baddfd78de3b6b60cce027a9a BR, nanang On Fri, Apr 9, 2010 at 2:12 PM, Jerry Augustine <jerrya at excelanz.com> wrote: > Hi All, > > Are there any considerations to be kept in mind regarding threads when > working with PJSIP? > > E.g.
