If by "register is successful" you meant SIP registration was successful, pj_thread_register() has got nothing to do with SIP registration. It could be that you are calling pjsip API from thread that is created by API other than pj_thread_create(). You *can* do this, but as the message suggests, you'll need to "register" that thread first to pjlib. Please see this for info on pj_thread_register(): http://www.pjsip.org/pjlib/docs/html/group__PJ__THREAD.htm#g600d2f8baddfd78de3b6b60cce027a9a -benny > thanks!
