Hi I'm new in using pjsip and I'm trying to build a sip client. I was able to register to the sip server. But when trying to make call, I have an error Sip log. Level : 4, 19:54:43.004 pjsua_call.c Making call with acc #0 to sip:1514XXXXXXX at dev1:5060;user=phone Sip log. Level : 1, 19:54:43.005 pjsua_call.c Error initializing media channel: Object is busy (PJ_EBUSY) [status=70011] Then later I got an exception entry->cb != ((void*)0) What should I do about it ?
