(Sorry for the previous email which was in HTML format) Hello everyone, ? I'm trying to use pjsua to make a call. The registration process works fine but when I make a call I notice a strange behavior: the INVITE message is sent, I receive a "Status: 100 Trying" message and then I keep receiving "Status: 183 Session Progress" messages until the recipient answers. ?The communication is then established but I think some SIP messages are missing (for instance there is no 200 OK message)? and this leads to an incorrect state (I do not know when the call is established, how long it lasts, etc.). ? (I tried to make the same call with a different softphone (XLite) and I get a different behavior: INVITE - 100 Trying - 183 Session Progress - 180 Ringing. And when the recipient answers I get 200 OK) ? Any help to understand what is going on and how to get the standard behavior would be greatly appreciated. ? Here is the log displayed in pjsua and the details of some SIP messages (slightly modified for privacy concerns): ? 02:31:35.649 ? ?pjsua_app.c !..Turning sound device ON 02:31:35.699 ? ?pjsua_app.c ?.......Call 0 state changed to CALLING 02:31:39.446 ? ?pjsua_app.c !.....Call 0 state changed to EARLY (183 Session Progress) 02:31:39.448 ? ?tsx0060CD0C ?......Failed to send Request msg PRACK/cseq=17029 (tdta0060BCA0)! err=70018 (gethostbyname() has returned error (PJ_ERESOLVE)) 02:31:39.981 ? ?pjsua_app.c ?.....Call 0 state changed to EARLY (183 Session Progress) 02:31:41.081 ? ?pjsua_app.c ?.....Call 0 state changed to EARLY (183 Session Progress) 02:31:43.181 ? ?pjsua_app.c ?.....Call 0 state changed to EARLY (183 Session Progress) 02:31:47.280 ? ?pjsua_app.c ?.....Call 0 state changed to EARLY (183 Session Progress) ? // The recipient answers and we can communicate ? // I decide to hang up (if ?it is the recipient that hangs up I get this after a few seconds: Call 0 is DISCONNECTED [reason=500 (Server Inernal Error)]) h ? 02:31:54.231 ? ?pjsua_app.c ?.....Call 0 is DISCONNECTED [reason=487 (Request Terminated)] 02:31:54.232 pjsua_app_comm ?..... ?
