Hi all, While testing pjsip (python 2.7 binding pjsua) we got an error on disconnect: sip_transactio ....Unable to register CANCEL transaction (key exists) 20/06/2015 11:03:19 session_process.py 134 11:03:19.428 pjsua_call.c ..Failed to send end session message: Object already exists (PJ_EEXISTS) [status=70015] 20/06/2015 11:03:19 session_process.py 134 11:03:19.484 sip_transactio .....Unable to register CANCEL transaction (key exists) 20/06/2015 11:03:19 session_process.py 134 11:03:19.484 pjsua_call.c ...Failed to send end session message: Object already exists (PJ_EEXISTS) [status=70015] We tryed to initiate a call and cancel it after 15 sec. But got an error. As i understand it's regards to sip transaction and CANCEL message should be part of transaction but error appears. So as in of RFC 3261 described CANCEL message should be part of sip transaction.
