Hi,
I'm updating the simpleUA example to be able to manage SIP Early Message.
I need too add an header on the PRACK message generate automatically by INVITE session intiated with PJSIP_INV_REQUIRE_100REL option.
So I have added a function on_tx_response and set it in the pjsip_module. Compilation is ok, but during execution, when PJSIP gnerate the first response (183), an error occurs :
16:58:12.010 dlg0x9498fbc Initial answer Response msg 183/INVITE/cseq=14875 (tdta0x949fe80) 16:58:12.010 inv0x9498fbc Sending Response msg 183/INVITE/cseq=14875 (tdta0x949fe80) 16:58:12.010 dlg0x9498fbc Reliable response Response msg 183/INVITE/cseq=14875 (tdta0x94a50b0) created 16:58:12.010 tsx0x949e2ac Sending Response msg 183/INVITE/cseq=14875 (tdta0x94a50b0) in state Trying 16:58:12.010 tsx0x949e2ac Error sending Response msg 183/INVITE/cseq=14875 (tdta0x94a50b0): Err=1 (Unknown error 1) 16:58:12.010 sip_resolve.c Target '127.0.0.1:5065' type=UDP resolved to '127.0.0.1:5065' type=UDP (UDP transport) 16:58:12.010 tsx0x949e2ac Failed to send Response msg 183/INVITE/cseq=14875 (tdta0x94a50b0)! err=1 (Unknown error 1) 16:58:12.010 tsx0x949e2ac State changed from Trying to Terminated, event=TRANSPORT_ERROR 16:58:12.010 dlg0x9498fbc Transaction tsx0x949e2ac state changed to Terminated 16:58:12.010 simpleua.c Call DISCONNECTED [reason=503 (Service Unavailable)] 16:58:12.010 simpleua.c One call completed, application quitting...simpleua_early: ../src/pjsip-ua/sip_100rel.c:353: pjsip_100rel_end_session: Assertion `pj_list_empty(&dd->uas_state->tx_data_list)' failed.Abandon
But my function is very simple (just trying add it before do anything else) :
static pj_status_t on_tx_response( pjsip_tx_data *tdata ){
return PJ_TRUE;}
I don't uderstand why.
Thanks by advance for the responses.
C?dric.
