Hi All, I have the next scenario: 2 endpoints, "A" cisco IP Phone, "B" "PJSIP IP Phone". When "A" calls "B", at "B", a Timeout timer event occurs. Does anyone knows what is happening? Below, you can see the output of the terminal : 00:36:53.573 sip_endpoint.c Processing incoming message: Request msg INVITE/cseq=1 (r) *00:36:53.578 tsx0x11a5e4 Transaction created for Request msg INVITE/cseq=1 (rdata0) * 00:36:53.579 tsx0x11a5e4 Incoming Request msg INVITE/cseq=1 (rdata0xc2fb4) in statl 00:36:53.579 tsx0x11a5e4 State changed from Null to Trying, event=RX_MSG 00:36:53.580 dlg0x119ddc Transaction tsx0x11a5e4 state changed to Trying 00:36:53.581 dlg0x119ddc UAS dialog created 00:36:53.583 dlg0x119ddc Module mod-invite added as dialog usage, data=0x11a3c0 00:36:53.584 dlg0x119ddc Session count inc to 2 by mod-invite 00:36:53.585 inv0x119ddc UAS invite session created for dialog dlg0x119ddc 00:36:53.586 endpoint Response msg 100/INVITE/cseq=1 (tdta0x11c5c8) created 00:36:53.587 dlg0x119ddc Initial answer Response msg 100/INVITE/cseq=1 (tdta0x11c5) 00:36:53.587 inv0x119ddc Sending Response msg 100/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.587 dlg0x119ddc Sending Response msg 100/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.588 tsx0x11a5e4 Sending Response msg 100/INVITE/cseq=1 (tdta0x11c5c8) in g 00:36:53.589 sip_resolve.c Target '192.168.1.3:5060' type=UDP resolved to '192.168.1P 00:36:53.591 tsx0x11a5e4 State changed from Trying to Proceeding, event=TX_MSG 00:36:53.591 dlg0x119ddc Transaction tsx0x11a5e4 state changed to Proceeding 00:36:53.594 inv0x119ddc SDP negotiation done, status=0 00:36:53.598 inv0x119ddc Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.598 dlg0x119ddc Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.599 tsx0x11a5e4 Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) in g 00:36:53.600 tsx0x11a5e4 State changed from Proceeding to Completed, event=TX_MSG 00:36:53.601 dlg0x119ddc Transaction tsx0x11a5e4 state changed to Completed 00:36:53.603 inv0x119ddc Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.603 dlg0x119ddc Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) 00:36:53.604 tsx0x11a5e4 Sending Response msg 200/INVITE/cseq=1 (tdta0x11c5c8) in d 00:36:54.083 sip_endpoint.c Processing incoming message: Request msg ACK/cseq=1 (rdat) 00:36:54.083 tsx0x11a5e4 Incoming Request msg ACK/cseq=1 (rdata0xc2fb4) in state Cd *00:36:54.084 tsx0x11a5e4 State changed from Completed to Confirmed, event=RX_MSG* 00:36:54.084 dlg0x119ddc Transaction tsx0x11a5e4 state changed to Confirmed * 00:36:54.590 tsx0x11a5e4 Timeout timer event* 00:36:54.591 tsx0x11a5e4 State changed from Confirmed to Terminated, event=TIMER 00:36:54.591 dlg0x119ddc Transaction tsx0x11a5e4 state changed to Terminated 00:36:55.100 tsx0x11a5e4 Timeout timer event 00:36:55.101 tsx0x11a5e4 State changed from Terminated to Destroyed, event=TIMER 00:36:55.101 tdta0x11c5c8 Destroying txdata Response msg 200/INVITE/cseq=1 (tdta0x1) 00:36:55.102 tsx0x11a5e4 Transaction destroyed!
