SIP Call Flow - Help

Posted:Tue 12 of Jul, 2011 (20:49 UTC)
Hi all,

I want to understand what happened with this call. It appears to not have completed, but what info do I look for to determine why?

Call is between internal user extension to internal conference line:

originator | INVITE SDP ----> |destination
originator | <----- 407 Proxy Auth Required |destination
originator | ACK ----> |destination
originator | INVITE SDP ----> |destination
originator | <----- Trying |destination
originator | <----- 200 OK SDP telephone-event |destination
originator | ACK ----> |destination

-- END of call flow in my capture ---

Thanks!
