jlumby Posted September 17, 2008 Report Share Posted September 17, 2008 I have one installation that is having a strange problem calling out, and it is intermitent. The problem only exists when calling across a trunk, internal calling works fine. When you dial the phone number, the phone just sits there, despite the dialplan telling it to dial, or pushing the dial button. In the background it authenticates with the PBX, however the PBX never sends the final sip packet containing the 200 OK. Then when I hang the phone up, and it cancels the call with the PBX, the pbx goes on to send the 200 OK and place the call through the itsp. This customer is running 220.127.116.1198 I have noticed that the pbx logs the error Via is empty, cannot send reply Despite the via field having content in it. I am attaching the pcap, and logfile to this post. The pcap was done from a remote phone, however the same problem exists within the office where there is no NAT Quote Link to comment Share on other sites More sharing options...
