Kahele Nakaahiki Posted February 4, 2013 Report Share Posted February 4, 2013 Hello, I'm having an issue where calls are dropping between mine 2 snom systems after exactly 2m 32s. One snom system (lets say A.) is on version 2011-4.3.0.5021 (Linux) the other (let say B.) is a Snom One Plus appliance on version 2011-4.5.0.1030 Beta Corona Austrinids (CentOS32). I can make calls from B to A without issue but any calls originating in A and going to B drop after the before mentioned time. All other trunks (SIP providers) out of each system have no issues. This is the last thing I see in the log as the call drops.

Vodia PBX Posted February 4, 2013 Report Share Posted February 4, 2013 Well that log is from the phone, that probably does not help much. The question is how the systems are connected. Are they able to "see" each other, meaning can they send packets to each other directly or is there NAT involved? Quote Link to comment Share on other sites More sharing options...

Are they able to "see" each other, meaning can they send packets to each other directly or is there NAT involved? There is an edge device sitting between the 2 systems now and the B side is now using NAT at the edge devive. All communications on the A side hits the PBX directly.

Vodia PBX Posted February 5, 2013 Report Share Posted February 5, 2013 Hmm. Any chance that the two PBX can send packets directly to each other, for example through a VPN? Edge devices are complex and it is easy to make mistakes. Quote Link to comment Share on other sites More sharing options...

I was hoping it was a problem that could be resolved from the Snom as our SIP provider didn't seem to know how to remedy the issue from their edge device. Thanks for the help.
