Hello,
I'm attempting to connect our Telrad TVSe to another system with SIP. The other side is the latest copy of AsteriskNOW, a popular open source PBX. I think I'm close, but I'm lacking documentation and the ability to debug the Telrad side, so I've hit a bit of a wall.
Previously the system had 4 SIP DNs on the TVSe in the same trunk group, all pointing to Gateway #1, which is the IP address of another TVSe. For my testing I decided to steal one of these channels since only one person in the office uses this bridge, and he certainly doesn't need 4.
I added a Gateway #2 in eManager using the IP and port of the Asterisk box. Then I told the last DN in the trunk group to use Gateway #2. I also created a corresponding SIP trunk in Asterisk that points at the Telrad box.
So far they seem to be trying to talk to each other, but I can't get a call started from either side. When Asterisk tries to call Telrad, it gets a 480 Temporarily Unavailable response in the logs. I haven't had as much luck trying the other way because I'm not sure where to look for logs.
When I log into the TVSe's web portal, I can see the trunk shows
out of service. The corresponding status on the Asterisk box actually says its up. This leads me to believe that either I need to do some additional massaging of the Asterisk config to make it Telrad compatible, or possibly that the steps I did above to add the gateway were wrong.
This is a good learning experience for me, so I what to try to work the problem myself as sometimes we only learn by tinkering and tormenting ourselves. But I need a pointer on where to go from here. Does anyone have the documentation the SIP trunking settings in eManager? Where can I debug and see error messages on the TVSe? I saw the TCP dump thing, but it just seems to be raw traffic and not error messages. Do I need to step back and reconfigure the Telrad side differently?
Thanks in advance for any help.
