SIP Issues IPO v9.1.12.0 build 212 Flowroute SIP Trunks

[vobarex77]

Got a weird issue ive never seen before.

Our Flowroute SIP trunk is going down and up. Ive been testing inbound on this new circuit several times a day, sometimes it works, sometimes it doesnt. Ive opened up all traffic for the SIP service, forwarded all the ports, etc. We have a SonicWall, is the firewall my issue? What would be the best way to submit some sort of Monitor trace, im tracing everything the trunk does currently and the only thing im seeing is this....

Also - cant get my STUN to return anything.

Any direction is helpful. Thank You in Advance.

Not enough information to tell you what the issue is...

A few questions off the top of my head:
How is the network topology tab setup?
Do you have SIP ALG enabled?
Do you have keep alives enabled?

The truth is just an excuse for lack of imagination.

Here's a guide I wrote to confige a SonicWALL for SIP Trunking with Flowroute. The document can be adapted to just about any SIP provider.
