I have posted this over at uk.telecom.voip, but just in case someone here knows the magic combination, I though I would ask here too!
I am REALLY struggling to get a SIP trunk working on my IP Office 406 (5.0) with a SonicWall NSA 3500 in the way.
Has anyone here manage to get this working?
The SonicWall has a number of WAN connections (all with static IP's) and one LAN connection, which is connected to (amongst other things) LAN1 of the IP Office.
If I connect the WAN connection to LAN2 on the IP Office, it works absolutely fine, but I really would prefer the SonicWall to be in the way, for better security, and also so we can switch to using different WAN connections if there is a problem with the primary one.
The best config I have at the moment is allowing incoming calls to work properly, but outbound calls are not passing audio in any direction ;(
If you have managed to set this up, and don't mind sharing your wisdom, I would be very grateful!
My provider specifies two IP addresses their end, one used for signalling, and the other for media, signalling needs to pass port 5060 and media ports 6000 -> 40000
Many thanks!
