Switchvox phone issues

Have you checked the "port translation" on the Sonicwall?
-
I don't have any access to the Sonicwall, and am not familiar with their setup.
I can ask the vendor, what specifically should they be looking at? -
Sounds like you need to Fire your vendor.

Data comes in on port x, data exits on port x+1.
This causes problems for SIP traffic. -

Client will not replace the Sonicwall and insists that they do this all the time and never have any voip issues with Sonicwall. They now want to do a L2L VPN tunnel for the voice network back to the internal IP of our PBX. I would rather not do this, but the boss wants the issue resolved.
Oh, this is a client not internal? Keep the SonicWall, that's a consultants' dream gear. Breaks constantly needs loads of hours to support. If they want a VPN, they are pretty clear that they know the SonicWall doesn't work.

Client likes the situation, though. So not his problem.
-
Oh well If they are your client and they refuse to replace I guess that is a bonus for you.... more billing.

Exactly. Clear conscience that the proper resolution was recommended. Now he can happily bill without feeling badly. Win / win.

Now, they outsourced their IT, and got another internet connection that they are using through a SonicWall appliance, so all the phones were switched to register to the public IP of our phone server over their new internet connection.
OK, so there's a third party IT group involved here. Did you tell them, the third party IT group about the known issues with SonicWalls and VOIP, or did you tell the actual client of yours?
Since they used to be a direct client, that then changed IT departments, it's hard to say who you even have a right to talk to at the ultimate end user.
Assuming you still have the right to talk to the ultimate end user - I would call those folks directly, inform them of the issue (i.e. the new IT company is refusing to replace the end user's firewall for something that is know to work, and instead the end user is getting bilked not only for the IT companies extra billing, but also the potential extra costs coming from you, the phone provider).
If the end user then says - do what the IT company wants, then you're hands are truly clean, BILL BILL BILL!

we ended up going the route of the L2L VPN to get the phones to work. Vendor insisted he has never had any VOIP issues with Sonicwall and didn't want to budge on that. After a day of them figuring out how to put the phones on a separate Vlan and then getting that traffic to the firewall, we finally got the vpn up and working and the phones registered again. All in all a very frustrating experience, thanks to everyone here for the help.
If only we could charge by the hour, but we don't as we are one gov agency helping another.
If anyone else here besides SAM will be in Austin later this year, see you at Touche's. -

Even while it doesn't work. So you know that he'll say this to other customers now, even after this one. Chances are, he's had problems at all customers. SonicWall is culprit #1 for VoIP issues. I mean that literally. I get a call that someone has VoIP audio issues, my first question is always "Do you have a SonicWall?" Nine times out of ten, the answer is yes and nine times out of those ten, the SW was the issue. It's nearly a sure bet with audio issues.
Had you led this question purely with "I have these audio issues..." we'd have said "I bet you have a SonicWall."
