Voip connecting but no voice out/in
I'm testing moving our Voip traffic onto its own voice vlan. We have Univerge 8100 with about 25 DT700's. Each phone has an Eithernet adapter so we just have 1 cable for each phone and pc.
We have a PoE Adtran Netvanta 1500 switch. I have everything working, switch is routing between vlans, trunks are working, pinging between both vlans working, and calls our going out of the gateway and back in.
The issue is the calls coming in and going out connect but I don't get voice. Everything local is working fine. So I figure it's probably something to do with a firewall rule or something. I have a static route on the sonicwall back to the switch vlan gateway for the traffic coming back in the network. We have a Sonicwall NSA.
Note: We didn't have any issues before when everything was on the same vlan.

When the VOICE data makes it back to the adtran/Voip router,
Usually you would use tagged VLAN identifier
Which VOIP PBX?

Our PBX is a NEC SV8100. We had trouble getting any of the IP Interfaces to change using the Webpro interface. Even after changing them, and applying the settings they revert back to what they were.
This system is quirky. We've had little issues with it here and there. Honestly I haven't found much info on it by googling other than manuals that don't give you much in the way of troubleshooting and very few people have experience with it that I've found.
I'm going to look into the firewall as the culprit and work my way back.

Where and what interfaces were implicated by the VLAN changes?
As you said, I am unfamiliar with this PBX.
Does it have one feed that is connected to your outside router, and one that feeds you PoE switch.
The issue if you VLAn'd both that causes the issue.
If you call your number by cell phone, do you get a "non connecting type of answer"? or as you said the connection is established and nothing is ....
does the PBX have Call data record, debugging.
The other issue is how your vlan is setup given you have one feed that is providing both voice and data (phone and computer)
depending on how you setup the VLAN, one option I would recommend is to revert back to what worked, while configuring one port on the switch to be the VLAN and diagnose what is going on that way.
Making multiple changes at the same time makes it extremely difficult to track which of the changes might be causing the issues you experiencing.
