One way audio on Panasonic IP phones via Sonicwall site to site VPN

We've had this setup working for years with an NSA 240 at the main location and a TZ100W at the remote location. Phone worked great without any issues.  Now we're running into an issue where the phone at the remote location can no longer hear audio from the caller.  I swapped out the NSA240 for a TZ500 last night, but same issue remains.  Site to site VPN is up, and file access works, but the phone is still only getting the one way audio.

Any ideas?

is one of the following features enabled?
Consistent NAT
H.323 transforms
SIP transforms

if so, for VoIP over VPN do not use these! Only if you have VoIP over the WAN.



View example configurations and the SonicWALL webui and features on http://livedemo.sonicwall.com or http://ngfw-demo.com

Multiply the effectiveness of your APT Sandbox, stop unknown and zero-day attacks at the gateway. See a demo on http://apt-demo.com or http://atp.demo.com

No, none of that stuff is enabled.  I am currently removing some changes I made Monday when trying to get AT&T fiber going.

This usually happens if something is not using the correct IP address, this usually happens through a NAT device.
But you have a VPN and have the transforms disabled (on both ends??)

so this shouldn't be the case....

Turned out to be some settings that I had added when trying to get AT&T fiber "static" IP's (actually behind their NAT'd router) to work on the Sonicwall.  Removed all those settings, rules, etc. and phones went back to normal.
