Yealink T46u not working over Verizon

[LarkyBark]

We have several other model Zoom phones we tested over a Verizon 5g connection and they all worked perfectly. However, we have a new Yealink T46u from Zoom and this phone cannot make outgoing calls. It can receive calls and it connects to Zoom just fine. It will error out eventually when trying to make a call saying "No Invite Response Received!"

I initially thought it was the router however there is nothing being blocked as indicated by the logs, and the packet captures show successful communication to the Zoom servers.

The T46u has the latest firmware and multiple factory resets have been done.

Any ideas?
