[VoiceOps] Allworx Followme - no audio issue

[Ujjval Karihaloo]

Its NAT'ed

It does work for a normal call forward. Only followme with Answer
Confirmation is what causes no Audio.

I wanted to see if someone has run into this. I am collecting traces from
Customer PBX also now to take a deeper look and compare.

Is the Allworx WAN port on a public IP or are you NATing the Allworx
through a firewall?
