Found where the issue was. Added new policy to the Security Zones for both the Public and Private interfaces from our internal LAN addresses and moved them to the top of the list so they would be looked at first. I did not realize that it was a trickle effect.
I was correct, it is indeed a firewall setting. The problem above is being caused by the 2.1 Adtran firewall settings. I've disabled them for the time being to try and get voice traffic to travel between the two offices. I am still however completely lost on setting up the firewall/Sec.Zones.
So with the firewall on both sides turned off I can ping between both networks. I need help with the firewall rules if someone would explain what they might try.
I've also got a SIP phone that's setup and pointing to the 4.2 adtran to use 2.x Asterisk server. It does in a sense. It can place and receive calls but there is no voice. Now when I had the 2.1 FW turned on it could still place and receive calls and voice was only on the other end of the call. People could not hear me but I could hear them just fine.
Attached is that 2.1 Adtran i've mentioned.
