Site To Site Extension Dialing

We recently upgraded to FreePBX at one of our other sites. They are connected together through a VPN and the two systems are connected together with an IAX trunk.

Extension to extension was working until the network team changed out the firewalls.
After much troubleshooting Site 1 can call Site 2 but Site 2 can't call site 1.
Under reports IAX info both trunks are connected and show registered.
The error message site 2 gets when call an extension on site 1 is "your simultaneous call limit reached, Goodbye."

Both trunks are set to 10 for Maximum Channels and I confirmed under the users/advanced section they are set to the default 3 concurrent calls.

Both sites also have an IAX trunk for outbound dialing which is working perfect to an IAX/SIP provider.

Here is my trunk data.
Outgoing
Trunk Name: Site 1
Peer Details
type=friend
qualify=yes
host=Site 1 IP address
deny=all
allow-ulaw
context=from-internal

Site 2 is the same just with the IPs and trunk name changed.
Incoming section is all blank and the outbound routes for these trunks are set to intra-company.

Thank you in advance for any help anyone can offer.
