Adding a 2nd PBX

Hope someone can provide a good learning resource for this, or pick up a few things I am doing wrong.  I'm trying to setup FreePBX to test, but we are not replacing the current PBX.  Disclaimer that my FreePBX may be all wrong, but judging by my debugging, the Adtran 908e is not right yet either.

We have a SIP trunk for local numbers and outgoing, and another SIP trunk for toll free.

I added voice trunk T04 for the new test PBX, changed the accept cost of a group of DID's, and created voice grouped-trunk SIP_GROUP_2 with the new trunk and lower accept cost.  The trunks and grouped-trunks are as follows:

voice trunk T01 type sip

  description "SIP TRUNK"

  caller-id-override number-inbound 9 if-no-cpn

  sip-server primary 192.168.1.10

  sip-server secondary 192.168.1.20

  check-supported replaces

!

voice trunk T02 type sip

  description "Toll Free"

  sip-server primary 67.x.x.x

  authentication username "asdfg" password encrypted "asdfg"

!

voice trunk T03 type sip

  description "Local DID"

  sip-server primary 8.x.x.x

!

voice trunk T04 type sip

  description "Test PBX"

  sip-server primary 192.168.1.8

  grammar from host local

  transfer-mode network

!

voice grouped-trunk "SIP GROUP"

  description "Production Servers"

  trunk T01

  accept $ cost 0

  accept 555999640X cost 0

  accept 555999641X cost 0

  accept 555999642X cost 0

  accept 555999643X cost 5

!

voice grouped-trunk LEVEL3_SIP

  description "TOLL FREE"

  trunk T02

  accept 5554069600 cost 0

  accept 18001234567 cost 0

  accept $ cost 10

!

voice grouped-trunk SIP_LOCAL

  trunk T03

  accept $ cost 5

  accept 411 cost 0

  accept 911 cost 0

!

voice grouped-trunk SIP_GROUP_2

  description "Test PBX"

  trunk T04

  accept 555999643X cost 0

I can list a lot more debugs, but this is the first Rx and Tx group on a call from FreePBX that fails:

192.168.1.21 is the Adtran IP.

208.x.x.x is our office IP

1234567890 is the cell phone I'm calling

1234561234 is our caller ID / main number

I'm really confused why the Contact is our office IP with FreePBX, and the local IP for our production PBX.  Maybe I have the firewall setup incorrectly on FreePBX?  Besides that, do the trunks, groups, and accept lines look like they will work?

Here are the first few lines from a successful call from our production PBX:
