Connecting two FreePBX boxes with a SIP Trunk

Hello

I have Server A and Server B. I want to configure a SIP trunk between the two servers so that all outbound calls on Server A route through Server B which is connected to my carrier.

I've got a SIP trunk registered between them both, but when I attempt a call, it never hits Server B. Server A provides the following output:

Here are my trunk config's for both servers..

Server A
type=friend
context=from-internal
qualify=yes
host=IP ADDRESS OF SERVER B
insecure=invite
allow=all

Server B
type=friend
context=from-internal
qualify=yes
insecure=port,invite
host=CARRIER IP
fromdomain=CARRIER IP
disallow=all
allow=g729,ulaw

Can someone please help me understand what is wrong with my trunk config?

Thank you so much!
