[Asterisk-Users] adding a thrid asterisk server

[MDM]

To All

I am a new to Asterisk and dialplans have me stumped
I just inherited 2 Asterisk server conected as IAX peers.

Now from what i can tell when Asterisk Server (ask-chic) needs to make a 
call to an extension
which resides on the other server (ask-MAIN) it goes over a IAX channel.

Now i am trying to add that third asterisk server to mix (ask-SD) and i 
figured i would do it in baby steps.
The first thing i did was configure two local SIP client so they could 
call each other and leave voicemail.

Then i tried to  add (ask-SD) to (ask-Main) as a IAX peer. Just like 
(ask-chic).
To test i tried dialing an (ask-SD) ext from a phone off the (ask-MAIN) 
server.

The call did not go through. However i watched it from the CLI> and 
captured the following output. What could be wrong. i am so stumped.
