I read through your question a couple of times. Basically you have
server A which has extension 2000 and 5550. Server B has extension
2000 and 2001. You configure a (soft)phone as extension 2001 and
dial 5550 which succeeds but you dial 2000 and the call fails.<br>
<br>
Have you tried turning up the debug verbosity in the console and watching the
call flow on Server B? I don't know what would prompt Server B to try
passing the call to Server A but that should become apparent in the debug
information.<br>
<br>
If the 'domain' you are referring too his the FQDN then that has nothing to do
with the price of bread as far as I can tell. <br>
