You need to do a local PBX lookup for the extension, if not present then do
a DUNDi lookup to the peer PBX and pass the call over there.  Also keep
rtcachefriends=yes enabled so asterisk caches the sip registrations.  You
can also just dip the database and get the 'ipaddr' and 'port' info to call
the extension directly.

Give this a read if you haven't already.
