Well, there is this API:

http://wiki.freeswitch.org/wiki/Mod_commands#uuid_media

You might be able to do something like api_on_answer on the bridge. The key
for you is just doing a condition that matches when the caller and callee
are in the same office. All things being equal, how do you know when the
caller and callee are in the same office?
