style='font-size:10.0pt;font-family:"Lucida Sans";color:blue'>Looks like you've
got the basics down. If the connection between offices is data then just
create an ICT pointing to the servers in the other cluster (and do the same on
their side) and use a route pattern to route calls via the
ICT. Make sure the IP routing works to their servers and from their
voice vlan to yours and you'll be good to go. For QOS between them ICT
calls are just like H.323.</span></font><o:p></o:p></p>

to establish office to office extension dialing as soon as possible. </span></font><o:p></o:p></p>

having to change extension ranges. For example if they have an ext 2352

of routing calls to those offices extensions out to the PSTN, I would route
