style='font-size:10.0pt;font-family:Verdana;color:black'>You can connect
clusters together via PSTN gateway, e.g. T1s or via IP, e.g. intercluster
trunk.<br>
<br>
I would investigate an intercluster trunk. Very easy to setup and you add it to
a route group. If you have more than two clusters, you can still use an
intercluster trunk, but then you have 6 trunks instead of two, basically fully
meshed. Still manageable, but more than 3 you should consider a gatekeeper.<br>
<br>
This page should help you out:<br>
