color=#0000ff size=2>This all comes down to the fact that a CM group can only
have 3 servers. The trunk has a device pool assigned which is where
it inherits the CM group. Those 3 servers can be used for the outbound
call. As Lelio mentioned the ICTs must be defined as fully-meshed
because any of the servers in the CM group can be used for the outbound call.

<DIV style="FONT-SIZE: 10pt; COLOR: #000000; FONT-FAMILY: Verdana">Exactly. Oh,
something else you'll find out eventually, so in the interest of complete
disclosure....you can have a maximum of three servers per intercluster trunk. So
if your cluster has 6 servers, you will actually need two intercluster
trunks.<BR><BR>If you have 3 clusters, each with 6 servers, for full redundancy,
you will need 12 intercluster trunks.<BR><BR>A gatekeeper begins to make sense
fairly quickly. ;)<BR><BR><BR>---<BR>Lelio Fulgenzi, B.A.<BR>Senior Analyst

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
