two things need to be enabled on all switched between the devices to be
discovered & the CER servers. Also make sure all clusters & switches are
in the SNMP config of CER & that the read only SNMP account is configured
properly. Switch HW & SW need to be compatible with the version of CER,
check CER release notes.</FONT></SPAN></DIV>

<DIV>I have a CER cluster located on a central CM cluster. There are two
remote CM clusters connected via inter-cluster trunk to the central
cluster. I can see phones from the central cluster registered to switch
ports within CER, but can't see the phones from the remote clusters registered
to the ports they're connected to. Do I need to do any CTI integrations
within CER for the remote clusters to get those phones recognized. Any
thoughts would be helpful. Thanks in advance! </DIV>
