<div>Thanks for your reply. As it turned out, the customer had a firewall issue that was blocking my SNMP. I'd checked over the configuration of CER and didn't see anything unusual before they discovered it. Everything appears to be fine now. Thanks for your reply!

These 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.

<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!
