[cisco-voip] Emergency Responder Question

[Mike Lay (milay)]

The key part for phone discovery is CDP & SNMP. 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.
 
Some other considerations that need to be taken for multiple cluster.
 
1) All clusters must be running the same point release of CCM, JTAPI
limitations
2) Overlapping dial plans are bad, same DN on multiple clusters
3) CCM servers should be collocated with the CCM clusters or at lease

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!
