I am having problems with some phones that do not seem to be tracked by Emergency Responder(1.2.3). On a given switch I might have 22 phones that are correctly recognized in ER but one or two that are not, even though they are registered in CallManager (4.0.2asr1a) and show up in the "show cdp nei" command.
I am looking for ideas for what to look for in order to solve this problem.
The phones that do not show up in CER > ERL Membership (in other words, not being tracked by CER), are registered to which CallManager? Check the SNMP Community string configured on that CallManager's SNMP Service in Windows Services. The string should match the SNMP community string configured in CER for that CallManager.
CER should be able to talk SNMP with the CallManager to which the IP Phones are registered.
If eveything seems fine, restart the SNMP Service on the CallManager, and see if that helps.
What version of IOS/CatOS? What kind of switch? Any SR installed in the CER server? What type of phone? Have you tried to restart SNMP on the CER server? If swap this phone with another port that was able to discover is the phone seen in CER, does the problem follow the phone or the port?
