There is very little available via SNMP on the TelePresence endpoints (sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation, sysServices), and on the newer versions of the CE endpoint software SNMP is disabled by default.
If you want to monitor stuff that's more useful, then you're better off using the xAPI to request from a wider set of information available on the endpoint.
