Attempting to clear this stale registration fails and a “No such local endpoint is registered, clear
failed.” error message is generated.
Conditions: This symptom is observed in the following topology:
CUCM H.225 trunks register to a gatekeeper (GK) cluster. Gatekeeper 1 (GK1) and gatekeeper 2
(GK2) are members of the GK cluster. The CUCM registers first to GK1, then fails over to GK2.
This registration at GK2 sends an alternate registration to GK1. However, because of network issues,
the unregistered indication does not reach GK1.
