We generally use CUCM publisher IP/name while calling EM API but one of our customer told us that they have 2 dedicated CUCM subscribers for extension mobility feature. Can you please confirm which CUCM IP address should be assigned for EM API in this case?
If we are calling publisher API what will happen if publisher goes down. Do we need to call API with subscriber IP if publisher goes down.
Thanks & Regards,
The E/M API should work fine from any node (assuming all needed services are running). An application could certainly be able to use Pub/Sub as primary/backup for failover purposes.
