load balance of DP to CUCM
When configuring H323 dial-peer towards CUCM Cluster (Pub and Sub), and using the same preference for both dial-peer, but the Hunt Option is set to 1, so that the gateway will load balance calls to CUCM Servers.
I think that in that case, when one CUCM will go down, the gateway will not re-route the calls to another CUCM, if the call is destined for dead CUCM server.
For backup functionality to work, the Preference command is necessary on dial-peers.
Can you please confirm this, as I cannot get to my lab now.
