I've a trouble with 2 call-manager in cluster that i don't know were to begin to fix it.
When a call from ISDN goes to the gateway, I've 2 dial-peer voice that forward that call to the callmanager; I used, as always, the preference 1 and preference 2 to set the target ccm1 and ccm2.
Disconnecting one ccm from the network I've seen:
A) if the callmanager disconnected is the one with preference 2, there are no problem.
B) if the callmanager I disconnect is the one associated with preference 1, the call is delayed of several seconds ( more than 15 ).
It seems like the dial-peer with the best preference wait a long timeout before to use the other.
Anyone had similar troubles ?
PS: from "debug voice dial-peer detail" i see the match for both dial-peer, then the calls "wait" 10-15 seconds, then goes to the preference 2 ccm.
I think you haven't set the H225 timeout correctly:
voice class h323 1
h225 timeout tcp establish 3
