I have create a route group to include two H.323 gateway (3845 router) for redundancy.The CUCM version is 5.1.
G1 and G2 added in the route group with "TopDown" distribution algorithm. When i dial outgoing call, it would go through the G1.
I have perfomed test to shutdown the G1 to simulate the router down or unreachable case, the outgoing call should go through the G2.
However, i found there would be long idle time before the outgoing call got succeed by G2.
It seem that the CUCM have try reach the G1 for outgoingn call and keep trying until the pre-configured timeout value meet, so this call would go for G2.
So, i would like to know where i could configure this timeout value to speed up the phone call process in case the first router down in route group.
