Redundancy/failover is not occuring while E1 channels are out of service
Currently we have 2 x 3845 configured as H323 gateways which talk to Callmanager cluster.
Got Route group 1 and Route group 2 configured then associated both Route groups into a Route list.
Have a Route pattern e.g 0.! configured and referenced the Route list i created containing both RGs discard digits preDot on the Route group level instead of under the route pattern.
On one of the 3845-01 we have 2 x E1 PRI 60 channels out to the PSTN. The other 3845-02 we only have 1 x E1 PRI 30 channels.
Anyays when i force an outage on both the E1 PRIs on the 3845-01 e.g. shutting down the voice ports. I have this impression that when the H323 gateways send a H225/TCP message such as channel unavailable or a out of service message back to callmanager. Callmanager will then find that we lost H225 messages with 3845-01 and failover to 3845-02 router. I definitely know that if these gateways where configured for MGCP i can acheive what i wanted.
But in the past discussions on this forum people where able to get this to work with H323 no problems.
Is there something missing or misconfigured? could there be a service parameter on callmanager i can set, etc.
