Gateway Failover with CCM 4 1 3b


I am having issues with gateway redundancy on CCM 4-1-3b. Basically when the Primary route group gateway fails, the backup gateway does not work. You can not make external calls out of this gateway unless you change the priority of the gateways in the route group manually. The only other time it failsover is if ip connectivity fails between the primary gateway and the CCM. Has anyone had any issues like this or is there a bug with this version of CCM? Failover with RG/RL should be a basic feature with CCM?

Are the gateways associated to CCM using H323 or MGCP?

Hi Derek,

CCM regards H323 gateways as a black hole. CCM does not have the ability see the busy/fail status of the H323 ports. As you said, the only way CCM would switch to the second gateway, in the Route List, would be if IP connectivity was lost.

I would recommend that you additionally configuring outbound VOIP dial-peers (with a higher preference value) to forward the call from your first gateway to your second gateway when the first gateway is up and, for whatever reason, the outward ports are busy or down.
