Redundant call agent

I tried to configure redundant call agent with below configuration on the gateway (2951) but it fails:

ccm-manager redundant-host 192.168.50.11                           ---------------------------- Publisher

call-agent 192.168.50.12 2427 service-type mgcp version 0.1   ------------------------------Subscriber

Primery is Subscriber

Thanks,

Ali

Redundant call agent

I am trying to configure the Subscriber as the primery call agent and the Publisher as secondry. But the things work while the call agent is the Subscriber (primery), however when the subscriber goes down the Publisher doesn't take over (with above configuration in place).

Thanks,

Ali

Re: Redundant call agent

Hi

You mean that when the sub is down then the calls not working right?

From the ccm-manager file it looks that is registered ok with the pub

Not working incoming outgoings calls?

Re: Redundant call agent

Any calls through the gateway is not working (outside calls), only internal call is working.

Re: Redundant call agent

In the CUCM is registered the MGCP GW right?

Try no mgcp and mgcp in voice gateway

Debug mgcp packets in VG

Can you send the mgcp config in VG?

Is the PUB in the Call manager group fo
the device pool that the gateway is using ?

E.g.

CM-GROUP MYGROUP = SUB & PUB

Device Pool MGCP-GW
CM GROUP  --- MYGROUP

Re: Redundant call agent

From the output of your show ccm-manager it lookes like the pub is the one that is used as the call agent, not the sub.

sh ccm-manager
