Re: [OSL | CCIE_Voice] MGCP failover and call preservation
Yes, using debug mgcp packet I see the gateway send a RSIP, the backup CUCM sends it's RQNT, I can then see the AUEP for each channel, and the corresponding AUCX for the active channel. A show ccm-manager shows it as registered to the backup. The call is eventually disconnected when the gateway sends a DLCX to call manager after about 15 seconds. I am testing by shuting down the primary cucm call manager service.

Re: [OSL | CCIE_Voice] MGCP failover and call preservation
Hi Matthew I'm going to test this to check if I can reproduce your fault but a few questions first: Can you confirm to us that your gateway re-registers successfully to the backup CUCM? After registering you should see and AUEP and AUCX coming from CUCM interrogating the calls the gateway preserved. Are you using debug mgcp packets to view these? So, if this is not happening maybe you have got something blocking communication there? How are you testing your failover? By stopping the service in CUCM or by a null route/ACL?

[OSL | CCIE_Voice] MGCP failover and call preservation
Not the question you might be thinking. It seems really basic, but I must be forgetting something. When I preserve a call to the PSTN, once mgcp has lost connectivity to the primary call manager, If I hang up the voip phone, the PSTN line does not hang up. I don't see UCM send anything to the MGCP gateway in my debugs and consequently a disconnect never get sent to the PRI. The call eventually disconnects due to timeout. This occurs whether the primary call agent comes back online or not. What am I missing? ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
