[cisco-voip] MGCP gateway not registering to Subscribers

[george.hendrix at l-3com.com]

That's odd that it's working on one and not the other.  I've always set the redundant hosts command with the secondary and tertiary CCM's.  The ccm call agent I always set to the first subscriber I want it to use, not the publisher.  I have 2 MGCP gateways (IOS 15) configured this way and they both are registered to the correct CCM and also show the list correctly .

What's the config of the mgcp gw that's working?

Bill, after some more detective work I have one gateway now functioning as follows:

ccm-manager redundant-host b.subscriber.com<http://c.subscriber.com/> c.subscriber.com<http://b.subscriber.com/>
mgcp call-agent a.subscriber.com<http://b.subscriber.com/> 2427 service-type mgcp version 0.1

The above is working on that particular gateway and is what we want to have. The running-config for the functional gateway is the same as another gateway having the originally described issue. I am now going through the "sh run all" for both gateways to try to find a difference in the config. I also have to try this gateway against all subs to see if maybe a.sub is okay and b.sub is not. I have a feeling all subs are okay as I do recall issues with a.sub on what I now know to be the problem gateways.

Keep 'em coming!

Good day, all,

We have a ucm8 cluster with a publisher and three subscribers. All of our gateways configured in 8.6.1 (3825s, 3925s) all register normally to the publisher but none will register to the subscribers. Hostnames are all correct. What should I be looking for? Here is a snippet of the mgcp config:

ccm-manager redundant-host b.subscriber.com<http://b.subscriber.com> c.subscriber.com<http://c.subscriber.com>
ccm-manager mgcp
no ccm-manager fax protocol cisco
ccm-manager music-on-hold
ccm-manager config server {IP address of Publisher}
ccm-manager config
!
mgcp
mgcp call-agent a.publisher.com<http://a.publisher.com> 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode nte-gw
mgcp rtp unreachable timeout 1000 action notify
mgcp package-capability rtp-package
mgcp package-capability sst-package
mgcp package-capability pre-package
no mgcp package-capability res-package
no mgcp package-capability fxr-package
no mgcp timer receive-rtcp
mgcp timer nse-response t38 250
mgcp sdp simple
mgcp fax rate 9600
mgcp fax t38 inhibit
mgcp bind control source-interface GigabitEthernet0/0
mgcp bind media source-interface GigabitEthernet0/0
!
mgcp profile default

Any help and points to the right direction are appreciated. Obviously, we want them to register to the subs and fail to another sub or the pub.

Thank you,
