Hello All,


Is there a way to configure the new ISR G2 routers as an MGCP gateway under CallManager 4.x (specifically 4.2(3))?  There are no options for the 2900 or 3900 models available for selection.  Many thanks in advance for any assistance provided.

The MGCP packets are formatted in a special way for each model, most likely they're quite similar for those models.

I'm glad it works, but bear in mind we still need to look at the Cisco support policies so that's not something we can provide support if you run into problems.

In my experience, usually customers don't like the phrase "might work but we won't support you" and with a doc that explains compatibility they always go for the upgrade.

No, there is no way. You need to upgrade.

Either to 6.1(5), 7.1(3) or 8.

The only other option is to use H323, no way using MGCP.

Fellow Networkers,


A followup to the original issue.  Just for the sake of trying, I configured an MGCP gateway as a 2851 for the 2921 and it worked flawlessly.  I guess the key is to make sure you use the exact port number for your mods.  Thanks again for the assistance.

Thanks for the documentation, Java.  I will use it to convince the customer they need to upgrade.  Have a great day!
