This helps a lot except I've taken look at our gateways and they are indeed MGCP :( So that said, I will do some more research on my part but would you know what it would take to switch from MGCP to H.323?

Thanks

Hi Julien,

This would be a very complicated (but not impossible) change due to the way H.323 is configured.

Adding a Cisco IOS H.323 Gateway

Follow these procedures to add a Cisco IOS H.323 gateway to Cisco CallManager.

Before You Begin

Before configuring a Cisco IOS H.323 gateway for use with Cisco CallManager, you must configure the gateway by using the Cisco IOS command-line interface (CLI). Compared to MGCP gateways, H.323 gateways require more configuration on the gateway because the gateway must maintain the dial plan and route pattern.

I might be tempted to speak with your service provider to see what they can do before I went this route :)

Hope this helps!

Rob
