Cisco Call Manager integration with CME with Gatekeeper

Hi All,

I am integrating CME with CUCM by using gatekeeper. My Network tropology is

CME+PSTN Gateway (Router 3845)< ------------------> Gatekeeper + Gateway at CCM site (Router 2901) <...............> CCM 8.

Note: Please see the attachment.

I am very new to IPT. Could you please let me how I will do the configuration in Gatekeeper. Please let me know if any doc available..

Regards,

Nirmal

Nirmal,

Not sure if you have stumbled across this one yet:

To begin it's a very good one.

The part that may give you the most trouble is CUCM because it will not register the alias number. Rather you need to route based on tech prefix and zone prefix. You can check out this one as well.

Nirmal,

In this case the first step will be register the CME gateway and the CUCM to the gatekeeper with the proper prefixes for both devices, that is the key to get this configuration working in the proper way.

I strongly recommend you to get familiar with the gatekeeper technology and configuration before anything else.

These are very good documents that explains how the gatekeeper works and the configuration to register the gateway and the CUCM
