Multi cluster distributed with GK scenario

Here is the scenario:

5 sites located in AU, US, UK, DE. Three sites have CME and two sites have CM.(6.1(1)

Each site has his own IOS gateway with connectivity to PSTN.

Question:

I can either create trunks between callmanagers (GK controlled) OR just send calls through gateways (GTWYs are connected to GK)

What advantage do I gain by creating GK controlled trunks between callmanagers Vs. just sending the calls trhough H.323 gateways?

thanks,

rdianat

Re: Multi cluster distributed with GK scenario

You can configure H.323 gateways either with gatekeeper control or locally as gateways. Sometimes an anonymous H.323 device, a device that is not known to Cisco Unified Communications Manager, tries to initiate (send or receive) calls with Cisco Unified Communications Manager. This anonymous device could be a Cisco IOS product (such as a gateway) or any third-party H.323 device.
