Inter cluster calling

[sonisdreams]

Hi ,

We have 4 CUCM (7.x) cluster for four regions. Each cluster has 1 Pub. And 3 Subs. I want to enable inter cluster calling because all regions are at our MPLS Network.

Kindly suggest what to do to enable calling across 4 regions.

Regards,

Soni

Hi,

this is the "Contact Center" forum, your post would get better exposure in the "IP Telephony" section, but anyway. The easiest thing would be to set up intercluster trunks between clusters, and perhaps use Locations-based CAC to control the number of calls.

Or, a bit sophisticated approach: use a Gatekeeper (or a cluster of gatekeepers) to decide where to route the calls. You may also use Locations-based CAC or Gatekeeper CAC (or their combination).

Thanks Gergely for reply. I will post the same to IP Telephony section.

Well I am planing to create SIP trunk between the cluster and add route. will it solve this.

Hi,

yes, SIP is also an option.
