How to Configure CUCM for Connection Between Nodes (through site to site vpn)

Hi All,

 

Im trying to find out the best approach to connect

One cucm cluster (with one pub/one sub) with 2 other islands  which also have one subscriber

This needs to be done in a site to site vpn configuration.

 

Also i need to know what the requirements are for making this all possible.

Latency etc etc

So, are you asking how to do CoW??

Or simply how to configure a SIP trunk between two clusters?

You could configure a pair of expressways, and have those islands connect over the internet, without a VPN.

 

Most companies I've seen have an MPLS circuit between locations.

 

The other option is to have a site to site vpn between your main site and each island.  You'll be at the mercy of the internet for latency, etc, but it should work.  200 ms latency is a number I've seen thrown around.  The less latency the better though.
