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.
