I have a customer with 1 main site and 3 branch sites. The CUCM is located at the main site together with the Voice Gateway.
I have seperated the 4 sites in to 4 different partitions, and created CSS based on these. the branch sites aer allowed to dial the DN's on the main site, but not the DN's on the other branch sites.
Now the customer asks me to configure the CUCM, so that brach site 1 is allowed to call 3 DN's on Branch site 2 - but ONLY these 3 DN's. How do I best configure that? As far as I am concerned, a DN can only be in 1 partition at the time...
