I've the following scenario: 2 CCM clusters connected via an Intercluster Trunk not GK controlled.
One Cluster is versione 3.3 and the other 7.1.
For IP extensions migration reason I need to have a RP XXXX pointing from one cluster to the other, because extensions still on the old cluster needs to be able to call extensions on the newer one. BUT this create calls loop IF an IP phone registered on the old cluster calls an unregistered ip phone. The call started to bounce from the old cluster to the new (where unregistered phone are forwarded to the old cluster) and this is the problem.
I was looking for a way to limit this scenario; I tried block offnet to offnet calls but it doesn't work. Do you have any suggestions (maybe limiting the maximum forwarding hops?)?
