Inter-cluster trunk(Non gatekeeper controlled) between 7.1.5 to 4.1.2

Unanswered Question
Aug 10th, 2012

Hi all,

I have configured  ICT(Non gatekeeper controlled) between call manager cluster  7.1.5 <--> 4.1.2. But could not able to establish calls between these cluster .After reviewing the logs looks like ICT not yet established.

Can someone guide me on compatibility for ICT(Non gatekeeper controlled) between call manager cluster  7.1.5 <--> 4.1.2 ?

They are definitely compatible.  How many servers do you have on each side? Are all servers referenced in the trunks?

Is there a firewall between the clusters?

Chris,

In each cluster we have 5 servers include PUB, This ICT is pointed to two subscribers. I'm not sure about firewall if so.. could you please share the ports used for ICT ?,so I can check the network connectivity between these cluster.(ping and tracert works fine).

You need to ensure that the servers you are pointing to match the servers assigned to the CM Group that is referenced by the device pool assigned to the ICT on the other side.

So, cluster A has server 1,2,3,4,5

cluster B has servers 6,7,8,9,10

ICT on cluster A can only point to 3 servers, i.e. 6,7,8

ICT on cluster B has DP--> CM group with servers 6,7,8 listed and it points to servers 1,2,3 which are similarly assigned on the other side.

I belive this is nicely described in SRND doc.

HTH,

Chris
