Intercluster trunk restrictions

[Yannick Vranckx]

Dear All,

Is there a restriction in creating an intercluster trunk between 2 call managers. I'm trying to simulate this in a lab environment where i have one Call manager version 10.5 connecting to a Call Manager 7.1.X to route some calls outside my lab CUCM to another one.

Do intercluster trunk need to match CUCM versions? i'm not really seeing any calls getting through across the trunk, in call manager 7 there seems to be no way to check the uptime of the trunk nor see if it's active. I'm using DNA tests to see if the call gets routed over de trunk and it does.

Kr,

Yannick Vranckx

No, you can have an ICT between different version, hopefully you're not using a SIP trunk, we only recommend that if all clusters are 8.6(2) and above, if you need to trunk with a lower CUCM version, use the old ICT non-GK controlled. Aside from that, the rest of the config is the same, RP, RL, RG, CSS, partitions, etc.
