SIP Trunk Between Callmanager Clusters

[thefindjack]

Is it possible to create a SIP trunk between CallManager v8.5.1 and v4.1 for 4 digit extension dialing between companies?  Does anybody have any good writeup on how this is done or a pointer in the right direction?

Thanks!

Hello,

Yes you can do that , it is easy , but since you are using two cisco clusters , it is easier and less using resources to use intercluster trunk.
