Solved: Inter-Cluster-Trunk or SIP Trunk between CUCM 7.1 and CUCM 12.X for Inter-Cluster Calling.

Hello Guys,

Can we configure Inter-Cluster-Trunk or SIP Trunk between CUCM 7.1 and CUCM 12.X for Inter-Cluster Calling.

Is it supported ?

SIP trunks are only recommended when CUCM releases are 8.6+, anything below should use an ICT

It should work just fine, it was obviously never tested as 7.x is long EOS/EOL.
