Intercluster Trunk ICT call between 6.x cluster and 9.x cluster - Hold, Transfer, etc do not work
Example: Call comes in from PSTN to gateway registered to 6.x cluster. IP PHone answers the call, transfers call over intercluster trunk (ICT) to IP Phone registered to 9.x cluster. IP Phone on 9.x cluster cannot invoke the call hold, or call transfer or any softkey, etc features for that active call.
I know this thread is a little old but I had this same issue. The fix was resetting the MTP that the ICT (Inter-Cluster Trunk) uses on the 9.x side of the call (the end that couldn't put the call on hold, xfer, etc.)
