I have a setup where I'm migrating from a 4.x to a 6.x cluster. The clusters have identical route plans (built from DNA), but for the 6.x cluster the ICT trunk has been added as a last option for the PSTN RL as no PRI's have been cut over to the new system. Calls work fine to the PSTN, passing over the ICT and out the 4.x cluster but the CLID shows private number. The PSTN RL on 4.x uses the external mask to set the CLID and it works fine for calls originating on that cluster, but it seems like it can't pull this info from the call since it originated on the other side of the ICT. Anyone have any thoughts or ideas of a workaround beside swinging over PRI's to locally handle the PSTN routes on the 6.x cluster?
