Is it possible to reject or translate unknown inbound caller-id on a h.323 PRI gateway. I have written voice translation rules for known caller-ids but have been unable to find any way to block unknown calls.
I don't see any way at all to do this using translation-rules or anything in CallManager. Only possible way would be to filter inbound calls through an IVR script which could do it but that wouldn't be a good idea at all.
