Block ALL incoming calls to a certain DN

I want to block ALL incoming calls to a certain DN but I need to allow just one number to be able to reach that DN.

So to block all incoming calls I just put the DN in a different PT so that the Gateway CSS cannot reach it.

Now can anyone try to explain how I would go about letting just one number coming in the same gateway be able to reach that DN? I am using MGCP so the config needs to be CUCM based. I guess there must be a way to do it with Translation Patterns somehow?


Block ALL incoming calls to a certain DN

what CUCM version ar eyou using ?

if its 8.x or 8.5.x i beleiv eyou can do it using a new translation pattern that can look into the caling number

other than this CUCM can not look into the calling number and as you are using MGCP it wont be done unless you use H323 translation-profiles/rules

hope this help
