[cisco-voip] Block call based on ANI and DNIS at the same time

[Norton, Mike]

This is the sort of problem where a technical solution really, really is not a very good solution, because it's not even a technical problem in the first place. Trying to force a technical solution onto a non-technical problem tends to, at best, result in something non-scalable and "fragile," as Ryan put it.

Is it really worth having an overcomplicated non-standard dial plan that nobody except you can even understand, and completely breaks for the entire organization every time the slightest minor error in configuration is made, just because one staff member was careless about dropping their business card in tradeshow draws (or whatever)?

If the caller is a legitimate vendor and they want to keep your business, a strongly-worded letter or two telling them to get their act together, delivered by overnight courier, would be a much more elegant solution. Failing that, I'd advise the callee to be a big boy/girl and suck it up just like every other person in the world who has a phone.

"Problems" like this remind me why I'm glad to not work in business. My sympathies to those who do. :-)

Hi all!

I am trying to figure out if it is possible to block calls from an ANI but only to a specific DNIS while allowing calls to other extensions to proceed from that ANI?

The scenario:
800-555-5555<tel:800-555-5555> calls our extension 1000. However, extension 1000 is an executive and shouldn't be getting those calls. 800-555-5555<tel:800-555-5555> is a valid number associated with a vendor of ours, and calls to other internal numbers are OK, but not to extn. 1000.

I am familiar with the "Route Next Hop By Calling Party Number<https://supportforums.cisco.com/document/71966/blocking-calls-based-calling-party-id>" and have tested that functionality but it seems to apply to all extensions and I don't see a way to filter based on called extension as well as ANI at the same time.

We are using CUCM 9.x with an MGCP gateway.

We have also asked the vendor not to call extn 1000 but it is taking them a while to remove that number from their autodialers I guess as calls are still arriving.

Thanks for any ideas

Mike S.
