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

[Ryan Huff]

I am NOT trying to intentionally plug my blog here; however this is a very good article that addresses your very query.

The only thing you would do, is modify slightly so that the technique only applied to a particular called number/pattern.

Hope this helps,

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.
