Blocking Certain numbers from calling my company

[dvanzee]

Does anyone know if it's possible to block certain numbers from calling into my company? Is there a way to block phone numbers?

[Jim Douglas]

If you are using MCGP, you cannot block numbers coming in. We had this same issue a few weeks ago and cannot do anything about it.

However, if you are using H.323, it is possible - Unfortunately, I do not know how to configure it.

Sorry - MGCP - my fingers got ahead of my thoughts.

I just did a little research and it appears that you can block numbers by creating a route pattern on the number and say "Block this pattern" Can someone comment on this?

[Jim Douglas]

Your Route Patterns that are setup to "Block This Pattern" will block outgoing calls from your company.

I have seen this response in the past as well, but it does not work this way. Route Pattern never does a match using the Calling Number. It only does a match using the Called Number, therefore you cannot block the call using Calling party number on CCM.

Only way to block a call using Calling Number is to use a H323 Gateway, where you can use a Calling Number as a match option.

Hope this helps

As already said you can ONLY block incoming calls per calling number using H.323, take a look to the following document:
