Blocking Calls Inbound - ??

Hello:

Is there a way to block calls inbound on the gateway router (coming in via the Pri)coming into an ip phone?

Or is this something that needs to be configured in the CCM for that particular phone.

Trying to block some 1-800 numbers from calling into an ip phone.

Thanks.

For H.323 you can use number translation, for MGCP I do not believe blocking is as easy, if possible at all. Tony Huynh provided this link in a previous post - thanks to Tony for the info.

Thank you, much.

So based on this: I am thinking of the following configuration:

#voice translation-rule 1

#rule 1 reject /1800*/

#voice translation-profile Block_1800

#translate calling 1

#dial-peer voice 22 pots

#call-block translation-profile incoming Block_1800

#call-block disconnect cause incoming call-reject incoming called-number

#port 1/0:23

#end

Would this work to block any 1800 number from calling into the IP Phone?

Thank you.

Niraj:

What you have looks like it will work. Apply to all ports with inbound PSTN access. Remember that telcos may not present the prefixed 1 on inbound DNIS and ANI.
