Restricting Callers from the Outside

[marion.barnes]

Hello,

I would like to know if their's a way to restrict a caller from the outside from calling a directory number in our voice network. We are using CCM 4.2(3) with MGCP gateways.

This might be what you need but it requires H323 gateways

Create a calling search space for the gateway that includes 2 partitions:

Outside-blocked

System

In the "Outside-blocked" place translation patterns that block the DN's you don't want called.

And the "System" partition is your normal existing partition for DID-reachable DN's.

So, I can create this Outside-blocked CSS and put a DN that I don't want called by a certain number. Or does this config block any calls from coming into that DN.

[Jaime Valencia]

that config will block ALL the calls to that DN coming in from that gateway
