Setting Up Dial Peer Call Blocking

You can set up incoming call blocking based on the call number after the two-stage dialing or overlap dialing is completed.

Use a reject rule in the translation rule and apply these rules for calling number, called number, or redirect called number of an incoming call.

Call blocking parameters must be configured on outbound dial peers.

Prerequisites:

You can set up call blocking for both ingress and egress routes.

Use this procedure to set up call blocking attributes for a route.

To configure a voice source group for call blocking based on an IP access list, refer to Adding a Voice Source Group.

Procedure

  1. Modify an existing egress or ingress route or create a new route.

  2. Assign a call blocking profile to the route. (See prerequisites above.)

  3. Assign the translation profile with reject rules to the route.

  4. Add the disconnect cause to the call blocking profile.
