In this case, the "knob" that is used to block the call is the Route or Block this pattern option.

To do this, the DNIS or called number can be specified in a route pattern, then applied to the gateway. To block calls in the same manner at the Cisco CallManager level, use translation patterns.
Note: This method of blocking calls can only be accomplished based on the DNIS information (called party number) and not on the ANI (calling party number) information.
This sends the call nowhere, and the calling party receives a reorder tone. Give the x-lation pattern a CSS that has access to NOTHING. Then, the gateway in Cisco CallManager must be configured to have a Content Services Switch (CSS) with access to this x-lation pattern first, based on the x-lation pattern partition. This is accomplished through translation patterns in the Cisco CallManager configuration.Īn x-lation pattern in Cisco CallManager must be created to match the inbound DNIS information (called party number). If a Media Gateway Control Protocol (MGCP) gateway (controlled by Cisco CallManager) is used, the only way to block unwanted calls is based on the DNIS information.
