Dual-alerting paging system and monitoring of return call

Abstract

A technique for monitoring the calls placed to the telephone number associated with the party under surveillance. When a call to the telephone number associated with party under surveillance is placed, the call is routed via an assigned meet-me bridge, and a third party is provided with the unique telephone number of the meet-me bridge via a pager. When the third party places a call to the assigned meet-me bridge, the incoming call to the party under surveillance and the call by the third party are bridged. Thereon, the third party is placed on mute and the third party may silently listen to the conversation between the caller and the called party. When a call (i.e., a page) to a telephone number associated with a pager of the party under surveillance is received, a third party is alerted. Also, in response to the page, when the party under surveillance uses a specific calling card to place a return call, the return call is routed via a meet-me bridge having a unique number, and the third party is provided with this unique number. When the third party places a call to this unique number, that call is routed to the assigned meet-me bridge, and the return call and the call by the third party are bridged. Thereon, the third party is placed on mute and the third party may listen to the return call conversation.
