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.

Claims

1. A method for monitoring a first party under surveillance, comprising the steps of:

(a) detecting access to telecommunications equipment corresponding to the first party;

(b) routing a telephone call between the first party and a second party via a bridge;

(c) automatically generating a paging message to a third party to alert the third party about the access, wherein the paging message identifies a telephone number corresponding to the bridge;

(d) receiving a telephone call from the third party to be connected to the bridge; and

(e) connecting the telephone call from the third party to the bridge to enable the third party to hear the telephone call between the first and second parties.

2. The invention of claim 1, wherein:

step (a) comprises the step of detecting an incoming telephone call from the second party to a telephone of the first party; and

step (b) comprises the step of routing the incoming call to the telephone of the first party via the bridge.

3. The invention of claim 1, wherein:

step (a) comprises the step of detecting an outgoing telephone call from a telephone of the first party to the second party; and

step (b) comprises the step of routing the outgoing call to the second party via the bridge.

4. The invention of claim 1, wherein step (a) comprises the step of detecting an incoming paging message from the second party to a pager of the first party.

5. The invention of claim, 4 wherein:

step (a) further comprises the step of detecting an outgoing call from the first party; and

step (b) comprises the step of routing the outgoing call via the bridge.

6. The invention of claim 5, wherein the outgoing call from the first party is a calling card call and step (a) further comprises the step of detecting the number corresponding to the calling card of the first party.

7. The invention of claim 5 wherein the outgoing call is routed via the bridge if the outgoing call is placed within a specified time period after the incoming paging message from the second party to the pager of the first party.
