A second-incoming call appears at an attendant facility (34) within a PBX system (20) while the attendant is awaiting a response on a first-incoming call. The attendant activates an overlap button (35) to facilitate the conversion of the first-incoming call into a listen-only connection.

Thereafter, the attendant monitors the first-incoming call on a listen-only basis while simultaneously serving the second-incoming call associated with the two-way connection.       Recently Added Patents Programmable memory repair scheme System and method for layer-wise proton beam current variation Position detecting device having opposite-phase magnetic-field generating coil, medical device guiding system, position detecting method, and medical device guiding method Process for the preparation of syngas and methanol from organic wastes Neutron detection based on induced charges Substrate processing system and group management system Side wall pore sealing for low-k dielectrics   Randomly Featured Patents Indolecarboxylic acid derivative having PGD2 receptor antagonistic activity Fuel atomizers Multiangle, multiwavelength particle characterization system and method System managed logging of objects to speed recovery processing Method and apparatus for direct control of the inter-area dynamics in large electric power systems Nickel base coating alloy Protective barrier coating composition Harmonic multiplexer Methods, systems, computer program products, and data structures for limiting the dissemination of electronic email Process for disposing of decoy flare material © 2006-2008 PatentGenius.
