Methods of and systems for monitoring a first call connection while effecting the establishment of a second call connection










Image Number 13 for United States Patent #4399532.

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. The attendant then establishes a two-way connection between the attendant and the second-incoming call to be served by the PBX system (20). 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.
