An exemplary system includes: (1) a switching network having switches for routing telephone calls; (2) a signaling network coupling switches in the switching network to one another for routing a calling party number and a called party number associated with a telephone call; and (3) a platform coupled to the switching network. The platform stores a calling party number and a called party number received from the switching network corresponding to a telephone call in which the calling party number encountered a ring-no-answer condition and requested an automatic call-back. A processor in the platform detects a subsequent telephone call involving the called party number and, at the conclusion of the subsequent telephone call, initiates the automatic call-back to the calling party number. Upon completing the automatic call-back to the calling party number, the platform transmits a pre-recorded announcement to the calling party number via the switching network indicating that the platform will attempt to complete a telephone call to the called party number in satisfaction of the calling party number's outstanding automatic call-back request. Upon completing the telephone call to the called party number, the platform merges the telephone call to the calling party number with that to the called party number.Field of SearchSignalling path distinct from trunk (e.g., CCIS) | |
