摘要： A switch-adjunct integration device uses multiple line appearances of one or more digital telephone lines to gather information on calls destined for an adjunct voice-mail system, to transfer the calls to analog phone lines leading to the voice-mail system, and to detect call completions. Call completion is detected by bridging some of the line appearances to the analog phone lines and monitoring the bridged line appearances for call status reported thereon by the switch. Call-related information, including call completion, is reported from the integration device to the voice mail system over a control link. The analog phone lines are connected to the voice mail system through switch relays on the integration device. The integration device momentarily opens a relay when it detects call completion on the connected analog line to further enhance call-completion signaling.
