Abstract:
A method of delivering an on-hook FSK-modulated Caller ID message from a CO to a telephone comprising the steps of:providing an incompatible network coupled between the CO and the telephone wherein a first network component of the incompatible network couples to the CO and a second network component of the incompatible network couples to the telephone; establishing a communication link through the incompatible network between the first network component and the second network component; communicating falsely to a CO that the second network component has begun a first ring cycle at the telephone after said establishing step has been accomplished; transmitting an FSK-modulated Caller ID message from the CO to the first network component; converting the FSK-modulated Caller ID message into an out-of-band message; communicating the out-of-band message through the communication link to the second network component; converting the out-of-band message at the second network component into the FSK-modulated Caller ID message; and transmitting the FSK-modulated Caller ID message from the second network component to the telephone during a silent interval.
