Abstract

Method and system for delivering a message over a telecommunications network to a recipient comprising transmitting a message over the telecommunications network to the recipient when a predetermined energy/silence condition is detected, performing echo cancellation on a signal communicated from the telecommunications network, and monitoring the signal to detect the energy/silence condition.

Claims

1. A system for delivering a message over a communications network to a recipient, comprising:

a message player for delivering a message to a recipient over a communications network, wherein the message player waits to deliver the message until a predetermined initiating silence condition is met, initially delivers the message upon detection of a predetermined initiating silence condition and the message player continues to deliver the message while a second silence condition is detected;

a detector for monitoring a received signal from the communications network, wherein the detector detects the initial silence condition and the second silence condition and communicates with the message player; and

an echo canceller communicating with the detector, message player, and communications network, wherein the echo canceller enables detected of energy transmitted by the recipient over the received signal.

2. The system of claim 1, wherein the detector is a speech detector.

3. The system of claim 1, wherein the detector is an energy detector.

4. The system of claim 1, further comprising a call classifier for detecting an answer supervision condition, and wherein the detector is activated when answer supervision is detected.

5. The system of claim 1, further comprising a service controller for retrieving a telephone number from a recipient database and transmitting the telephone number to the communication network.

6. The system of claim 1, further comprising a message database linked to the message player for storing a pre-recorded message for transmission over the communications network.

7. The system of claim 6, further comprising service controller for retrieving the message from the message database and transmitting the message to the message player.

8. A method for delivering a message over a communications network to a recipient, the method comprising:

using a message player for delivering a message to a recipient;

waiting to deliver the message until a predetermined initiating silence condition is met;

initially delivering the message upon detection of a predetermined initiating silence condition; and

continuing to deliver the message while a second silence condition is detected;

using a detector for monitoring a received signal from the communications network;

detecting the initial silence condition and the second silence condition; and

communicating with the message player, and

using an echo canceller communicating with the detector, message player; and

communication network;

detecting energy transmitted by the recipient over the received signal.
