Abstract
A method and apparatus for notifying a user of a call waiting while a telephone is on hold. A transmit signal path and a receive path between a central office line and transmitter and receiver elements in the telephone are muted to place a call on hold. A customer premise equipment alerting signal is received from the central office while the transmit signal path and receive path are muted. The receive path is un-muted after the customer premise equipment alerting signal is received and an audible message signal is generated and inserted into the receive path in response to the customer premise equipment alerting signal to notify a user that the customer premise equipment alerting signal has been received. The receive path is then re-muted.
