    Abstract: A telephony call-waiting system for clients having a computer (112) with a video display unit (PC/VDU) and a public-switched telephony network (PSTN) telephone (111) connected to the PSTN (151) by a single line (150), keeps a status indication of the client's Internet connection status and, during periods of time the PC/VDU is connected to the Internet (101), alerts the clients by an alert signal over the Internet connection of any waiting PSTN calls. In a preferred embodiment the client's PC/VDU is adapted to provide an audio and/or visual alert event when an alert signal is received, and to provide for a user-initiated response to an alert, accepting or rejecting a call. In the event a call is accepted, provision is made for connecting the accepted call to the client's PC/VDU as an IP call. In some embodiments several calls may be dealt with at the PC/VDU, and features are provided such as caller-ID on the client's VDU. Several ways of accomplishing the callwaiting system are taught.
