Computer program products, methods, systems, apparatus, and computing entities are provided for location-based call control. In one embodiment, call control rules for an outbound call can be determined/identified based on the location of the mobile device. The call control rules direct the outbound call to different numbers and/or different applications.

In an automatic telephone call transfer apparatus in an Internet connection mode, an initial value setting portion sets a telephone number of an exchange of a telephone office which will perform a call transfer, a telephone number of an ISP to be subject to the call transfer, and an automatic/manual mode. An automatic call transfer setting/canceling portion transmits data corresponding to the telephone number of an exchange of a telephone office set at the initial value setting portion, call transfer request data, and the telephone number of the ISP to be subject to the call transfer at the connection of an Internet service, and at the termination of the Internet service, transmits the number of the exchange of the telephone number set at the initial value setting portion and data for canceling the call transfer. A modem is connected to a communication line. A telephone connection portion makes a telephone call at the telephone number of the exchange of the telephone office received at the connection and termination of the Internet. A first switch is connected to the telephone connection portion at the connection and termination of the Internet to transmit the data from the automatic call transfer setting/canceling portion to the exchange of the telephone office through a network and then connects to the modem. A voice conversion portion converts analog voice signals to digital signals to perform modulation and compresses and converts the signals into packet data when the voice signals are transmitted, and restores the packet data into analog signals when the voice signal is received. A second switch is connected a telephone to the voice conversion portion in the Internet connection mode and to telephone connection portion in the other mode.

A telephony call-waiting system for clients having a computer with a video display unit (PC/VDU) and a public-switched telephony network (PSTN) telephone connected to the PSTN by a single line, keeps a status indication of the client's Internet connection status and, during periods of time the PC/VDU is connected to the Internet, alerts the client 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 call-waiting system are taught.

The present invention provides a selective automatic call forwarding method and system. In response to a request from a subscriber for the selective call forwarding service, a selective call forwarding service record is created for the subscriber which includes the subscriber's telephone number, a "trigger" telephone number, and a call forwarding number associated with the trigger number. An example of the trigger number might be the subscriber's Internet access telephone number. An example of the call forwarding number might be the subscriber's mobile telephone number. A determination is made, e.g., a flag is set in the subscriber record, whenever the subscriber is engaged in a communication initiated to the trigger number. Thereafter, incoming calls directed to the subscriber are automatically forwarded to the call forwarding number. However, if the subscriber is currently engaged in a communication with a telephone number other than the trigger number registered in the subscriber's call forwarding service record, incoming calls are handled in a manner other than forwarding the incoming call to the call forwarding number. Such other procedures might include, for example, generation of a busy signal, execution of a call waiting service, or execution of a call completion service.

A method and system are provided for preventing data loss in a VoIP system. In particular, during a VoIP call, it is determined whether incoming ringing on a POTS line causes an unacceptable level of signal loss or errors. If so, for subsequent VoIP calls, the CO handling calls to the POTS line is instructed to either answer each call with a busy signal or automatically forward calls to the POTS line to the VoIP line or other selected telephone. Calling returns to normal upon ending of the VoIP call. In this manner, incoming ringing on the POTS line does not result in call dropping or lengthy retraining processes.

A telecommunications system and method is disclosed for providing interoperability between a cellular system's direct access to the Internet and the telephony service provided by the Public Switched Telephone Network (PSTN), in order to allow a mobile subscriber to receive calls from the PSTN while engaged in data communication, for example, over the Internet. When a Mobile Station (MS) has an active connection to a server or router running Internet Protocol, an incoming PSTN call can be forwarded to a voice gateway within the serving Mobile Switching Center/Visitor Location Register (MSC/VLR), which transforms the call to an Internet phone call. During the direct access connection to the Internet, the MS can signal specific information, using, e.g., a prefix, to activate the call forwarding to voice gateway feature.

Systems and methods allow an administrator of a conference call bridge to control who is admitted to the conference call bridge. The systems and methods also allow the administrator to identify a new individual who will become the administrator of the conference call bridge when a triggering event occurs. The systems and methods also allow an administrator to identify a new endpoint device from which valid control commands can be received.
