A telephone adaptively updates its speed dial memory. For example, the telephone updates the speed dial memory based on a calling history. An example of a calling history based update according to the invention is to add frequently called telephone numbers to the speed dial memory and to drop infrequently called telephone numbers from the speed dial memory. Another example is to order the telephone numbers in the speed dial memory based on the frequency with which they are called.

Apparatus and methods for adaptively, reliably, and accurately measuring the frequency of an alerting or other signaling tone. A tone detector measures the frequency of a tone (continuous or pulsed) with a high degree of accuracy (e.g., to within 1 part in 10,000). Two lower order or smaller DFTs measure the energy level in two separate but intersecting frequency ranges. A simple ratio is determined from the relative energy measured from discrete Fourier transforms relating to each of the two separate frequency ranges, and an actual measured frequency is determined.

According to one aspect of the invention, two lines are utilized to selectively forward calls based on caller ID data. Thus, according to one embodiment of the invention, a method of connecting a calling party to a called party includes the steps of a customer premise equipment (CPE) receiving an incoming call from the calling party on a first line, the CPE evaluating caller ID data associated with the incoming call, and the CPE placing an outgoing call to the called party on a second line based on the caller ID data. In another embodiment, a CPE includes a first line, a second line, and a calling unit adapted to place an outgoing call on the second line based on caller ID data associated with an incoming call received on the first line. In yet another embodiment, a method of forwarding a call includes the steps of receiving the call on a first line, selectively calling a forwarding number on a second line based on caller ID data associated with the received call, and coupling the first line to the second line.

A method of using an intercom on a cordless telephone during an active call. The active call is put on hold while the intercom is in use. Once the call is re-activated, the intercom is shut off. This system may be designed for a cordless telephone with one handset or a plurality of handsets.

A wireless piconet network device includes a GPS receiver to determine and provide earth coordinates to a gatekeeper of a wireless network so as to provide a level of security to wireless networks which requires accessing wireless devices to be within predefined boundary coordinates. The automatic restriction of access to a wireless network (e.g., a wireless local area network (LAN) such as a piconet network) by requiring a wireless network device to provide earth coordinates (e.g., GPS location information) as part of an establishment or maintenance of a connection to a wireless network, independent of a range of communication of any device in the wireless network. A wireless piconet network device outside of predetermined earth coordinates of a secured area (e.g., a building, a room in a building, a desk in a room in a building, etc.) may be denied access to resources on the wireless network, and/or required to provide additional authorization information so as to confirm authorized secured status of the entering wireless device.

In one embodiment according to the invention, a cordless telephone comprises a base unit and a handset. An RF link between the base unit and the handset is adapted for use during a telephone conversation and for use as an intercom. When in an intercom mode, an incoming call is handled in a manner that does not automatically terminate the intercom mode in response to the incoming call. For example, call related information associated with the incoming call may be analyzed, and a decision to terminate the intercom mode may be based on the call related information. In an alternative example, call related information may be transmitted by the base unit to the handset, and the handset may be adapted to display at least a portion of the call related information, so that a user may elect whether to respond to the incoming call or to maintain the intercom. In another alternative embodiment according to the invention, a method of handling an incoming call in a cordless telephone that is in an intercom mode, includes the steps of analyzing call related information associated with the incoming call, and deciding whether to terminate the intercom mode based on the call related information.

An Audio Caller ID service is provided which permits the calling party to speak a real time audio message that can be received and played by the called party's Caller ID equipment while his telephone equipment remains in the “on-hook” state. A calling party which has Audio Caller ID (ACID) service would speak a short audio message before dialing the called party. That message is converted to digital form, optionally compressed, and transferred to the called party in a manner similar to conventional Caller ID information. The called party's Caller ID equipment operates in the conventional manner, except that the received Audio Caller ID signal is recognized as an audio signal. At the site of the called party, a decoder is provided to convert the digital signal to an analog audio signal, and this analog signal is provided to a speaker, which plays back the calling party's audio message.

The present invention provides a device for connecting a power supply to a rechargeable device, in which a detection unit is adapted to detect power levels of a battery to output a first signal when a low power level of the battery is detected, and a second signal when a sufficient power level of the battery is detected. A power control unit is adapted to receive the first and second signals, and to disconnect circuitry in the rechargeable device from the battery when the first signal is asserted, and to connect the circuitry in the rechargeable device to the battery when the second signal is asserted.
