A method of supporting a mid-call hand-off feature () is provided in a telecommunications network (). The method includes: connecting a first call through a first switching facility () of the telecommunications network () such that a first party served by the first switching facility () and a second party are participating in the call; making a decision to invoke the mid-call hand-off feature (); placing a second call from the first switching facility () to a designated telephone number; and, connecting the second party to the second call.

Mid-call hand-off between end user terminals

A method of supporting a mid-call hand-off feature () is provided in a telecommunications network (). The method includes: connecting a first call through a first switching facility () of the telecommunications network (), the first call being connected between a first party served by the first switching facility () and a second party; receiving a second call at the first switching facility () for the first party while the first party is still connected to the first call; determining where the second call originated from; and, selectively connecting the second party to the second call in response to the determined origin of the second call.

Mid-call hand-offs in telecommunication networks

A method of establishing a call over a Public Switched Telephone Network (PSTN) is provided. The PSTN operatively connected to an End Office (EO) serving a calling party's Consumer Premises Equipment (CPE). The method includes: receiving at a network element of the PSTN a message requesting establishment of the call over the PSTN, the message being received over a packet-switched network and identifying the calling party's CPE from which the call is to be placed; and, notifying the EO serving the calling party's CPE of the request for establishment of the call such that the EO treats the call as a terminating call as opposed to an originating call.

System and method for establishing PSTN calls via an IP request

A method is provided for routing an emergency call from Customer Premises Equipment (CPE) to a Public Safety Answering Point (PSAP). The method includes: establishing a session over a packet-switched network () between a CPE () and a network node (), such that the CPE () accesses a Public Switched Telephone Network (PSTN) () from the network node () via a telecommunications switch () associated with a first PSAP () serving a geographic region () different than where the CPE () is currently located; identifying a telephone number for a second PSAP () serving the geographic region () in which the CPE () is located; and, substituting the identified telephone number for a dialed telephone number when the dialed telephone number is indicative of an emergency call.

System for routing remote VoIP emergency calls

A method of processing half-calls each having opposing first and second ends is provided within a telecommunications network. Each of the half-calls is either an originating half-call terminated at the first end thereof by calling consumer premises equipment (CPE) or a terminating half-call terminated at the first end thereof by called CPE, wherein an associated pair of half-calls connected at their second ends including both an originating and terminating half-call completes a call connecting the CPE terminating the respective first ends of the half-calls that form the pair. The method includes: applying identifiers to originating half-calls such that the originating half-calls are distinctly identifiable thereby with respect to one another, the identifiers thereafter accompanying terminating half-calls that form associated pairs of half-calls together with the originating half-calls to which the identifiers were applied; and, examining terminating half-calls to detect the identifiers such that upon detection of the identifiers the terminating half-calls accompanying the detected identifiers and the originating half-calls to which the identifier were applied are recognized as associated pairs of half-calls.

Audio watermarking for call identification in a telecommunications network

A system that implements the display of the well-recognized MLPP keypad generated by a computer-based application adaptable for any authorized user. In one embodiment in accordance with the present invention, a system is provided for emulating an MLPP telephone. The exemplary system comprises a data entry portion that accepts telephone call initiation information, including MLPP priority information, from a user, and an information display portion that displays information relating to the data entry portion. In one form of the invention, the data entry portion comprises a visual representation, on a display device, of an MLPP telephone keypad, and a data input device. The visual representation, on a display device, may be a visual representation on a video display terminal associated with a personal computer.

MLPP telephone emulation

A method of provisioning a gateway () is provided in a telecommunications network including a circuit-switched network () and a packet-switched network (). The gateway () bridges calls between the circuit-switched network () and the packet-switched network (). The method includes: receiving a registration message from consumer premises equipment (CPE) (), the message including an address for the CPE () on the packet-switched network (); determining a directory number (DN) for the CPE (); placing a probe call to the determined DN over the circuit-switched network (); receiving a call from the circuit-switched network (), the call being terminated at a call reference value (CRV); recognizing the received call received from the circuit-switched network () as the probe call; capturing the CRV at which the probe call is terminated; and, associating the captured CRV with the address for the CPE ().

Auto-provisioning for a voice over IP gateway

A method of detecting a user's presence at a workstation is provided. The workstation includes a computer () having an operating system () that has an interface for communicating with a screen saver (). The interface provides for screen saver communications intended to selectively result in screen saver activation and screen saver deactivation. The method includes: detecting the screen saver communications; determining that the user is not present at the workstation when the detected communications are intended to result in screen saver activation; and, determining that the user is present at the workstation when the detected communications are intended to result in screen saver deactivation.
