    Abstract: A voice over Internet Protocol (VoIP) positioning center (VPC) is implemented in configuration with support from a text-to-voice module, emergency routing database, and VoIP switching points (VSPs) to allow a public safety access point (PSAP) or other emergency center to effectively communicate the nature of an emergency alert notification and the area of notification to the VoIP positioning center (VPC). The inventive VPC in turn determines which phones (including wireless and/or VoIP phones) are currently in the area for notification, and reliably and quickly issues the required warning to all affected wireless and VoIP phones.

    Abstract: The present invention is related to methods and systems for reducing or canceling echoes during fax communications. In an embodiment, during a fax call, a first fax signal from a first fax device intended for a second fax device is detected. Based at least in part on detecting the first fax signal from the first fax device or on the termination of the first fax signal, an echo audio packet is muted, wherein the echo audio packet is at least partly the result of the first fax signal being transmitted over a network, the network including at least a data network.

    Abstract: A method and system for dynamic call type detection for circuit and packet-switched networks. A network endpoint, such as a gateway, will receive an incoming signal and make an examination of the signal to detect characteristics of the signal. Upon detection of a characteristic of the signal, the gateway will generate a data packet, identifying the characteristic, and send the packet to a receiving network endpoint. The initial gateway will continue to examine the incoming signal and continue to send packets identifying characteristics of the signal as more characteristics are detected. The receiving gateway may then begin reproducing the signal in part by generating a signal that has the characteristics as indicated by the data packets. Once the initial gateway no longer receives the incoming signal, and determines that an event has occurred, the gateway will send a packet to the receiving gateway to inform it of the event.

    Abstract: A method and apparatus for forwarding of fax calls to a messaging service are disclosed. For example, the method receives a call and rings one or more endpoint devices. The method detects an off-hook condition for the one or more endpoint devices and detects a fax tone in the call. The method then informs a network to forward the call towards a messaging service.

    Abstract: An IFAX IP telephone connects a call to an opposing IFAX IP telephone via the Internet, and executes a voice call process that exchanges voice packets with the connected opposing IFAX IP telephone. When transmitting an image data to the opposing IFAX IP telephone during the voice call to the same telephone, an IFAX packet is generated, the packet having the opposing IFAX IP telephone as the destination. The IFAX packet is transmitted, while prioritizing the voice packet transmission.

    Abstract: A method and system for far echo rejection for a fax modem control channel is disclosed for eliminating far echo signals during a fax transmission with a fax modem using a control channel and a primary channel for transmitting data. The far echo rejection may be achieved even if the fax modem standard utilized does not include far echo training. An echo detection control frame is transmitted during the initial fax transmission control channel communications. Far echo rejection can be achieved by monitoring for an echo of the sent echo detection control frame, measuring the detected echo level, recording the echo level, and rejecting signals below a threshold based upon the echo level. Signals at or above the echo threshold level are treated as fax signals while signals below the threshold level are assumed to be far echoes.
