Abstract: This invention relates to a communication system using an internet protocol (IP) address. Subscriber terminals have the same subscriber identification and different IP addresses. A server establishes a connection between the terminals via the network. A service system has a table including the subscriber identification information and the IP addresses of the subscriber terminals. When a connection request is made by a subscriber terminal to the group of subscriber terminals while a connection between one subscriber terminals of the group and another subscriber terminal is established, the service system detects an unused IP address associated with the common subscriber identification information of the group of subscriber terminals in the table and notifies the unused IP address to the sever, and the sever makes a call to a subscriber terminal in accordance with the unused IP address.

Abstract: Fault tolerant VoIP systems and methods to operate the same are disclosed. An example method comprises receiving a registration request at an edge device of a voice over Internet protocol (VoIP) system from a user device, selecting at the edge device a communication service providing device from a list of devices configured to provide communication services, sending the registration request to the selected communication service providing device, and receiving a registration response from the selected communication service providing device.

Abstract: Handling an incoming call from a caller to a user includes prompting a caller to record a message to the user and sending a special command to a user communication device indicting that the incoming call is available for screening and retrieving. In response to the user indicating a desire to screen the incoming call, the user listens to the message while the caller is leaving the message. In response to the user indicating a desire to retrieve the incoming call, the call is transferred to the user communication device. In response to the user indicating a desire to screen the call, an incoming media stream from the incoming call may be forked so that the message is being recorded while the user is listening to the message at the user communication device.

Abstract: Methods for multi-user detection in a CDMA-based channel for use in a base station receiver are provided. Signals, each including a CDMA code, are received. Correlation operations are performed on CDMA codes of received signals respectively to obtain corresponding first correlation values. CDMA codes are divided into first and second code groups according to a threshold and corresponding first correlation values. An interference cancellation procedure is performed on received signals to remove signals corresponding to first code group therefrom and to obtain a removed signal. Correlation operations are performed on CDMA codes of removed signal to obtain corresponding second correlation values. Each first correlation value is subtracted from a corresponding second correlation value and compared with a threshold to generate a comparison result.

Abstract: Methods and apparatuses to initiate callback with confirmation. In one embodiment, a method includes: receiving a reference (e.g., a callback phone number) in a request for a connection to a destination; providing a code via the reference in response to the request; receiving a code to confirm the request; determining whether the received code matches the provided code; and initiating a connection via the reference for the connection to the destination if the received code matches the provided code.

Abstract: A system and method for routing and interacting with a dual mode network telephony environment are disclosed. In one embodiment, the system includes an external analog telephony line, a DSL modem, an analog telephony bridge controller, one or more additional analog telephony lines, and a communication center computer. The system routes analog and Voice-over-Internet Protocol calls between the analog telephony lines and the communication center computer. Furthermore, the communication center computer performs operations on calls inbound to the environment and calls outbound from the environment.

Abstract: In a network in which to set up a call to a called endpoint a calling endpoint sends (4) the called endpoint a call set-up message including a source information element identifying the calling endpoint and a destination information element identifying the called endpoint, the call is set up on condition that the call set-up message contains a first token value (J) that corresponds to a second token value given by an equation that includes said source information element, said destination information element, and a random information element generated by the network to be associated secretly with the first token value in the network.

Abstract: In a method for processing contents of a Session Initiation Protocol (SIP) message, a SIP sender sends a SIP message, and a SIP network content processing entity sets the message contents of the SIP message based on an acquired management strategy for the message content. A network for processing contents of a SIP message is also provided. Message contents of the SIP message may thereby be changed in the SIP message in accordance with the user's will and the strategy of the operator.

Abstract: Disclosed is a data call terminating service system and method for a dynamic IP of a mobile communication terminal.

Abstract: A method of receiving at a terminal a first signal transmitted via a communication network, said method comprising the steps of; receiving at the terminal the first signal comprising a plurality of data elements; analysing characteristics of the first signal; receiving from a user of the terminal a second signal to be transmitted from the terminal; analysing characteristics of the second signal to detect audio activity in the second signal; and applying a delay between receiving at the terminal and outputting from the terminal at least one of said plurality of data elements; and adjusting the delay based on the analysed characteristics of the first signal and on the detection of audio activity in the second signal.

Abstract: A telephone connection is established between a first terminal and a second terminal. The first terminal is presumed to be associated with a subscription in a first home telephone network in which the terminal is identified by a first network identity. Correspondingly, the second terminal is presumed to be associated with a subscription in a second home telephone network in which the second terminal is identified by a second network identity. A host resource routes a call from the first terminal to the second terminal based on a combination of the first network identity and a first common telephone number in the first home telephone network dialed by the first terminal. The first common telephone number is selected such that it is unique and is adapted to be shared among a group of users in the first home telephone network.

Abstract: The present invention relates generally to telecommunications and in particular to systems and methods for routing telephone calls. A first address, such as a first phone number, can be associated with a telephonic terminal, such as a fixed or mobile phone. Incoming calls to the first address can be routed using an Internet Protocol, such as SIP, or other protocol to the telephonic terminal or to other destinations based on telephonic terminal status and/or based on a user instruction.

The first registration-coupled subscription is transmitted, and a response is received to the first registration-coupled subscription, wherein the response confirms the subscription to the event package.

Abstract: A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.
