  • Patent number: 7496190
    Abstract: A method and system for providing call forwarding in an IP telephone network is disclosed. First, when a telephone number for a first telephone from a second telephone is dialed, the call is routing to a call manager. Call setup procedures with a BRG responsible for the first telephone are then initiated. The BRG then checks stored call forwarding profiles to determine whether there is an active call forwarding profile for the first telephone. The call is connected to the first telephone if an active call forwarding profile is not found. However, if an active call forwarding profile is found, the call forwarding information is sent to the call manager. The call is routed to at least a third telephone based on the call forwarding information.

  • Publication number: 20080285726
    Abstract: Surveillance of IP telephony may be performed through the use of conventional telephone equipment, according to principles of the invention while preventing giving indication to the monitored phone by alerting the user of the monitoring phone to such surveillance use prior to pick up by an agent for engagement of the monitoring phone in response to the alert. Such alerts may assume many forms such as ringing, visual indicators, data readouts, activating ancillary equipment, various flags, etc. This alert prior to surveillance is distinct from alerts used for normal non-surveillance calls, which the monitoring phone is capable of receiving.

  • Patent number: 7289489
    Abstract: A method of billing a variable bit rate communication between a first terminal and a distant terminal to a broadband subscriber permits changing billing parameters during a call in real time in response to user inputs including user requested changes in quality of service, changes in data rate and changes in preferred service provider. A variable bit rate communication to be billed has a variable quality of service related to the degree of utilization of a plurality of different networks. The billing method comprises the steps of i.) receiving user identification data at a first terminal and data representing a required bit rate and a default quality of service selected by the user, ii.) verifying the user identification data to be associated with the broadband service subscriber, iii.) determining least cost alternative network resources available for achieving the communication at the user selected default quality of service and the required bit rate, iv.

  • Patent number: 7180889
    Abstract: A method and apparatus for providing multiple telephone lines using a single directory number. A method and apparatus for associating multiple directory numbers with multiple telephone lines. A broadband residential gateway (BRG) is a user interface to a broadband communication system providing packetized telephone service and other media services. The BRG has multiple ports, and each port is connected to one or more telephones. The multiple ports may be mapped to a single directory number, or the multiple ports may be mapped to multiple directory numbers. The BRG can provide greeting and message features. A greeting may instruct a caller to select a port which is associated with a party the caller is attempting to reach. Also, a message, played after the greeting, may further instruct the caller.

  • Patent number: 6917610
    Abstract: The present invention provides for an activity log which may include user proactive billing management for use in a broadband communications system that guarantees voice, data and video communication reliability and security to users for an integrated telephone, television and data network. The activity log and user proactive billing management may log incoming calls directory numbers (DNs) and outgoing call DNs in a database that may be provided at a central system location, such as the IP Central Station or at the system subscriber's customer premises equipment. The activity log may also log incoming and outgoing email interactive sessions (e.g., instant message (IM) email) and log multimedia video and audio calls. According to a variation of the invention, the user may access the activity log(s) and identify any communication the cost of which should be billed to a different party. The activity log may also be sorted based on user preferences and set to direct calls to low cost alternatives.

  • Publication number: 20040228336
    Abstract: In an internet telephony system, toll-free service and the calls that are accepted and paid for can be specified by the IP telephony system user to be limited according to the calling party's identity, time of day, day of week or other criteria Data that is used to screen or filter incoming calls is programmed into a call manager by the IP telephone system user's broadband residential gateway. Using such a system the user can carefully screen calls that are paid for and more closely control telecommunications service costs. More generally, the user has the ability to store predefined call handling criteria, which may be executed by the broadband residential gateway and/or the call manager.

  • Patent number: 6687360
    Abstract: A method and system for providing a dynamic call forwarding service for a subscriber in an IP telephone network is disclosed. When a predetermined telephone number is called from a telephone other than the subscriber's home telephone, the subscriber enters a code for location registration. The directory number of the telephone the subscriber is using is determined for location registration. A call for the subscriber's home telephone is then routed to the telephone the subscriber used for location registration.

  • Patent number: 6678265
    Abstract: A method for connecting a call in an IP telephony system is disclosed. A dialed unique identifier is routed to a network device. The network device determines whether the dialed unique identifier has been ported. If the dialed unique identifier has not been ported, the network device attempts to connect the call to the dialed unique identifier. If the dialed unique identifier has been ported, new routing information is sent from a database to the network device. The network device then attempts to connect the call using the new routing information.

  • Patent number: 6671262
    Abstract: A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network. The system may include one or more conference servers for combining IP packet streams in a conference call into a combined IP packet stream, such that the combined IP packet stream utilizes no more bandwidth than each of the original IP packet streams. This allows the traffic volume coming from, and arriving at, each party to a conference call to remain essentially the same no matter how many parties are connected to the conference call. A plurality of the conference servers may be configured to interwork with each other so as to allow for a much larger conference call.
