  • Patent number: 9735981
    Abstract: Session initiation protocol (SIP) trunking can be facilitated via a mobility network comprising a router and a virtual internet gateway. A router associated with a private branch exchange, can comprise a cellular modem to facilitate radio communication with a cellular network. The router can also perform operations associated with converting wireline signal data to cellular signal data and cellular signal data to wireline signal. A mobility network can also convert wireline signal data to cellular signal data via a virtual Internet gateway that can be used to encrypt or decrypt a voice signal.

  • Patent number: 8072970
    Abstract: A method is provided for forming a multi-media communication path between at least first, second and third communication devices coupled to a multi-media provider system during post answer call redirecting and/or teleconferencing. The method includes receiving and processing a first call request at a circuit-based portion of the multi-media provider system for forming a first communication link between the first and second communication devices. Thereafter, predetermined attributes of the first communication link may be sent to an IP-based portion of the multi-media provider system for configuring the IP-based portion of the multi-media provider system to process a subsequent request to execute post answer call redirecting and/or teleconferencing.

  • Patent number: 6771762
    Abstract: An AIN system having a service switching point (SSP), a service control point (SCP) and an intelligent peripheral (IPe) is disclosed. A calling party makes a call to a called party which results in a trigger signal at the originating SSP. The trigger signal causes the SSP to access the SCP which, in turn, sends a Send_to_Resource message to the SSP. In response to the Send_to_Resource message, the SSP establishes a first connection to an IPe, whose functionality is required. The IPe establishes a second connection carrying a second call to the called party, the first and second calls being connected at the IPe. The IPe subsequently requests that the SSP merge the first and second calls. In response, the call between the called party and the calling party is connected via the SSP, thereby releasing the IPe connections formerly used to connect calling and called parties.

  • Patent number: 6594257
    Abstract: A network-based method for initiating and completing a voice telephony call via the Internet comprises the steps of receiving call completion data at a voice/data network gateway of the public switched telephone network from an Internet application web server, which may comprise an Internet service provider or other entity serving Internet users via an Internet application web server, and transmitting call completion data to telecommunications switches for connecting an Internet user to a telephone of an application agent associated with the Internet server. The application agent may be associated with a 1-8YY toll-free number or other national or international telephone number. Call progress data is translated into data communications protocol format to be returned to the Internet server where it may be displayed to the user. Preferably, the link between the Internet application web server and the voice/data network gateway comprises a telecommunications data link, for example, an ISDN data link.

  • Publication number: 20030108179
    Abstract: An enhanced intelligent network telephony system includes at least one service nodes (SN) imbued with special routing, message handling and billing capabilities. Using the Extension Parameter in an Analyze-Route message, a service control point (SCP) provides a set of service node parameters including service node identification and message content. The SN receives, processes and implements the services corresponding to the message content. Included among these may be announcement IDs corresponding to announcements, such as advertisements, that the SN can initiate at an intelligent peripheral for playing to calling and called parties, and routing numbers which the SN can use to route a particular destination under certain conditions as per the service needs. The SN is also able to request an originating switch to update an Automated Message Accounting (AMA) record created at the originating switch, using information created by the SN.
