Methods, systems, and devices for providing voice-call services responsive to a dialed sequence
First Claim
1. A method of establishing a connection between a Public-Switched Telephone Network and an Internet Protocol network, the method comprising:
- receiving a Dual Tone Multi-Frequency signal corresponding to a dialed sequence at a port of a network access device, the port having a first numerical sequence associated therewith;
identifying the dialed sequence as a request for a specified service, wherein the specified service is different than a connection with a port associated with the dialed sequence;
populating an origination field of a session initiation protocol message with the first numerical sequence;
populating a destination field of the session initiation protocol message with a second numerical sequence that is different from the dialed sequence responsive to identifying the dialed sequence as the request for the specified service; and
transmitting the session initiation protocol message including the first numerical sequence and the second numerical sequence from the network access device to a server over a packet-switched network to request the specified service.

Abstract
A connection is established in a communications network responsive to receiving a Dual Tone Multi-Frequency (DTMF) signal at a port having an assigned sequence associated therewith. A dialed sequence corresponding to the received DTMF signal is identified. If the dialed sequence is associated with a request for a specified service, first and second fields of a packet-switched signaling protocol message are populated with the assigned sequence associated with the port. The populated packet-switched signaling protocol message is transmitted over a packet-switched network to request the specified service, and a connection is established to provide the specified service through the port. Related systems and devices are also discussed.

17. A computer program product for establishing a connection in a communications network, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein, the computer readable program code comprising:
-
computer readable program code executable to receive a Dual Tone Multi-Frequency signal corresponding to a dialed sequence at a port of a network access device, the port having a first numerical sequence associated therewith; computer readable program code executable to identify the dialed sequence as a request for a specified service, wherein the specified service is different than a connection with a port associated with the dialed sequence; computer readable program code executable to populate an origination field of a session initiation protocol message with the first numerical sequence; computer readable program code executable to populate a destination field of the session initiation protocol message with the second numerical sequence that is different from the dialed sequence responsive to identifying the dialed sequence as the request for the specified service; and computer readable program code executable to transmit the session initiation protocol message including the first numerical sequence and the second numerical sequence from the network access device to a server over a packet-switched network to request the specified service. - View Dependent Claims (18, 19, 20)
