Methods, systems, and devices for providing voice-call services responsive to a dialed sequence
First Claim
1. A method of establishing a connection in a communications network, the method comprising:
- receiving a Dual Tone Multi-Frequency (DTMF) signal at a port having an assigned sequence associated therewith;
identifying a dialed sequence corresponding to the received DTMF signal;
populating first and second fields of a packet-switched signaling protocol message with the assigned sequence associated with the port if the dialed sequence is associated with a request for a specified service;
transmitting the populated packet-switched signaling protocol message over a packet-switched network to request the specified service; and
establishing a connection to provide the specified service through the port.

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.

11. A network access device, comprising:
-
a port having an assigned sequence associated therewith and configured to receive a Dual Tone Multi-Frequency (DTMF) signal;
a controller configured to identify a dialed sequence corresponding to the received DTMF signal and populate first and second fields of a packet-switched signaling protocol message with the assigned sequence associated with the port if the dialed sequence is associated with a request for a specified service; and
a transmitter configured to transmit the populated packet-switched signaling protocol message over a packet-switched network to request the specified service. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of establishing a connection between a Public-Switched Telephone Network (PSTN) and an Internet Protocol (IP) network, the method comprising:
-
identifying a dialed sequence corresponding to a Dual Tone Multi-Frequency (DTMF) signal received at a port of a PSTN/IP gateway device, the port having a first sequence associated therewith;
associating a second sequence that is different from the dialed sequence with the identified dialed sequence at the PSTN/IP gateway device if the dialed sequence is associated with a specified service; and
transmitting a packet-switched signaling protocol message including the first sequence and the second sequence from the PSTN/IP gateway device to a server over a packet-switched network to request the specified service.
