Abstract:
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, the port having an assigned numerical sequence associated therewith; identifying a dialed sequence corresponding to the received DTMF signal, wherein the dialed sequence is associated with a request for a specified service; in response to identifying the dialed sequence as associated with the request for the specified service, populating a first field of a packet-switched signaling protocol message with the assigned numerical sequence and populating a different second field of the packet-switched signaling protocol message with the assigned numerical sequence, wherein each of the first and second fields of the packet-switched signaling protocol message are populated with the same assigned numerical sequence associated with the port at which the DTMF signal is received; 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.
