Abstract:
1. A method comprising: generating, by a testing subsystem, a digit map in response to user input received by way of a graphical user interface, the digit map defining a digit sequence and a plurality of dual-tone multi-frequency (“DTMF”) properties associated with each digit included in the digit sequence; generating, by the testing subsystem, DTMF tones representing the digit sequence in accordance with the DTMF properties; transmitting, by the testing subsystem, the DTMF tones to a gateway device communicatively coupled to the testing subsystem, the gateway device configured to translate the DTMF tones into a packet-based representation of the digit sequence and the DTMF properties; receiving, by the testing subsystem, the packet-based representation of the digit sequence and the DTMF properties from the gateway device; and testing, by the testing subsystem, the gateway device to determine whether the gateway device accurately translates the DTMF tones to the packet-based representation by determining whether the digit sequence and the DTMF properties included in the packet-based representation substantially match the digit sequence and the DTMF properties defined by the digit map.
