Abstract: A method to discriminate a signal as a DTMF digit is operative in a service provider having a VoIP-based media server. The media server accepts both in-band DTMF and RTP telephone events. A digit detection module receives as input a data stream that may include one or more DTMF digits. The module processes the input data stream and provides, as output, an indication of what digit(s) have been detected and from what source (e.g., in-band audio, an RTP 2833 telephone event, of both). The output is then further processed by a discrimination algorithm to make a final digit determination. If RTP telephone events are detected, the algorithm prefers them and ignores in-band DTMF until the call ends or the media is re-negotiated. The approach detects when duplicate digits of differing types are initially received and only accepts one of them, regardless of spacing or duration.

Abstract translation: 将信号识别为DTMF数字的方法在具有基于VoIP的媒体服务器的服务提供商中可操作。 媒体服务器接受带内DTMF和RTP电话事件。 数字检测模块作为输入接收可以包括一个或多个DTMF​​数字的数据流。 该模块处理输入数据流并提供已经检测到哪些数字的指示，以及从什么源（例如，带内音频，两者的RTP 2833电话事件）提供输入数据流。 然后通过鉴别算法进一步处理输出以进行最终数字确定。 如果检测到RTP电话事件，则算法更喜欢它们，并忽略带内DTMF，直到通话结束或媒体被重新协商为止。 该方法检测到不同类型的重复数字最初被接收并且只接受其中一个，而不考虑间隔或持续时间。
