1 Introduction

The Real-Time Transport Protocol (RTP/RTCP): DTMF Digits, Telephony Tones, and Telephony Signals Data Extensions Protocol (RTPDT) is an extension to [RFC4733]. RTPDT describes the payload format needed to carry DTMF digits, tones, and signals in RTP packets over a network transport.

Any behavior not explicitly defined in this document means the behavior defined in [RFC4733] must be used.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
