ToneScript is a description syntax for the characteristics of call-progress tones.

A call progress tone is a pattern of audible tones played to the caller in a telephone call, conveying the status of the call. ToneScript describes the pattern of frequency, cadence, and level of the signal. Many Internet telephony devices support configuration options for users to customize the tones, but standard patterns are provided for various telephone administrations. ToneScript is used in Sipura, Linksys and Cisco family of IP telephony products.

Format[edit]

  • A ToneScript syntax may have at most 120 characters.
  • A calling tone may use up to 6 frequency components where
  • A cadence section indicates its Duration followed by up to 6 subsections in parenthesis. A subsection consists of an ON duration (* for always on), an OFF duration and the list of frequency components used in that subsection.
  • A FreqScript is a sequence of frequencies in hertz and their corresponding levels in dBm
    @@
  • A Tone Script has a frequency specification and one or two cadence sections.
