ToneScript is a mini script used to describe the characteristics of Call progress tones

Description[edit]

A call progress tone is a pattern of tones made audible to the caller, conveying some status about the call. Despite its name, a call-progress tone could be a sequence of tones, that may be repeated or emitted just once. ToneScript is a mini script that describes the pattern of frequency, cadence and level of tones in call progress tones. Many internet telephony devices using more sophisticated operating systems permit users to customize the tones. Customarily the devices are preset with the standard tones defined and regulated by standards bodies in a given region. ToneScript is used in Sipura, Linksys and Cisco family of IP telephony products.

Format[edit]

  • ToneScript may have at most 120 characters.
  • A calling tone may use up to 6 frequency components n_k where 1 < k < 6
  • A cadence section Z_i indactes its Duration D_i followed by up to 6 subsections ZZ_{i,j} in parenthesis. A subsection consists of an ON duration (* for always on), an OFF duration and the list of frequency components f_{i,j} used in that subsection.
f_{i,j} := n_1[+n_2[+n_3[+n_4[+n_5[+n_6]]]]]
ZZ_{i,j} := on_{i,j}/off_{i,j}/f_{i,j}
Z_i := D_i([ZZ_{i,1} [,ZZ_{i,2} [,ZZ_{i,3} [,ZZ_{i,4} [,ZZ_{i,5} [,ZZ_{i,6}]]]]])
  • A FreqScript is a sequence of frequencies F_i in hertz and their corresponding levels L_i in dBm
    FreqScript:=F_1@L_1[,F_2@L_2]
  • A Tone Script has a frequency specification and one or two cadence sections.
ToneScript:=FreqScript;Z_1[;Z_2]

Examples[edit]

  1. 350@-19,440@-19;10(*/0/1+2)
    Contains 2 frequencies components
    Frequency component 1 is 350 Hz at -19 dBm
    Frequency component 2 is 440 Hz at -19 dBm
    There is 1 Cadence Section
    In this section, The duration is 10 seconds and the tone has only 1 subsections
    In the only subsection the tone is always on, off for 0 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)
  2. 350@-19,440@-19;2(.2/.2/1+2);10(*/0/1+2)
    Contains 2 frequencies components
    Frequency component 1 is 350 Hz at -19 dBm
    Frequency component 2 is 440 Hz at -19 dBm
    There are two Cadence Sections
    In the first Cadence Section, The duration is 2 seconds and the tone has only 1 subsections
    In the only subsection the tone is on for 0.2 seconds, off for 0.2 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)
    In the second Cadence Section, The duration is 10 seconds and again the tone has only 1 subsections
    In the only subsection the tone is always on, off for 0 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)
