voice.tone.dial
Description:
Customizes the dial tone.
tonelist = element[,element] [,element]...
Where
element = [!]Freq1[+Freq2][+Freq3][+Freq4] /Duration
Freq: the frequency of the tone (ranges from 200 to 4000Hz). If it is set to 0Hz, it means the
tone is not played.
For T40P:
A tone is comprised of at most two different frequencies.
For T48G/T46G/T42G/T41P:
A tone is comprised of at most four different frequencies.
Duration: the duration (in milliseconds) of the dial tone, ranges from 0 to 30000ms.
You can configure at most eight different tones for one condition, and separate them by
commas. (e.g., 250/200,0/1000,200+300/500,200+500+800+1500/1000).
If you want the Skype for Business phone to play tones once, add an exclamation mark "!"
before tones (e.g., !250/200,0/1000,200+300/500,200+500+800+1500/1000).
Note: It works only if the value of the parameter "voice.tone.country" is set to Custom.
