Administrator's Guide for SIP-T2 /T3 /T4 /T5 /CP920 IP Phones
For other phones:
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. (for
example, 250/200,0/1000,200+300/500,200+500+800+1500/1000).
If you want the IP phone to play tones once, add an exclamation mark "!" before tones (for example,
!250/200,0/1000, 200+300/500,200+500+800+1500/1000).
Note: It works only if "voice.tone.country" is set to Custom.
