Cadence for the tones as mentioned below:

• Error Tone
• Busy Tone
• Confirmation Tone

• Routing Tone
• Intrusion Tone
• Remote Hold Tone
• Remote Hold and Call Waiting Tone
How it works?
• Remote Hold Tone’ and ‘Remote Hold+Call Waiting Tone’ are
fixed
for all countries and are not programmable.
• You can select from two options of Call Progress tones for
remaining tones, Countrywise or Customized.
• If
Countrywise
option is selected, all Call Progress tone will be
played as per the country selected.
Customized Option:
• The gateway supports programmable Frequency and Cadence for
each tone. This is required if you want to set your own ‘type’ or if
the country is not supported by default.
• Each call progress tone will have following parameters associated
with it:
• Frequency Set (Frequency 1 and Frequency 2) to be used
