Distinctive Ring
Tone
Select a Distinctive Ring Tone 1 through 3 for the caller ID. The Caller ID can be
configured as a particular caller ID or Alert-Info text.
When a particular call ID is configured in the Caller ID, the selected ring tone will be
used when the incoming call is from the Caller ID. System Ring Tone will be used for
all other calls.
If server supports Alert-Info, the Alert-Info text can be mapped to the 3 customized
ring tones. For example, if you configure the custom ring tone 1 user ID to “priority”,
that ring tone will be used if we receive INVITE with Alert-Info header in the following
format:
Alert-Info:;info=priority

- Cadence on and off are in 10ms
- ON is the period of ringing (“On time” in “ms”) while OFF is the period of silence
- In order to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms
and a pause of OFF ms and then repeat the pattern
