Distinctive Ring Tone
Custom Ring Tone 1 to 3 with associate Caller ID: when selected, if Caller ID is
configured, then the device will ONLY uses this ring tone when the incoming call is

Caller ID is configured, the selected ring tone will be used for all incoming calls using
the FXS port or Profile. Distinctive ring tones can be configured not only for matching a
whole number, but also for matching prefixes. In this case symbol * (star) will be used.
For example:
if configured as *617, Ring Tone 1 will be used in case of call arrived from the area
code 617. Any other incoming call will ring using cadence defined in parameter System
Ring Cadence located under Advanced Settings Configuration page.
Note: If server supports Alert-Info header and standard ring tone set (Bellcore) or
distinctive ring tone 1-10 is specified, then the ring tone in the Alert-Info header from
server will be used. Bellcore rings and tones are independent from custom ring tones.
The custom ring tones can also be specified by alert-info header, for example
Alert-Info: <http://127.0.0.1>;info=ring5
