Customizes the Ring Tone 1 to 3 with associate caller ID: when selected, if
caller ID is configured, then the device will ONLY use this ring tone when the
incoming call is from the Caller ID. System Ring Tone is used for all other
calls. When selected but no Caller ID is configured, the selected ring tone will
be used for all incoming calls using the FXS port. 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: ;info=ring5
