Distinctive Ring
Tone
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
Disable Call
Waiting
Disables receiving a second incoming call when the line is engaged.
