Call Waiting Tones
Call Waiting is a feature that tells you if a new caller is trying to contact you when
you are already on the phone.
A discreet tone alerts you to the new caller, so you can answer your second
incoming call by putting your first caller on hold.
The IP phones use the following Bellcore-specified call waiting tones.
Bellcore
Call-Waiting Tone
CallWaitingTone 1
Bellcore-dr2
CallWaitingTone2
Bellcore-dr3
CallWaitingTone3
Bellcore-dr4
CallWaitingTone4
For Asterisk and Broadworks servers, call waiting tones are specified by the
default Bellcore tones indicated in the table
Broadworks Servers)
For Sylantro servers, call waiting tones are specified by the Bellcore tones you
configure in the Aastra Web UI or the configuration files. See the table
Pattern (Sylantro Servers)
5-78
Note: If the "Do Not Disturb" (DND) or the "Call Forward" (CFWD)
feature is enabled on the server-side, and the user is still waiting for a call,
the "Bellcore-dr5" is a ring splash tone that reminds the user that these are
enabled.
