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.

			Minimum	Nominal	Maximum
Bellcore	Pattern		Duration	Duration	Duration
Call-Waiting Tone	ID	Pattern	(ms)	(ms)	(ms)
CallWaitingTone 1	1	Tone On	270	300	330
Bellcore-dr2	2	Tone On	90	100	110
