TONES AND RINGS
telling you what is going on. The various tones and
rings are described below.
Busy lone
Regular long pulses (beeep-beeep-beeep) - heard
when the number you dialed is busy.
Callback Ring
One short ring followed by three regular rings,
heard when the callback you set rings your phone.
Camp-on Tone
One (internal call waiting) or two (external call
waiting) short beeps, heard during a conversation
when you have an incoming call waiting to be
answered.
Conference Tone
One short beep, that may be heard, depending on
the way the system is programmed, before a new
party on a public network line joins a Conference
Call. If it is heard, the beep is repeated every 15
seconds for the entire duration of the call.
Expensive Warning Tone
Four short beeps, before the call is completed. If
your system has Automatic Route Selection (ARS),
you will hear this tone when no inexpensive routes
are available for your long-distance call. The tone
is a warning that your call is going to take the
most expensive route.
Interrupted Dial Tone
Several rapid pulses followed by dial tone, heard
when you lift the handset to indicate Call
Forwarding has been activated.
Message Waiting Ringing
Three rapid rings (ring-ring-ring) heard when you
have a message waiting.
