Instruction manual

Call Waiting

Description

This feature allows a user at a busy voice terminal to be audibly alerted when another party

is calling. A voice terminal is considered busy if all its System Access (SA) buttons are in use

(multiline sets), if it is off-hook (single-line sets), and if all coverage points are busy.

With Call Waiting, the user hears a distinctive call waiting tone from the handset one time;

the caller hears special ringback tone, repeated. Calls from both inside stations and outside

locations (on non-DID trunks) receive call waiting treatment at stations administered for this

feature.

The called party who hears call waiting tone has these options:

● Ignore the new call and continue with the current call.

● Terminate the current call, hang up, and answer the new call when it rings.

● Put the current call on hold and answer the new call.

A user at a busy single-line terminal flashes the switchhook to hold the current call. Dialing

✶ 9 then connects the user to the new call.

At a multiline voice terminal with all SA buttons busy, the user can answer a waiting call on

an idle SA-Originate Only or Bridged Access (BA) button. After putting the current call on

hold (with the HOLD button), the user presses the SA-Originate Only or BA button and dials

✶ 9 to be connected.

Call waiting tone consists of one beep (high frequency tone) for an inside call or two beeps

for an outside call. Special ringback consists of normal ringback with a short separate tone

added at the end of each cycle. Special ringback continues until the called party answers.

Considerations

Call Waiting improves the chances of incoming calls to busy terminals being answered.

The caller must remain off-hook for a waiting call to be answered.

The Call Waiting feature also applies to calls extended to busy inside stations by attendants

(Camp-On). A busy extended-to party receives call waiting tone, and the caller receives

special ringback.

The call returns to the console after a predefined interval if it is not

answered.
