Call Waiting

System Availability: All systems

When a station is busy with a call and another call is directed to that station’s busy Line or [DN] button, two short beeps are issued to alert the telephone user of the pending call.

Call Waiting works for calls originating from within or outside the system. The length of the Call Waiting beeps is different for internal and external Call Waiting. The different beeps distinguish which type of call is waiting.

Caller ID, DNIS or ANI information appears on LCD telephones for 10 seconds. If Caller ID information is not available, the device name, such as the CO line or DNIS name or number is shown.

Digital telephones can be adjusted to receive or not receive Call Waiting tone over the handset or headset receiver, as well as the speaker. Standard telephones will receive Call Waiting tone twice from the handset receiver. Call Waiting tones can also be turned off on each station by a System Administrator.

When a station is busy with a call and another call is being received, a tone alerts the caller of a pending call. On LCD telephones, the Caller ID information displays for 10 seconds. The combined effect of the Call Waiting alert tone with the displayed information enables users to

identify whether or not they want to interrupt their current call for the waiting call.

To answer the Call Waiting, the current call must be parked, terminated or transferred. Multiple calls can be queued to a single station, all waiting for that station to become free; the call at the head of the queue provides the Call Waiting signal and LCD indication.

This feature works with both digital and analog single-line telephones. The tone (two beeps) signaling Call Waiting tone is provided through the speaker of the digital phone. For standard analog telephones, the tone is inserted into the speech path. Caller ID display is not available with standard telephones.

Note Type II call waiting with Caller ID is not available with the R4.1 release of the BSTCIU or BCOCIU/BCOCIS interface cards.
