to the extension when receiving trunk calls, doorphone calls, external sensor calls and hold-recall calls.
Through system programming, it is also possible to select whether extensions will receive Automatic
Call Waiting from intercom calls.

• Call Waiting Tone
A PT user can hear different Call Waiting tones for trunk call and intercom call if "Tone 2" has been
selected through personal programming (Call Waiting Tone Type Selection). If "Tone 1" has been
selected, the same Call Waiting tone will be heard for both trunk call and intercom call.
All Call Waiting tone patterns have a default (→ 3.2.1 Tones/Ring Tones).
• Caller Information
With the Call Waiting tone, the caller's information flashes on the display for five seconds, followed by
a 10-second pause, then flashes again for five seconds.
• Call Waiting from the Telephone Company
Besides the Call Waiting service within the PBX, the Call Waiting tone offered by an analogue line from
the telephone company informs the extension user of another incoming trunk call that is waiting. He can
answer the second call by disconnecting the current call or placing it on hold using EFA. For details,
consult your telephone company.
