5.2 Call
waiting
If you urgently wish to contact a busy extension, you can indicate to that
extension that there is a Call waiting. The Call waiting is indicated either
by a tone (the busy extension is an analogue extension) or as a second
call (the busy extension is a digital system telephone or an H.323 IP tele-
phone). If the called extension is not allowed to receive Call waiting
signals, you will continue to hear a busy tone. If the busy extension
ignores the Call waiting tone, you can initiate Call back.
The capability of initiating or receiving a Call waiting indication is
controlled by a category (programmed by the system administrator).
