7.3 The Flash Key
Flashing means to press the hook for a short period of time (a few hundred milliseconds) before
releasing it. On newer telephones, there should be a “flash” key (button) that generates the signal
electronically. If the flash key is not available, you can tap (press and immediately release) the
hook by hand to achieve the same effect. However, using the flash key is preferred since the
timing is much more precise. With manually tapping, if the duration is too long, it may be
interpreted as hanging up by the Prestige.
7.4 Call Waiting
ISDN Call Waiting allows you to place a call on hold while you answer another incoming call on
the same telephone (directory) number.
By default call waiting is enabled on both telephone ports (except France where the default is
disabled), but can be toggled on either port from Menu 2.1.
7.4.1 How to use call waiting
The Call Waiting feature on your ISDN line works in exactly the same way as it does on a regular
analog line (which almost everyone is familiar with). To put the current call on hold and answer
the incoming call, press the flash key after hearing a call waiting indicator tone.
Dropping current call to switch to incoming/holding call.
After hearing a Call Waiting indicator tone, simply hang up the telephone and wait for the
telephone to ring before answering the incoming/holding call.
Notes: An incoming caller receives a busy signal if
♦ You have two calls active (one active and one on hold, or both active using Three Way
Calling) already.
♦ You are dialing a number on the B-Channel the incoming caller is attempting to reach, but
have not yet established a connection.
7.5 Three Way Calling
Three Way Calling allows you to add a third party to an existing call. This service must be
subscribed from your telephone company.
