Dialing prefixes
Apart from the numbers above, the terminal uses the following dialing
prefixes:
• 1* before the phone number will force the connection to use Standard
Voice.
• 2* before the phone number will force the connection to use 3.1 kHz
Audio.
• #31# before the phone number will hide the callers phone number to the
recipient.
• *31# before the phone number will show the callers phone number to the
recipient where it would otherwise be hidden, e.g. because the number is
an ex-directory number.
• R is used during a call to indicate that the following key-presses should
activate a supplementary services function. The supplementary services
functions supported by the terminal are described in the subsequent
sections.
Making local phone calls
You can make local calls between various phones connected to the terminal.
Local phone numbers always start with 0.
For an overview of the numbers, see Special-purpose numbers on page 45.
To make a local call, dial
<local number> followed by # or off-hook key.
Local numbers of analog phones, ISDN phones and IP handsets are assigned
according to the table in Special-purpose numbers on page 45. Note that if
you are using local numbers for ISDN devices, the numbers must be
programmed in the devices. For further information refer to the
documentation for your ISDN device.
