Calling emergency numbers
Numbers specified as emergency numbers can be dialled even when the keyboard is locked! See
"emergency nos" on how to set emergency numbers. Several numbers (911, 112, 110, 999) have
been preconfigured.
• On an unlocked keyboard: Enter the number and press
to dial.
• On a locked keyboard: Enter the number. The phone dials the number as soon as you have
entered all the digits.
Call completion
Note: This function depends on whether it is available in your network or not. On snom
phones call completion means that when a called number is busy or not available, your
phone will call you back as soon as the dialed number is not busy anymore or available
again. The factory default setting is "off".
Changing the setting to turn on call completion : See "Call completion" on page 71.
When call completion is enabled,

will appear in the function key line whenever you dial a
number. Press
CC
to activate call completion for this call.
• Press
Cancel

• Press
Ok
if you wish to dial another number while waiting for call completion. You can

completion will not interfere with the normal operation of your phone.
When the number becomes available, you will see it announced on the display and hear a single long
beep.
