Dialing

Speed dialing is initiated by typing in a number from 0-30, *, or #,
respectively, and confirming with the key. In this way, 33 speed
dial numbers can be called up without having to look at the display.

Editing speed dial entries

Set up the speed dial numbers on the built-in web interface page of
your phone.
Deny List
The snom 220 gives you the option of putting numbers on a deny list to
prevent calls from these numbers.

Browsing

You get to the deny list window via the submenu “Deny List” on your
phone’s display.
