Dialing an IP Address
When you are calling an IP address, the called phone or computer cannot determine which user you want to reach. In SIP mode it is assumed that “anonymous” is being called and with H.323 no assumptions are made. This is the case with many phones and applications. Therefore, you should only use this method in exceptional cases, as the entry of IP addresses is rather cumbersome.
Number guessing
For your convenience this functionality offers you the first number from dialed numbers, missed calls, received calls, or numbers in the phonebook that match the beginning of the number you have already typed in.
If the displayed number is not the one you wanted, you can either keep pressing the “#” key (in alphanumeric modes) to get the next matching number or continue typing your desired number, or press the 
function key to temporarily switch off the number guessing for this session of editing a phone number.
Terminating a call
You can end a call by setting the handset on its cradle, pressing the hook switch, or pressing CANCEL 
. The snom 220 will terminate the call and return to the idle state.
