IDNA (RFC 3490) Support: Switch on support for Internationalizing
Domain Names in Applications (IDNA). IDNA support is the ability to
handle domain names including international special characters.
Action on Ethernet cable replug: Choose the action to be
performed after the network connection is reestablished: „Do nothing“
or „reboot“.
Auto Dial: This setting is switched off by default. You can set a
timeout after which a number is dialed automatically without pressing
or taking the handset off the hook.
Number Guessing: Here, the number guessing functionality can
be activated or deactivated. This is the automatic number completion
which begins after you have entered the second digit of the number you
are dialing.
Block URL Dialing: You can block the dialing of SIP URLs by
turning this setting on. In this case only numeric numbers will be allowed
as input.
Deny All: When this feature is set to “on”, the “Deny Call” function
key will be available on the display when calls are coming in, so that any
undesirable incoming numbers may be put on the “Deny List”.

snom phones can handle challenge responses on the phone. Turning this
setting off will disable this feature and you will only be able to handle
authentication through the web interface of the phone.
Enable Intercom: Here, you can explicitly select whether or not
you want to participate in the intercom functionality. If you enable it, the
intercom functionality can be programmed onto the function keys set to
type “Intercom” (see “Confi guration Line 1-12).

at the registrar without authentication, intercom also works without
authentication.
CMC (Client Matter Code): When this setting is turned on, the
user is offered the function key “CMC” during a call; its use sends a code
to the server using the INFO message in SIP. This code can later be used
for billing or bookkeeping along with the call ID of that call.
Dialog-Info Call Pickup: snom phones subscribe to the status
information of SIP URLs mapped as “Destination” on the programmable
