Logon

By choosing a different line, your originator phone number is changed to

this line. This means that different people can start calls from the same

phone with their own originator phone number and the called phone will

display this current outgoing line information. The current outgoing line

is marked on the idle screen with a black-colored phone icon in front of

the registered SIP line.

DND Mode on/off

Independent from Logon Wizard settings, the DND functionality is

available in the snom menu. DND is short for “Do Not Disturb”. If this

mode is activated incoming calls will no longer come through to the

phone and you will be completely undisturbed by the phone. If there is

a mailbox set up for you, the call is redirected to it. Before this mode is

activated, you will be asked if you really want to change to this mode.

In idle mode, “DND active!” is displayed in the bottom left-hand corner

of the screen when DND is activated.

Challenge/Authentication

In SIP, a user can also set up authentication requirements for each

registration on the phone. The password for each account name can be

set up via the web interface of the phone in Lin1-7 / Login Information /

Password.

If the authentication password is not set, or set wrongly, the account

will not register on that domain and the phone will be challenged for

that line. A challenge response will ask for the correct password. This

can look like:

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 66 67
