Using this snom IP telephone with your nfon telephone system merely requires a sound
broadband connection.

Find further information on how to install an extension in the administration portal
manual.

C. Notices
1. Encryption
You have the option of voice encrypting (SRTP) your telephone calls. You can activate this function
for your customer account via the administration portal at any time.
Activation of this function is subject to fees.
You can activate the function Voice Traffic encryption (SRTP) on the administration
portal under ADMINISTRATION / Profile.
- Activate the function on the administration portal.
- Restart all telephones. Restarting may take a few minutes. During a conversation a lock icon on
the telephone display indicates encryption is activated.
⇒ The active call is now encrypted.
2. Call forwarding
You can configure various call forwarding scenarios. For this purpose you can use the call
forwarding profiles.
Under the telephone menu you can only edit the default profle (catch all / always) to be found under
the call forwarding profiles. You can edit the remaining call forwarding profiles via Ncontrol or via
the administration portal. For more information, refer to the administration portal manual and the
Ncontrol manual.
The following call forwarding options are available. You can activate or deactivate call forwardings
via the telephone menu's call settings.

4
Permanent call forwarding (always)
All incoming calls will be forwarded directly to the predefined telephone number.
Forward if busy (busy)
New calls will be forwarded immediately, when coming in during an active call. This call forwarding
option functions only, if the Call Waiting function is deactivated.
Delayed call forwarding (no answer)
Call forwarding condition: You do not answer the incoming call within a defined time period
(timeout). The timeout can be set to 5, 10, 15 or 20 seconds. Where should the incoming call be
forwarded after the specified time has elapsed? The caller receives a call waiting signal and is then
forwarded to the defined destination.
If unavailable (not registered)
The option functions only if the end device is not registered to the telephone system:
When the Internet connection fails or there is no LAN connection.
and
If “call forwarding …if unavailable” is programmed for a direct extension (e.g. extension 123 -
John Doe) and a caller calls the direct dial number for the extension directly, call forwarding
applies. If the extension is a member of a queue or a group and the queue or group receives a
call, call forwarding for the individual extension no longer applies! In general, the destination
should always be an available destination number. I.e., make sure that no voicemail or
announcement comes on.
The display on your telephone indicates whether or not call forwarding is active.
Call forwardings can alternatively be activated through * codes:
*10 Activation of the call forwarding profile
*11 + destination Permanent call forwarding to telephone number
**11 Cancel permanent call forwarding
*12 + destination If no answer after a specific time, delayed call forward
to telephone number
**12 Cancel delayed call forwarding
*13 + destination If busy, forward to telephone number

5
**13 Cancel call forwarding if busy
*14 + destination Call forwarding if unavailable
**14 Cancel call forwarding if unavailable
3. “Hot desking”
The basic function of “Hot desking” allows cancelling the registration of existing users and
registering new users to your end device. This is useful when employees frequently change their
work station without taking along their end devices. After completing the registration process your
configuration is automatically transferred to the new telephone.
Cancelling the registration of the current extension
- Proceed as follows when in menu:
Menu -> Telephone settings -> Cancelling an extension -> Confirm
⇒ The extension is now cancelled and the telephone is restarted. This may take some time.
Registering the new extension
- Proceed as follows when in menu:
Menu -> Enter the extension number -> Confirm -> Enter voice mail PIN -> Confirm
⇒ The new extension is now registered. This may take some time.
