1. Requirements and Information
Using this snom IP telephone with your nfon telephone system merely requires a sound
broadband connection.
The snom 3xx series standard receivers do not support G.722 Codec. Thus, it is not
possible to provide HD voice quality as a standard. To achieve HD voice quality when
phoning within the company, you can order the klarVOICE receiver by snom. Please
contact your company’s sales representative for this purpose.
2. Adding an extension
All telephones you receive are preconfigured and connected to the telephone system.
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.
Permanent call forwarding (always)

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.
