Welcome!
This manual helps you to optimize the usage of the IP telephone in combination with the PBX. Please use this manual at initial operation. Some features differ from the features described in the manufacturer's documentation.
The following pages describe the snom 300, 320, 360 and 370 system telephones.
We wish you success and joy in working with your new telephone and this manual!

Version 1 / 10.2016 (en)
Die snom 3x0 Reihe is End of Life (EOL).

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.
All telephones you receive are preconfigured and connected to the telephone system.

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.
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)
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.
Active call forwarding will be shown on your telephone display.
Active call forwarding will be shown on your telephone display.
Call forwarding codes
Call forwardings can alternatively be activated through * codes:
| *10 | Activation of the call forwarding profile |

| **11 | Cancel permanent call forwarding |
| *12 + destination | If no answer after a specific time, delayed call forward to telephone number |

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.
