No content available.
Initial operation requires an NFON Deployment PIN . This is "40001998". A connection to the telephone system can only be established after entering this PIN. This PIN is only required once, during initial operation. When restarting the phone at a future time the PIN is already saved and does not need to be reentered.
- Using a Unify OpenStage SIP phone with the NFON telephone system requires a V3 R1.21. or V3 R1.38. firmware or later.
- When purchasing phones from NFON we can guarantee a compatible firmware is preloaded.
- Unify OpenStage phones are available in 3 versions. The standard sold by NFON is the "SIP" version. Customers who already own "HFA" OpenStage phones can ensure these are compatible by performing a firmware update. OpenStage "TDM" models are not supported by nfon.
- When using the phone for the first time an NFON Deployment PIN must be entered to establish a connection to the NFON telephone system. For more details please refer to A. Initial operation / 1. Requirements.
- There is currently no access to the main directory for the telephone system.
- Unify OpenStage phones provide no system menu access (XML).
- At this time there is no CTI client for Unify OpenStage phones.
- Unify OpenStage phones are available in ice blue and lava.
- The Unify OpenStage 20, OpenStage 40 and OpenStage 60 are also available as Gigabit versions. This is indicated by the "G" in the product name.
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.
- 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.
When disconnecting
When disconnecting the connection between the end device and the telephone system, it can take up to 60 seconds for the call forwarding to work. Once the end device is reconnected to the telephone system, it can take up to 60 seconds for it to register.
Call forwarding codes
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 |
| **13 | Cancel call forwarding if busy |
| *14 + destination | Call forwarding if unavailable |
| **14 | Cancel call forwarding if unavailable |

The Completion of Calls on No Reply (CCNR)
The Completion of Calls on No Reply (CCNR) creates a callback in case a person cannot be reached (e.g. the person is not on its desk or busy) at the moment.
To use this function
To use this function, the CCNR function has to be enabled in the administration portal and in the phone extension. Click on the CCNR check box under Administration / Profile to activate the function.
Activate a callback
A caller generates automatic connection establishment within the private branch exchange (PBX) to a previously busy party (only internally). If the the other party cannot be reached, the caller can use the callback function.
- In order to activate the function, insert *5 into your key pad. An acoustic confirmation will finalize the activation.
- As soon as the other party is available again, your end device receives a callback generated by the PBX. As soon as you answer the callback, the PBX sends out a call to the number you tried to reach initially.
Generating Callbacks
A caller generates automatic connection establishment within the private branch exchange (PBX) to a previously busy party (only internally). If the the other party cannot be reached, the caller is able to use the callback function. In order to activate the function, insert *5 into your key pad. An accoustic confirmation will finalize the activation. As soon as the other party is available again, its end device receives a callback generated by the PBX. As soon as the other party answers the callback, the PBX sends out a call to the initial caller and establishes the connection.
Erase Callbacks
- If the callback is no longer needed, all call backs can be erased by entering the **5 code into the key pad. An acoustic confirmation finalises the erase.
