Features of snom® desk phones
This article is about the features of snom desk phones and how they interact with the services and features of One Net Business. Information applies to the snom 715, D717, D725, D735, D765, and D785 unless stated otherwise.
How does my desk phone interact with One Net Business?
There are several features of your desk phone that interact directly with One Net Business.
- You can use Feature Access Codes (FACs) to do tasks including pulling a call onto your desk phone, parking a call or switching call forwarding on and off.
-
Some buttons of your desk phone interact with specific One Net Business services.
Show me an example
For example, when you press the DND (Do Not Disturb) button on your desk phone, your availability changes to do not disturb for all your devices and locations. If you change your availability in another location, for example in the One Net app, your availability is also changed on your desk phone.
- Your desk phone has direct access to your One Net Business call history and your organisation's phone book, so you always see the latest information.
-
You can personalise the programmable buttons of your desk phone using One Net Manager.
- Your desk phone can display the caller's name for incoming calls (if the name is in your organisation's phone book).
Buttons of snom desk phones
Your snom desk phone has buttons that you can personalise, called programmable buttons, and buttons that you can't personalise.

Personalising is choosing which functions your programmable buttons do. Your administrator personalises desk phones in One Net Manager. The settings are part of your configuration file.
Buttons that you can't personalise
Buttons that you can't personalise have a fixed purpose and usually have a word or image printed on them.

Buttons that you can personalise - programmable buttons
Programmable buttons don't have a fixed purpose and are usually blank. There are two types:
- Function buttons
- GUI function buttons
Your administrator can personalise programmable buttons for you.

Don't personalise buttons locally on your desk phone
Your desk phone downloads and refreshes your configuration file every day. This means that anything you set locally on your desk phone, using the phone's buttons and menu, will be deleted.
Always ask your administrator to personalise your desk phone in One Net Manager.
