5. Gigaset DECT system, how to configure
Here we describe the configuration/installation of the Gigaset DECT system to be used together with teams.
Firmware upgrade: Upgrade the system to the firmware 2.52 or higher
Option 1: First configuration via upload of provisioning file: You need a minimum configuration to start with Microsoft Teams, we have made it easy and created an provisioning file for you.
Download the following provisioning file that contains the settings you need:
!!!Do not modify this file!!!
Click here to download the provisioning file:
| Upload the provisioning file: The provisioning file can be uploaded via the web-interface. Open the Gigaset DECT system web-interface: Go to SETTINGS - System - Provisioning and configuration, click on Browse | ![]() |
| Select the provisioning file, click on Upload. | ![]() |
| Click on Start auto configuration | ![]() |
Option 2: First configuration via GRAPE In GRAPE:
| ![]() |
| ![]() |
Add an DECT handset: Go to: SETTINGS - Mobile devices - Administration Select as VoIP provider "Microsoft Teams onboarding" It can be that you see the VoIP provider "Microsoft Teams onboarding" 2 times, both can be used. | |
After successful registration, the handset is configured and will show on the display: This is an Microsoft Onboarding SIP account, that is used to sign-in the user account. It is not possible to make or receive calls with this account. | ![]() |
5.1 Softkey for Sign-in/out

Handsets that have completed the on-boarding, need to be able to Sign-in/out. For this, you need to assign an "Sign In" softkey.
- On the handset, long-press on the left or right softkey to open the Function List
- Go to More functions...

- Select Sign In

5.2 Handset Sign-in
- For Local Sign-in/out, the user needs to press the Soft Key "Sign In" to start the Sign In procedure.

- On your DECT handset you will see the Microsoft pairing URL and the Pairing code needed to login.
or
or ??? URL is provided by Microsoft !!! - The Sign In process is now done on a PC or device with an internet browser.
Open the pairing URL: showed on your screen
Enter the pairing code: (The code is not case sensitive)
Sometimes you need to login first an then enter the code
- Click on Next and select your Microsoft account.

- Microsoft will send an SIP Notify to you system (Onboarding account), that starts the handset provisioning.
It can take a few minutes before provisioning is started. If the procedure is successful, you will see your user-name depends on the user configuration in the display.
5.3 Handset Sign-Out
- You can Sign Out by pressing the Softkey "Sign Out"

Microsoft will send an SIP Notify to you system, that starts the handset provisioning.
It can take a few minutes before provisioning is started. If the procedure is successful, you will see "Sign In" on the display.

5.4. Increase audio quality (G.722 codec)
By default the audio codec G.711 is used.
If required, an higher audio quality can be achieved by enabling the G.722 codec. (Enabling the G.722 codec will change the maximum of parallel calls to 5 per base)
- In the DECT system, go to: SETTINGS - telephony - Audio - Enable: Wideband with codec G.722

- Activate the G.722 codec for the Provider or PBX profiles with the name - Microsoft Teams signin (Do this for each Provider profile with this name if multiple available)

5.5. Internal number dialing
In Microsoft teams the user has one phone number and that is the external number. For internal calls, the full external phone number must be dialed.
Using the Area code feature in our DECT solution, internal numbers can be dialed where the system will automatically convert this to the full external number.
Example:
Phone number = 0049 2871 1234500 - 0049 2871 1234599
- In the web-interface go to: SETTINGS - Telephony - Call settings
Enter the Area Codes, conform the company number.
- Instead of dialing the full number example: 0049 2871 1234500
The user can dial 1234500 - If needed, the local Area code can be increased to be able to dial internally using even less digits.
5.6 Auto-provisioning web-interface options
From software 2.53 or higher, the web-interface has the following provisioning options:
- Handset provisioning URL
- Last provisioning request date and time
- Start auto configuration
In the web-interface go to: SETTINGS - Mobile devices - Administration - Edit handset - Provisioning and configuration.
This is only visible for handsets using the Teams provisioning.

7. FAQ
| Which SIP/HTTP user-agent is send? | By default the user-agent contains: FAQ - User agent
Microsoft only wants to see the:
For this solution, the correct user-agent is set via provisioning. |
| When I have an integrator with multiple DECT Managers, do we need to change the user-agent via auto-provisioning so that every device uses the same user-agent? | No, the user-agent is changed by auto-provisioning to send only the device type and software version and is also valid for an integrator solution. |
| What is an Microsoft onboarding SIP account? | Each device that is not logged in Teams, get's an Microsoft Onboarding SIP account. This account offers an active SIP registration to the Microsoft platform. It is not possible to make or receive calls using this account, it is needed to start the Teams login. |

| How is provisioning started? | Provisioning is started by the Microsoft platform using the Onboarding / Sign-in SIP account. Via an SIP Notify send by the Microsoft platform using the active SIP account, provisioning is started. If the SIP account is not registered then provisioning can not be started. The SIP Notify is send by the SIP platform where the handset is registered against. (The active SIP registration normally keeps the firewall open.) |
| Who generates the text on the display during sign-in/out? | The text "Signed Out Successfully" or the URL to Microsoft with code is generated by the Microsoft platform using the xHTML/RAP protocol. |
| The URL for login is different then described on this wiki. | Always use the URL that is displayed on the DECT handset as Microsoft sometimes makes changes that could results to use another URL. The URL on the handset is coming from Microsoft and is the only valid URL. |
| Sign-in is not working | There could be multiple reasons
