Online StoreRegistering the Aastra MBU-400 to 3CX
Ever since the Aastra MBU-400 hit the streets I have wanted to do a hands on article about this Dect solution. For around two months now this unit has been registered to the trixbox Pro server in our lab, so that on the rare sunny day in Buffalo we can field some calls outside, as well as
around the office.
The MBU-400 is one of the easiest to use Dect Phones I have ever had the pleasure to get my hands on. I have been able to get the unit registering and making calls on both of our featured PBX solutions (3CX and trixbox Pro) as well as trixbox CE, with no issues along the way. I will provide a quick walk through of the steps to get this unit running on all three systems.
3CX Registration Steps
——–
1.) The First thing you should do is create a new extension in your 3CX.
2.) Once the extensions is created, un-box your MBU-400 and physically connect the base station to your network. Once the base station initializes, power on the MBU-400 Handset. You will see a message which states that you must reset the gateway to allow the handset to automatically provision to the base station. Press the reset button on the back side of the base station, and allow the unit to restart. The Handset will then find, and register to the base station.
*NOTE*: For any additional handsets, this same process is followed. You can have up to 8 unique handsets.
3.) Now that you have a proper connection from the handset to the base station, it is time to tie the base station into your PBX. To access the base station’s web GUI, grab one of your handsets, and press the volume up button on the left hand side of the phone. This will display a quick Network status screen. From here you can see your Base Station’s IP address. Enter that address into the web browser of a PC on the same network as your PBX and base station.
*NOTE*: This IP address is for the Base Station only. None of the 8 possible handsets get their own IP, they share a single IP at the base station.
4.) When browsing to the Web GUI, you will be prompted for a username and password. The Aastra default username is ‘admin’ and the default password is ‘22222′.
5.) From the Web GUI, you can configure your phone exactly how you want to. For this article, I am going to keep it simple, registering the single handset to a single extension on our 3CX.
6.) Click on the ‘Account 1′ Link on the left hand side of your screen. You will see a screen 
similar to the picture provided. For each of the following fields, enter your settings as described below:
- Server is local – Unless this is going to be a remote phone, set this field to yes.
- Display Name – You can set this to whatever you want to display on the LCD.
- Account – Set this to the Extension number you intend to use.
- Password – Set this to your authentication password for this extension that you set in the 3CX.
- Account Name – Set this to the Extension number you intend to use.
- Account Mailbox Name - Leave this account blank.
- Account Mailbox Number – Leave this account blank.
- Registrar – Enter your 3CX Server’s IP address in this field.
- Outbound Proxy – Enter your 3CX Server’s IP address in this field.
- Authentication User Name – Enter the Extensions Authentication Username in this field
- Leave the rest of the fields as their default.
7.) Save your settings and reboot the unit. This most basic config will get your MBU-400 up and running on 3CX. You will have full call and voice mail functionality.
With those quick an easy steps you now have a fully operational DECT phone as part of your 3CX system. You can further configure the phone to your desired setup from this point, but unless you require certain changes to be made, you should be completely finished with this process.

Thanks for the tutorial, but I have question regarding the quality of the FXO interface on whether or not there are echo problems like many other devices out there (e.g. Handytone 503, SPA3102, etc.)
Mustafa,
I have tested the Line port on this and I did not experience any echo. The PSTN Port also has a nice little Web Setting page itself, with a few settings like for example to fwd to an ext on busy.

This gives me a great step forward in getting my MBU 400 phones working with Trixbox Pro. I understand now that the SIP account is the MAC address with the Trixbox Pro, and the password is given to you… but I still get "Unknown SIP account" on the phone, and the Trixbox says my extension is not registered.
Could I have some help here? Thanks…
