Cant get incomin calls to work


I have just bought a did number from and im trying to get it to work with my Asterisk/FreePbx setup.

Im using FreePBX 2.10.0 and Asterisk 1.8.17
Here is the Sip-Trunk i have setup in freepbx.

I have also created an incoming route with everything empty.
Then destination :Terminate Call / Busy.

In i have bound my Did to “Custom Sip = MyAsteriskIp” and enabled sip trunking.
Must i bind the custom sip to an existing Sip Extension? I have tried this also but i cant get it to work either.

I get "The number you have dialed is not connected to a service"
Im expecting a busy tone.

Btw, MyDivert says sip device registered and it is my freepbx box.
Currently im only trying to get incoming calls to work.
