Greetz Folks,

I have Quadro 6L FXO and i'm struggling to get our SNOM 300 phones to register with it.

Phones and quadro are on same subnet.

I've set up a user extension on the quadro and set the phone accordingly.

logs on quadro show:

Logs show phone is sending request, Quadro is receiving request but phone is not registering?

Please could someone help me where I've gone wrong.

Thanks in advance

Dave
