Registering Fritzbox 7490 with W52P

Hi There

Can you please help me enter the correct settings in the Yealink W52P so I can use it with the Fritzbox 7490.

I have attached a screen shots of one of the settings I have tried already, I have tried multiple combinations of Register name and User name.

Also attached are the settings I have from the Fritz box.

Thanks in advance for any help received

Rufus
