How do I use the NS1000BX WAN port for Sip line connection?

Pleas assist.

You need a license to use the wan port, it will have to be a different network than the lan/ phones

I just looked on the activation key window, there is a built-in router preinstalled activation. Is that good enough for WAN use?

It is a trial license for either 30 or 60 days. It will work once only
