That's the problem, I don't have a POTS Phone.....

It has a pinhole, and I did the factory reset, but I still don't know the
default IP address to acces the web interface. It has one, but I haven't been
able to find the default addres anyplace. There's a MAC address and some more
numbers on the bottom of the device. Is there a way to figure it out using
that?

Thanks for any help!
