Polycom SoundStation 2 Config

How does one access the admin for Polycom Soundstation2 conference phone.

Its already connected to some Trixbox on the network and has an extension assigned to it and I can ping it.

Question is how do I access the end point and point it to my new Asterisk server ?

Web GUI ? What port ? Console

All the info you will ever need-
