Does anyone know the pin outs for the Polycom Sound Station I.

It has an 8 pin lead and I can't find any info on it.

I can draw dial tone on the 4 & 5 pins but the dial tone fades away in a few seconds.

If I add a jumper from pin 5 to pin 8 I can hold dial tone but then I can't break dial tone to dial anything.

Any ideas?

I have the power supply and it has its RJ45 intact, the color code you refer to is correct.

My problem is knowing what pins do what on the Polycom side.

I opened one up and measured the voltage. You can see my Pinouts Here: www.riddledtv.com/forums/polycom-soundstation-wall-module-power-supply-t2708.html

Thanks,
How did your repair work out?
