Set the electric parameter in digium hardware


i’d like to set the electric parameter for my digium hardware.

Some people tell me that his phone doesn’t work fine after the installation of digium analog board.

It seems that the ring tones are lower than the previous pbx… but the phone is tha same.

The phone has a long cable (200 meters)… may I increase the power supply for this phone?

If this is not useful… can I anyway set the electric parameter for the analog board?

I don’t need to increase the volume settings.



it is simple, you bring phone to a place where near yhe server? see what will happen?
i think, if i am not wrong, there is a hardware or physical setting for that.
