Bell wont ring loud

[timeshadowrider]

Hi Everyone,

I have one of these phones I would like to use with the Obi, I have a Obihai 200 it will ring the bell really quite but it wont light up the LEDs in the phone. Is there a setting I need to change to send more power to the phone. It rings the same even if it is plugged right into the unit of if the unit is plugged into the wall and its plugged into another jack in the house.

Picture of phone:

Any ideas??

Thanks

Physical Interfaces, Phone Port, Ringer, RingVoltage can be increased from the default  (70?). But may not give much increase in ringer loudness.
