ATT 993 Speaker Phone and Ringer Quiet with Obi200

[JonathanK]

Hi,

I have a Obi200 connected to an ATT 993 2 line phone. The speaker phone and rigner work great on a analog line. When connected to the Obi200 they both are quiet. I assume I can boost the voltage somewhere, I saw a few options that might do it, but I wanted to check here first to make sure I was on the right track.
