I am connecting our new VOIP system to an analog phone using SPA112. It appears the output voltage is way too low. Caller ID appears, but it is not even strong enough to make the phone ring.
The call sounds very faint as well.
I tried upping the FXS Port Output Gain to 2. That made it slightly better, but still not enough to make phone ring and sounds distant, etc.
Thanks for any help.
