ATA call incoming ,but phone not ringing

[oba]

I can`t make my phone ringing.I try couple of phones,no one working. Changed ring voltage and frequency in different combination's, but still not working.Please help.If I answer the phone I can speak with the other person, but the phone is not ringing.I have to guess when somebody is calling me.

It's usually related to the line voltage when this happens...
I think each FXS can be set separately, so double check to be safe.

If you have a cordless phone, try that and see if it rings. (Having it's own power-source can avoid some of the line-voltage related issues.)

I'll let the guys with ATA experience give you a suggested line voltage setting, but I would suggest that you power-cycle the ATA after changing the voltage, just to be on the safe side that the setting changes have been read.
