Why do these Cisco/Linksys ATA's have some stupid defaults? I just played with (er, configured) another one over the last weekend.
I always (have to) change the default ringing voltage in these Cisco/Linksys ATA's from 85V trapezoidal to 90V sinusoidal, so that an attached phone will ring reliably. I don't know for which part of the planet (if any) their default is intended. From the standards I've studied in the past, the trapezoidal waveform especially doesn't ring a Bell.
