Ahh, he's talking VoIP <-> FXO adapters, not VoIP <-> FXS adapters,
which is what I'm sure we all thought when "ATA" was mentioned.
Robert - there are ways around this on analogue lines, involving things
like line polarity reversals on answer, call progress detection, etc.,
but they're all pretty flaky - you're better of with digital interfaces,
eg. BRI or PRI.
Ask asterisk-users about them, not asterisk-dev - this is not a problem
with the code, but with your configuration.
