Its not an issue, but a notice. Since I don't see it here with a TDM card, I can only guess that its one of two things: - your telco line is providing tip/ring reversal for answer supervision, or, - your tip/ring connection to the pstn in reversed.
Since the chipset on the TDM fxo module automatically handles tip/ring connections in either direction, best guess is that its the first item. You can verify that by placing a regular voltmeter on the tip/ring pair and watching it while placing a call. ------------------------ > I am in the US, NYC using a TDM400 card.
