Most people get echo issues with x100p's in the UK due to mismatched impedance, the newer TDM400P is much better, and you could get this with 3 FXO modules (otherwise known as a TDM03B I believe).

My apologies that I messed up a thread for my post - I had a message open and simply clicked on the link ... slap slap. Would anyone know of a better choice to multiplex three fxo lines into an asterisk box? I can still use three Digium X100P cards, but methinks, a seperate unit would be better.
