Has anybody else who has bought one of these, had any reliability issues with it? I've had one in use for less than a month. I returned home to find the phone line dead, and the True Call unit rapidly alternating between its front Red and Green LED's. Resetting the unit by cycling the power made no difference, the only way I could get the phone back was to bypass the unit and plug the phone back in the main socket. True Call support, stated that its a 'software fault' and the unit needs to be returned. I'm a little disappointed given its price tag that its not managed to survive in use for longer than a month. Just wondering whether its a widespread issue or whether the unit has just taken an intense dislike to me .
