i currently dont have a 'spare' land line , but i got 3 wireless phone and the internal intercom is good on all 3, i check the wall socket, not plugged into the hub. that is connect correctly. i traced the phone cable and that intact no kinks or nicks. I power cycled the phone master base and no difference
i cant make outgoing and incoming say line busy, but there no dial tone and no sound it 'connect' after dialling and just silence
i was hoping that tech support could just power cycle the connect card, i get hold of a 'backup[' land line soonest
