I am trying to set up a Merlin Legend R7 CKE3. For some reason when I insert the 012 Basic Telephone Module cards, I cannot get dialtone. I have two of them and neither of them are providing dialtone. If I hook an analog set into one of the modules, I hear clicking and then dead air. If I call the extension it is connected to, the phone doesn't ring but when I pick up, the call connects. However, no sound is transparent between the two telephones. Any ideas? I find it hard to believe that I may have two bad 012 cards. I have also tried to factory reset the processor and swap slots on my carrier to no avail. HELP! Thanks.
