I'm having a huge problem getting an MICS running 6.1 XC with a CLID card to display anything but "line 00X" on incoming calls. This occurs at the prime set, and any other set even after entering f811. Waiting for 2nd or subsequent rings has no effect. Yes, I have checked and changed the programming option for 1st display from line to name to number and back again but all that ever appears is "line 00X". I have also put a stand alone CLID phone in line just prior to the MICS connection and I get full caller ID on that set so I know the service is active and working from the phone company.
