We have 2 sites that have CallPilots and MICS systems that are having problems. The CP's at both sites will intermittently quit working. We started by changing the power supplies but that didnt fix it. We then changed out the CP at the first site and it still intermittently quits. We then moved the DN the CallPilot was connected to and still no luck. We changed the CP at the second site yesterday and its not talking this morning. Is there something wrong with the MICS? Ideas? Thanks.
