we have tried and been unsuccessful for 5 years or more to have communication failure calls to stop. this does not affect burglar alarm calls as interesting when we get communication failure calls we get a call about a burglar alarm, very interesting. There is no reason for these calls, since apparently your Technicians know of these problems. if your people do not know the difference between alarm calls and communication issues, you been better training of your personnel. if this does not stop the next call is to the government.
