A technical glitch in Rhode Island's E-911 system led to a 45-minute outage. State police say the difficulties occurred Wednesday morning between 9:30 a.m. and 10:15 a.m. Thirty-six people tried to call 911 while the system was disrupted. The operators could hear the callers, but the callers couldn't hear the person responding. The operators were able to use caller ID to call them back from a landline and assist them.
