Having worked 9-1-1 dispatch I can guarantee you that hanging up on a distress call would get you fired.
Thank You for Your work and information.
2 weekends ago the stepdaughter was in an accident with someone running a Red Light and hitting the car she was driving (as the Designated Driver) she called 911 and got put on Hold and that turned into Ignore after 3 minutes. The 911 system was the one for CMPD (Charlotte/Mecklenburg City PD/ County Sheriff) and the LEO’s arrived and she was still on Ignore so she hung up on 911.
Not uncommon for them from what we know about the system in Charlotte.
