How should a dispatcher handle a silent call (no voice) from a 9-1-1 line?

• A. Ignore the line until it becomes voice
• B. Attempt callback, triangulate location using ANI/ALI; if possible, attempt to speak with caller; monitor and escalate if needed
• C. Immediately disconnect and mark as prank
• D. Transfer to another agency without any notes

Answer: (B)

When a 9-1-1 line is silent, treat it as a potential emergency that requires proactive locating and information gathering. The best approach is to immediately attempt a callback and use available call-identification tools to locate the caller. ANI/ALI helps identify the originating number and its location, so you can guide responders even if the line is quiet. If you can reach the caller, try to speak with them to determine what’s happening, their safety, and any immediate needs, while keeping the line open long enough to gather crucial details. If you can’t reach them, continue to monitor the line, use location data to estimate where help is needed, and escalate to field units or a supervisor as appropriate, ensuring that the call is documented and resources are deployed. This method prevents missing a potential emergency and provides a path to locate and assist the caller, rather than ignoring the line, prematurely ending the call, or transferring without notes.
