Abstract
In an enhanced 911 (E911) response system, a callback monitor including a microphone and a speaker is connected to a telephone. When a caller dials 911 from the telephone, upon the telephone going on-hook, the callback monitor is activated to allow a 911 operator who calls back to detect sounds from the location of the caller'"'"'s telephone without that phone ringing or being taken off hook. The callback monitor includes a timer; when the timer expires, the monitoring ends. In alternative embodiments, the timer can be extended.
