I've found several devices that are able to detect the sound of
gunshots and can raise the alert by telephone or other methods. Below
are brief descriptions of these devices, with information that will
enable you to contact their distributors.
======================================================================
ShotSpotter:
"ShotSpotter?s gunshot location technology is based on acoustic
detection of gunshot sounds. Unlike optical (muzzle flash) detection
techniques, acoustic techniques do not require the shooter to be
located in the field of view of a sensor. An acoustic system can cover
a much larger area than an optical system and is thus most appropriate
for neighborhood policing.
Acoustical techniques work by detecting the muzzle blast. The firing
of a gun creates a loud, impulsive sound of up to 160 dB SPL that can
be heard up to two miles away from the firing location... ShotSpotter
detects gunshots by listening, replacing the citizen?s ears with a
network of sensors. (Although these sensors pick up the characteristic
'crack' of a gunshot, they do not detect or record the much quieter
human speech.) By detecting the gunshot on multiple sensors,
ShotSpotter can quickly and accurately determine the location of the
shooter."

Shotsfired, by Traptec:
"This sensor identifies the acoustic and ultrasonic signatures of a
firearm discharge. Two models have been developed to accommodate
demand for mobile (police cars, armored trucks, taxi cabs, nuclear
waste delivery trucks, etc.) and permanently affixed units (banks,
schools, convenience stores, etc.). Each unit relays to appropriate
personnel when and where a discharge occurred, how many shots were
fired and, with future enhancements, information on the type of weapon
used as well as the unique signature of the weapon for evidentiary
purposes. Like the Taggertrap, each unit may be programmed to activate
alarms, cameras, or other security systems. The mobile unit, in
particular, may facilitate monitoring the suspect's movement through
GPS...
Current competitors limit their systems to the detection and
triangulation of a loud report. Yet, their systems are unable to
distinguish between a true gunshot and a firecracker, backfire, or
blowout. Thus, the only reliable support for gunshots remains
eyewitnesses. Traptec's patent, however, affords it the exclusive
ability to isolate the sound and identify it as a firearm is
discharged. Accordingly, Traptec maintains an invaluable competitive
edge over others in the marketplace."

This product is still under development:
"The On Alert Gunshot Detection System (GDS) can be embedded in
high-crime or battle areas and quickly responds when it detects
gunfire... GDS combines acoustic sensors, transmit/receive components,
computer chips, an integrative motherboard and a power source into a
wireless package. The technology is packaged in two models, one for
civil authorities and the other for military personnel. Proxity
Digital Networks, New Orleans, is developing the system under a
licensing agreement with Synchros Technologies Incorporated, Bixby,
Oklahoma...
The civilian model in development is a small, wireless self-contained
unit that is powered by lithium batteries and backed up by solar power
when the batteries recharge. The sensor prototypes measure 14 inches
long, weigh approximately 2 pounds each and are designed for
omnidirectional coverage estimated at 400 yards. Proxity is working to
reduce the sensors to the size of a pager. On Alert can be clipped to
power lines, hung from street lights or placed in trees."
