This
feature can be used to notify an “emergency responder group” within a business
that 911 has been dialed from an extension on the PBX, allowing those
internal responders to go to the location and manage the emergency until
Public Emergency Services personnel arrive. It also allows for
identification of “mis-dials” so that personnel can have additional
training to prevent false 911 calls in the future.
First make sure
that your Asterisk VOIP PBX can successfully email to the address* you wish
to receive these 911 alert messages. (i.e. send voicemail to email to test
that address.)
Make sure that you
have a working 911 outbound route as in:
Add the following
context to /etc/asterisk/extensions_custom.conf Replacing “911 call
from Extension” with your preferred email body text, “911 Alert at”
with your preferred email subject line text and email_address@you_want_to_send_to.com with the preferred
email address*.
Within
/etc/asterisk/extensions_custom.conf include the context under
[from-internal-custom] as in:
After reloading
asterisk, a 911 call will produce the following email message:
*(email address) The
above code will transmit to only one email address, that email address may
be a group address on an email server. On some email servers it is possible
to create one address that will “forward” to multiple addresses. It is
possible add additional email address “sends” to the above context code by
adding additional lines in the following format:
exten => 911,3,System(echo "911 call from Extension
${CALLERID(NUM)} - ${CALLERID(NAME)} at ${STRFTIME(%C%m%d%y%H%M)}" |
mail -s "911 Alert at ${CALLERID(NUM)}" additional_email_address@you_want_to_send_to.com)
As in:
It is also
possible to send emails from this feature to cell phones via text. Most
carriers have an email-to-text format i.e. AT&T email to text address
format = xxxxxxxxxx@mms.att.net (with
xxxxxxxxxx being the cell phone number including area code)
