provide a user interface comprising a map and a signal indicator, the signal indicator positioned on the map at the first location; and

receive a user selection of a geographic region on the map; and

a messaging interface to:

receive the selected geographic region from the web server, the selected geographic region associated with a message;

determine that the first location and second location are inside the selected geographic region;

determine that the first data signal corresponds to an unanswered emergency call and the second data signal corresponds to an answered emergency call; and

transmit the message to the first phone number associated with the data signal corresponding to the unanswered emergency call associated with the selected geographic region, the message being transmitted while the unanswered emergency call is on hold;

wherein the message is not transmitted to the second phone number based on the determination that the second data signal corresponds to the answered emergency call.

2. The system of claim 1 , wherein the first data signal is one of a plurality of data signals received by the data ingestion module, a portion of the plurality of data signals having locations inside the selected geographic region, and the messaging interface is configured to transmit the message to at least a subset of the portion of the plurality of data signals having locations inside the selected geographic region.

3. The system of claim 1 , wherein the messaging interface is configured to transmit the message as a short message service (SMS) message.

4. The system of claim 1 , wherein the web server is further to receive the message from the user.

5. The system of claim 1 , wherein the web server is further to provide, in the user interface, a plurality of selectable message segments, and the message comprises at least one of the message segments selected by the user.

6. The system of claim 1 , wherein the data ingestion module is to receive a third data signal comprising a third location and a third phone number after the web server receives the user selection of the geographic region, and the messaging interface is to:

determine that the third location is inside the selected geographic region; and

transmit the message to the third phone number.

7. The system of claim 6 , wherein the message is associated with a notification time period, and messaging interface is further to determine that the third data signal arrived before the notification time period elapsed.

8. A method for sending outbound messages from an emergency system, the method comprising:

receiving a first data signal comprising a first location and a first phone number and a second data signal comprising a second location and a second phone number, the first data signal corresponding to an unanswered emergency call that is on hold and the second data signal corresponding to an answered emergency call;

providing a user interface comprising a map and a signal indicator, the signal indicator positioned on the map at the first location;

receiving a user selection of a geographic region on the map;

receiving a message associated with the geographic region;

determining that the first location and second location are inside the selected geographic region;

determining that the first data signal corresponds to an unanswered emergency call and the second data signal corresponds to an answered emergency call; and

transmitting the message to the first phone number associated with the first data signal corresponding to the unanswered emergency call associated with the selected geographic region, the message being transmitted while the unanswered emergency call is on hold;

wherein the message is not transmitted to the second phone number based on the determination that the second data signal corresponds to the answered emergency call.

9. The method of claim 8 , wherein the first data signal is one of a plurality of data signals, a portion of the plurality of data signals having locations inside the selected geographic region, the method further comprising:

identifying at least a subset of the portion of the plurality of data signals having locations inside the selected geographic region; and

transmitting the message to phone numbers associated with the subset of the portion of the plurality of data signals.

10. The method of claim 8 , wherein the message is a short message service (SMS) message.

11. The method of claim 8 , further comprising:

providing, in the user interface, a plurality of selectable message segments; and

receiving a user selection of one of the plurality of selectable message segments, wherein the message associated with the geographic region comprises the selected message segment.

12. The method of claim 8 , further comprising:

receiving a third data signal comprising a third location and a third phone number after receiving the user selection of the geographic region;

determining that the third location is inside the selected geographic region; and

transmitting the message to the third phone number.

13. The method of claim 12 , wherein the message is associated with a notification time period, the method further comprising:

determining that the third data signal arrived before the notification time period elapsed.

14. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to:

receive a first data signal comprising a first location and a first phone number and a second data signal comprising a second location and a second phone number, the first data signal corresponding to an unanswered emergency call that is on hold and the second data signal corresponding to an answered emergency call;

provide a user interface comprising a map and a signal indicator, the signal indicator positioned on the map at the first location;

receive a user selection of a geographic region on the map;

receive a message associated with the geographic region;

determine that the first location and second location are inside the selected geographic region;

determine that the first data signal corresponds to an unanswered emergency call and the second data signal corresponds to an answered emergency call; and

transmit the message to the first phone number associated with the first data signal corresponding to the unanswered emergency call associated with the selected geographic region, the message being transmitted while the unanswered emergency call is on hold;

wherein the message is not transmitted to the second phone number based on the determination that the second data signal corresponds to the answered emergency call.

15. The computer-readable storage medium of claim 14 , wherein the first data signal is one of a plurality of data signals, a portion of the plurality of data signals having locations inside the selected geographic region, and the instructions further cause the processor to:

identify at least a subset of the portion of the plurality of data signals having locations inside the selected geographic region; and

transmit the message to phone numbers associated with the subset of the portion of the plurality of data signals.

16. The computer-readable storage medium of claim 14 , wherein the instructions further cause the processor to:

provide, in the user interface, a plurality of selectable message segments; and

receive a user selection of one of the plurality of selectable message segments, wherein the message associated with the geographic region comprises the selected message segment.

17. The computer-readable storage medium of claim 14 , wherein the instructions further cause the processor to:

receive a third data signal comprising a third location and a third phone number after receiving the user selection of the geographic region;

determine that the third location is inside the selected geographic region; and

transmit the message to the third phone number.
