How to create a smart autoresponder?

Question

Asterisk

Hello!
I have a task to create an autoresponder-dispatcher about the location of cars. Location data (everyone's current address) is available and constantly updated on a remote web server. Getting them from there is not a problem with an http request, for example.
Other equipment: an Internet-connected server with a gray IP (regular PC) with Ubuntu Server, a mobile phone (or USB modem if necessary), a SIM card with a number that users should call.
The problem for me is how to link it all (at least in my head). I understand that the answering machine can somehow be made based on Asterisk. I drowned in an abundance of manuals ...
Can you tell in the most simple language where to dig to do something like this:
1) the local server regularly takes text data about the location of cars from a remote web server and stores them on itself until the next. updates. (this is understandable)
2) If someone calls the SIM card number, the server picks up the phone, selects certain wav (or any other) sound files and plays them to the caller in turn.
3) Hangs up.
If it will be possible to give the calling user a choice (press button 1, button 2, etc.) - that's great!
How to do it, on what basis? Thanks for any explanation!

Answer 1

1. A computer with Internet access for Asterisk, non-critical hardware, Ubuntu Server or Debian.
2. GSM gateway, such as GoIP.
3. A script, for example, in perl or php, which will periodically collect data about car addresses and convert them to wav / mp3 through a festival or other synthesizer.
4. Simple dialplan - accept a call, wait for a button to be pressed, play the desired file. If you do not wait for the button - play all the files in a row.

modem support
if Megafon, then it is possible through a multiphone.
but in general, with such questions it is better to find a person who will do everything

Answer 3

Of course, this is done on the basis of Asterisk. But based on the task and questions, I recommend hiring a specialist.

Answer 4

1. Asterisk
2. GSM gateway - I do not recommend modems (unreliable)
3. Script (AGI in the understanding of asterix) that either collects a phrase from files or calls an external service to generate phrases based on text.
4. Not a complicated dialplan.
But you better hire a specialist.
If I can help in more detail.
