How to link phone calls to IP PBX with DB?

Question

PHP

Good day. The bottom line is that you need to implement such a scheme:
1) A person calls the phone
2) The server receives a call to the phone
3) Records the person in the database
4) The person in the call center answers the call or calls back
I read that this can be done using IP ATC. Normal guides how to do this - did not find. What do you need to use for this and do these ATCs have any APIs?

Answer 1

The easiest way is to buy a cloud (virtual) IP PBX from a telephony provider, there is plenty of functionality out of the box.
A little more difficult - set up Asterisk, take a SIP number and manage calls yourself, there are actually plenty of guides on Habré

Answer 2

In an asterisk, it is done using DB_EXISTS (to its native database). The setting of this depends on the logic of the exchange as a whole. That is, it is impossible to say exactly how it should be done in your case. In general, look towards https://wiki.asterisk.org/wiki/display/AST/Functio...
