How to organize a call to a person and drop the call when he answers in PHP?

Question

SIP

Good day, I'm trying to deal with SIP telephony.
You need a php code that logs in with any SIP operator and calls $tel = '79000000000'; without audio recordings, a simple reset when the subscriber answers (this is necessary for the person to enter the last 4 digits of the number from which he was called)
That is, the task:
authorization data to connect to another operator)
- call through it on the phone
- reset the call (but this is not necessary)
Rummaged through the whole Google, Yandex. The last hope for the forums.

Answer 1

1. Take a provider that can close the call with different numbers (if you need to show different 4 digits at the end)
2. Set up Asterisk
3. Connect to Asterisk via AMI and send / end calls via AMI commands, writing code in the language in which you write
The first thing that came to mind
