“architecture” of the call?

I searched for links and images but found nothing that would answer that. I wanted to understand: What is the “architecture” to make a call?
E.G: Softphone initiates call -> sends to asterisk -> asterisk unzips data …

I think I may be searching for the wrong term. It would be of great help to my understanding if you could explain!

Thank you all and good day :slight_smile:

Assuming it is SIP call, this is the call flow the word architecture it more related to low level programming

Yup, that solves to me. Thanks :slight_smile:
