What can be used to route VoIP traffic from different providers?

Question

Telephony

Hello, in the process of developing the service, I encountered the task of collecting statistics on calls and listening to the recordings of conversations.
Let me explain with an example, there is a service that is a highly specialized crm. The question arose of collecting statistics on calls.
The user of our service has a softphone on his computer, which is connected to someone else's telephony (Mango, Beeline, Sipuni, etc.). The user makes outgoing and incoming calls, our service, in turn, must receive information about the duration of these calls and store a record of this call. There can be many users on our service, and everyone can call through different providers.
Accordingly, how can you receive information on calls made by clients of our service, while the client is ready to provide details and other data.
I found information about Asterisk, but I don’t quite understand if I’m digging in the right direction.

Horror and nightmare, urgently rephrase the question into a more adequate form of the question, it is completely incomprehensible what you want.
