What is the best way to combine CRM (SaaS) and Asterisk (each company has its own)?

Question

Asterisk

There is a SaaS-system, it is clear that in each personal account fields with the settings of their Asterisk are needed, but maybe there is a ready-made library with commands for Asterisk? For example, "call such and such a phone" or "get call history on such and such a phone number". Or maybe someone is ready to take on the creation of such))

Answer 1

There are two ways - AGI and requests to the database directly from the numbering plan.
