How to synchronize Mango Telecom and amoCRM?

Question

Telephony

The company works with Mango and their online PBX. Then AMOCRM was connected, but it could not synchronize with Mango, so a crutch was connected - OnlinePBX.
Now we have such a scheme - we pay for communication, PBX and numbers in Mango, he transfers everything to PBX OnlinePBX, we also pay them, and then everything goes to CRM. How can this path be shortened?

Answer 1

telefum does it all
update onlinepbx does it better.
telefum turned out to be a bit buggy

Answer 2

Now Mango and amocrm are friends through "Simple Calls"))
