FreePBX + multifon + outgoing?

Question

Asterisk

Good afternoon!
I can't set up outgoing communication via multiphone on FreePBX.
(Incoming works fine)
If anyone has a working system, show how outgoing routing is configured.
Well, not only that, I would also like to see how the trunk is configured.
When dialing, I get beeps (seven pieces), and then a female voice says that all sockets are busy.
Of course, the call never comes.
Google looked through, there are a lot of options, but none of them worked.
Stayed in two rooms.
Authorization lines wrote different. - nothing helped.
