microsip settings to work with elsix?

Question

Asterisk

I can't figure out how to set up MicroSIP to work with Elastix
. What do we have?
Server: Elastix (fresh)
ip 192.168.2.100/24 ​​(gw: 192.168.2.4)
provider authorization type: with registration
configured for the powertelecom.ru provider according to the instructions,
made the settings only from this instruction and so far have not touched anything else (apparently something then it is still necessary).
I'm trying to check the connection through MicroSIP and I can't match the fields in any way.
From communication with the provider, it became clear that we have a registration on their server.
PS Gentlemen, I'm very new to telephony, make a discount.
PSS If you need something from the information - write, I will send it.

Answer 1

Have you created an internal number (100)?
