SIP request (REGISTER) from MY IP was rejected. Reason: Block WAN requests is ON. .
I installed the "3CX Hosting" version, but I can't access my SIP via MicroSIP for Windows. I read that I need to disable blocking, but I don't have that option. What should I do?
 
Sounds like you've attempted to register the SIP with 3rd party incorrectly and got yourself blacklisted.

Assuming youre on hosted and cannot access the blacklist feature. Therefore, you have to wait.

I would advise using the 3CX Apps to easily access your extensions.
