I’m totally new in Freepbx and started exploring it from last 7 days. Server is working fine able to make calls between extensions from outside network also working fine.
Problem started when I configured Twilio URIs by proving my public address. After that I’m getting constant incoming call from unknown extension. Have anyone face the same issue then please guide me how to solve it .
I tried to follow your advice to close 5060 Port but after closing my all the remote phones were disconnected. So I change port number and open that port again.
