Too bad. What is your router model?

Should try to set up a better firewall at the router level and use ports of your choice for incoming calls and registration.

Please also check your internal network PCs has problems such as viruses or other things.

My experience in the past was that hackers tried to come for a while and if your security has been strengthened, the chance of coming back is lower and less frequent. I also immediately put their IPs at the router level so that they were in no way to get a response from my asterisk. This is very important. Their IPs drop immediately means they know nothing of my side. They cannot try other methods.

In IP01, there is no way to set up like this. Also as a "server" or a linux based device, hacker already knows its existence.
