> A typical server has local users. And often the server allows incoming calls from other SIP servers that can not be authorized.
> Therefore, anonymous must be allowed on the server.
> But if someone makes a call using my domain (from), why should the server allow such a call without authentication?
> https://blogs.asterisk.org/2018/02/07/identifying-endpoint-pjsip/
> The way anonymous@<domain> does not solve this problem.
> The solution would be to be able to create some anonymous at other or anonymous at external that would be used for "others" or "non-local".
> Another solution would be to add the anonymous_disable=yes option to the DOMAIN_ALIAS section
> But it's not easy for my level of programming. I just added just one line to the code (patch attached), which forces authentication of anyone who dares to specify my local domains in the from field
