Hello everyone, I am pulling my hair here because a carrier threw me curve
early today.
They want to send calls to my asterisk server using SIP. Then they said
that their gateways don't have to register with my server, that all they have
to do is send a prefix for validation. Whereas
What they're asking you to do is quite insecure to be doing over public IP. At the very least, you should confirm that there is a static IP that these calls will be coming from and only accept calls from that IP, but that's still not quite as secure as digest authentication that would be available
