ast_sockaddr_resolve: getaddrinfo(): Name or service not known

Question

I have got this error:

ast_sockaddr_resolve: 
Getaddrinfo("df7jal23ls0d.invalid", "(null)", ...): Name or service not known

In Asterisk PBX.

All registration process with asterisk is successfully done. After that when I hit the call button of my application it shows the above error.

Here are my logs:

Answer 1

That mean you incorrectly setuped your server.

Server should have correct resolvable dns name OR have be record in /etc/hosts pointing your name to ip.
