Hi Expert there,
I just deployed new Openfire server for internal use.
Everything running well except “Dial Phone --> Computer to Computer”.
User between LAN can make Phone called and user between Internet also can make Phone Called.
But user from Internet unable to make Dial Phone to LAN and user from LAN also unable to Dial Phone to Internet users.
Error log sometimes said about Firewall blocking, or remotely closed, etc…
Anybody know how to fixed this issue?
Please advice me. Thank you v much.
