Hello, we have for Asterisk servers, and all works fine. But in a few cases we need to register sip phones in one asterisk server from another place, and we can´t register. All the ports are open and redirect to the ¿correct? ports (5060 tcp, and the range we have defined in the phones for udp) in the router, but we can´t register the sip.
Is there any file to configure to solve this problem? Thank you.
Hello, thank you for your reply. I have registered the sip phone adding the line nat=yes and using a stun server (stun.ekiga.net) but i can hear the other person, but he can´t hear me. What can I do?
