I have a question:
I try to use linphone (ios and android) to connect to my
Asterisk server on the Internet , I set the user , password and
domain to my account.
Using the 3G network SFR over TCP, I can not login .
If I set the proxy to sip.linphone.org , it works.
Why my server can not receiving SIP messages directly ? What is
the difference through the proxy?
I have no problem going through free , bouygues ...
