Hello...

never write private emails. They will be simply discarded.
Sorry Daniel i did not realize that i was sending the email to you
ngrep gets the traffic before the firewall. Do you have a firewall?
No i do not have a firewall. This is so weird!
start kamailio with log_stderror=yes and debug=5. if you don't see any sip message processing, then sip traffic does not reach the application layer.
I do have log_stderror=yes and debug=5 and i do not see any message and no any answer to my REGISTER, am i missing something in my script? (in the initial message of this thread you can see the kamailio.cfg)
Cheers, Daniel

Hello, I'm having problems with my kamailio, my phones are unable to register into the Proxy. I have been checking with ngrep-sip and all i'm receiving is many REGISTER from the phones but never getting some response from the Proxy The Proxy has a public IP and the phones are behind NAT. The weir thing is that my logs are not showing any output...and as you can see on the script, i have a section to receive REGISTER requests.... if (is_method("REGISTER")) { if (!save("location")) { sl_reply_error(); } exit; }
If everything is fine, then no log message should be printed if debug parameter is low.
But i should see in the Kamailio logs the answers, right? or i have to configure this on the scripts?
My debug is on "3"
But if you run in debug mode with a high value and nothing is printed, then the SIP traffic does not reach the>application. A reason for that might be a firewall, do you run one?
The SIP traffic is arriving the machine (at least), i have checked this with the ngrep on the server running kamailio:

And i never gets a response from Kamailio, for example, a 200 OK, or a 407 unauthorized...
What can i do?
