lolzzzz
till now i just tried Registration with TLS, today after this mail i
started testing INVITE and i also came across the same problem
let me explain my case. I have got two grandstream gvx3140 connected to
kamailio via TLS. via UDP i have successfully tested calls between each
other.
Now when i try to call 1000 from 1001, it gives me 404 error message.
404 or 477? There is huge difference!
Kamailio fails to send Invite message to user 1000. Is it possible that
kamailio is trying to forward INVITE packet to Contact Address rather then
the TCP connected which is already established between kamailio and
grandstream device.
Of course this will happen unless you use the add_contact_alias() and
handle_ruri_alias() functions as stated in my other email.
btw: Have you tested SIP over TCP? If TCP works, TLS will work too. IF
TCP does not work, TLS will also not work.

I am attaching the log file.
few things are like:

i have configure tls section in my kamailio like below:
disable_tls = no
listen = tls:172.16.16.218:5091
tls_verify_server = 1
tls_verify_client = 0
tls_require_client_certificate = 0
tls_method = TLSv1
tls_certificate =
"/data/hemanshu/install/kama/etc/kamailio/tls/user/user-cert.pem"
tls_private_key =
"/data/hemanshu/install/kama/etc/kamailio/tls/user/user-privkey.pem"
tls_ca_list =
"/data/hemanshu/install/kama/etc/kamailio/tls/user/user-calist.pem"
Please let me know if i am making any mistake in configuration or anything
else?
