Hi klaus, Suppose I can't access to NAPTR settings. I need to manage SIP URI, so , If I right understand, the only way to use TLS protocol in kamailio 1.5 is to append ";transport=tls" in R-URI before relay. In other words I need to rewrite R-URI:
$ru = $ru + ";transport=tls" ; # and the t_relay t_relay() ;
something like that?
Regards,
Daniel

Hi all, I'm using kamailio 1.5 with TLS module. I need to make ENUM query and get NAPTR record.
From NAPTR lookup, I'd like to relay my SIP Invite with tls protocol.
How can I tell Kamailio to use TLS protocol ( instead of udp) after NAPTR lookup ?
I've try to set :
dns_tls_pref=1 dns_udp_pref=2 dns_tcp_pref=3
in the general section of kamailio.cfg, but I get a parse error.
these parameters were introduced in kamailio with version 3.0.
If you need TLS then it is recommended to use 3.0 anyhow, it is a far better implementation. That will make the life easier to migrate to upcoming 3.1 that will bring asynchronous TLS.
No matter what you have in R-URI, you can force TLS via setting outbound proxy address to be a TLS uri:
$du = "sip:__ip_or_host__;transport=tls"; t_relay();
IIRC we do have NAPTR support in Kamailio 1.5 - don't we?
Then I think it should work when putting a domain into $du and makeing sure that there is no transport parameter, no port, and NAPTR TLS record has highest priority.
regards klaus
The IP or host you can take from R-URI without any problem via PV $rd. Other option is to use function from tm - t_relay_to_tls():
