Hi folks,
Since upgrading vom Kamailio 1.5 to 3.1 I have a problem using
get_redirects from the uac_redirect module. It seems that there is a
problem with parsing the Contact header from the received 302.
This is my script excerpt:
if (t_check_status("3[0-9][0-9]")) {
get_redirects("*");
if (!t_relay()) {
xlog("L_ERR","t_relay failed\n");
}
}
Some 302 messages lead (as expected) to INVITEs send to targets in the
Contact header, for others t_relay fails.
A working example would be
Contact:<sip:+49406686...@192.168.0.1:5060;user=phone>;q=0.5,<sip:
+49406686...@192.168.0.2:5060;user=phone>;q=0.25
It fails on
Contact: sip:+49406686...@192.168.0.1:5060
The following log messages appear when calling get_redirects (and
failing t_relay):
kamailio[7372]: DEBUG: uac_redirect [rd_funcs.c:74]: resume branch=0

The Contact header that fails obviously has no parameters for the URI
and contact itself. As far as I understand the RFC 3261 BNF this is
valid.
yes, the contact is valid. Can you place an xlog like:
xlog("=== contact header: $T_rpl($ct)\n");
in failure route and see if the contact header body is printed? You need
tmx module loaded.
Cheers,
Daniel
The 302 response is by the way created by kamailio when using the LCR
module (like this)
if (!load_gws("1")) {... exit;}
if (!next_gw()) {... exit; }
sl_send_reply("302", "Not here");
Did I miss anything when upgrading or is this a problem with the parser?
Cheers,
Stefan
