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
kamailio[7372]: DEBUG: uac_redirect [rd_funcs.c:81]: checking branch=0

kamailio[7372]: DEBUG: uac_redirect [rd_funcs.c:233]: contact hdr not
found in sh_rpl
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.
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
