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:+49406686100@192.168.0.1:5060;user=phone;q=0.5,sip: +49406686100@192.168.0.2:5060;user=phone;q=0.25
It fails on Contact: sip:+49406686100@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 (added=0) kamailio[7372]: DEBUG: uac_redirect [rd_funcs.c:85]: branch=0 is a redirect (added=0) kamailio[7372]: WARNING:<core> [mem/q_malloc.c:366]: qm_malloc(0x82ba320, 32) called from<core>: parser/msg_parser.c: parse_headers(339) kamailio[7372]: WARNING:<core> [mem/q_malloc.c:406]: qm_malloc(0x82ba320, 32) returns address 0x8311d94 frag. 0x8311d7c (size=32) on 1 -th hit 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.
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?
