restore_uri_reply() called twice in 200OK to BYE

by Efelin Novak

Hi Folks, I have a problem with To and From headers in 200 OK to BYE request. Their URI is doubled when leaving Kamailio. Incoming 200 OK: From : <sip:00421111@IP_ADDRESS>;tag=as017a2986 To : <sip:00421222@IP_ADDRESS0>;tag=K7ryDgH2g7gFm Outgoing 200 OK: From : <sip:+421111@IP_ADDRESS><sip:+421111@IP_ADDRESS>;tag=as017a2986 To : <sip:+421222@IP_ADDRESS><sip:+421222@IP_ADDRESS>;tag=K7ryDgH2g7gFm I'm using uac module to replace these headers in auto and dialog mode: modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) append_fromtag is also set: modparam("rr", "append_fromtag", 1) When I run kamailio in debug mode I can see the function restore_uri_reply() is called twice: . . . 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 234, <received> = <IP_ADDRESS>; state=6 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 232, <branch> = <z9hG4bK0bb8c5b2>; state=6 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 235, <rport> = <5060>; state=16 0(3133) DEBUG: <core> [parser/parse_via.c:2672]: parse_via(): end of header reached, state=5 0(3133) DEBUG: <core> [parser/msg_parser.c:513]: parse_headers(): parse_headers: Via found, flags=62 0(3133) DEBUG: <core> [parser/msg_parser.c:526]: parse_headers(): parse_headers: this is the second via 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:176]: parse_to_param(): DEBUG: add_param: tag=teHD72X67aQUm 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:898]: parse_addr_spec(): end of header reached, state=29 0(3133) DEBUG: <core> [parser/msg_parser.c:190]: get_hdr_field(): DEBUG: get_hdr_field: <To> [60]; uri=[sip:421222@IP_ADDRESS:5060] 0(3133) DEBUG: <core> [parser/msg_parser.c:192]: get_hdr_field(): DEBUG: to body [<sip:421222@IP_ADDRESS:5060>] 0(3133) DEBUG: <core> [parser/msg_parser.c:170]: get_hdr_field(): get_hdr_field: cseq <CSeq>: <103> <BYE> 0(3133) DEBUG: tm [t_lookup.c:949]: t_reply_matching(): DEBUG: t_reply_matching: hash 10806 label 0 branch 0 0(3133) DEBUG: tm [t_lookup.c:1004]: t_reply_matching(): DEBUG: t_reply_matching: reply matched (T=0x220071b4)! 0(3133) DEBUG: tm [t_hooks.c:288]: run_trans_callbacks_internal(): DBG: trans=0x220071b4, callback type 2, id 0 entered 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:176]: parse_to_param(): DEBUG: add_param: tag=as46bccb83 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:898]: parse_addr_spec(): end of header reached, state=29 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421222@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421222@IP_ADDRESS>> 0(3133) DEBUG: tm [t_hooks.c:288]: run_trans_callbacks_internal(): DBG: trans=0x220071b4, callback type 2, id 0 entered 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421222@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421222@IP_ADDRESS>> . . . I think the problem is in registering a function restore_uris_reply() in callbacks in functions (both in replace.c of uac module) * void rr_checker(struct sip_msg *msg, str *r_param, void *cb_param) * static void replace_callback(struct dlg_cell *dlg, int type, struct dlg_cb_params *_params) Both of these callbacks are registered for BYE and ACK requests (INVITE request is using different callback), therefore running restore_uri_reply() twice. For testing purposes after I have removed the callback in rr_checker and recompile the uac module, To and From headers were OK. In my configuration I'm calling uac_replace_to in RELAY route: route[RELAY] { if ( !has_totag() ) { dlg_manage(); uac_replace_to("$ru"); } if (!t_relay()) { sl_reply_error(); } } So I think there is a bug in uac module, when one function is registered twice in callbacks for NON-INVITE requests. Or is there a problem with my configuration script? Can anyone point me to the direction how to solve this issue? Thank you Efelin Kamailio version: kamailio 4.4.0-dev6 (i386/linux) a66e22-dirty

Kamailio as UAC

by Alexandru Covalschi

Hello everyone! Subj is an ethernal theme, I know, but odds are so that I just need to do that. I've configured UAC auth to successfully register and my route[PSTN] looks like that # check if PSTN GW IP is defined if (strempty($sel(cfg_get.pstn.gw_ip))) { xlog("SCRIPT: PSTN routing enabled but pstn.gw_ip not defined\n"); return; } if !ds_is_from_list() return; # route to PSTN dialed numbers starting with '+' or '00' # (international format) # - update the condition to match your dialing rules for PSTN routing if(!($rU=~"^(\+|00)[1-9][0-9]{3,20}$")) return; if (strempty($sel(cfg_get.pstn.gw_port))) { $ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip); } else { $ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip) + ":" + $sel(cfg_get.pstn.gw_port); } remove_hf("To"); insert_hf("To: <sip:$rU@sipprovider.com>\r\n", "Call-ID"); uac_replace_from("","sip:user@sipprovider.com"); route(RELAY); exit; On INVITE's I get 407 PROXY-AUTH, which are transfered to backend FS. If I try to put if ($T_reply_code == 401 or $T_reply_code == 407) { xlog("L_NOTICE", "Remote asked for authentication"); uac_auth(); } to MANAGE_FAILURE or MANAGE_REPLY route Kamailio can't start. Is that even possible? -- Alexandru Covalschi ABRISS-Solutions VoIP engineer and system administrator phone: +37367398493 web: http://abs-telecom.com/

how to log sql query

by John Smolka

Hi guys, I use kamailio with mysql. Some queries are huge and when I need to debug something it takes a time, so the debbuging would be easier. Is there any way how could I log all sql queries into a log file ? Thanks, John

Media address family

by Sergey Okhapkin

What is the best way to find out address family (IPV4 or IPV6) of media in SDP? My goal is to reject INVITEs which have different address families in headers and SDP, i.e. IPv4 INVITE with IPv6 media address in SDP and vice versa.

2 Kamailio servers on same domain

by Michael Nielsen

I've installed Kamailio on 2 different servers. They share the same PostgreSQL database for users etc. I've setup a single domain, sip.my-domain.com, with latency responds to the 2 servers. So a user will always land on the server with the fastest responds in a respective area of the world. However, it seems as if 2 users are registered on different Kamailio servers - even though they share the same database - they cannot call each other? Have I misunderstood something? I've enabled WITH_NAT.

kamailio very slow or stuck during period from time to time

by Thibault Gueslin

I am facing an issue with kamailio 4.3.3 that is very similar to http://lists.sip-router.org/pipermail/sr-users/2015-May/088195.html Had someone found the solution or faced similar issue ? Sometimes kamailio is receiving the message (check with wireshark, logs in tcp) but the message is not handled nor relayed. After a certain amount of time everything works fine. I will do what as has been advised : enabling pike & check with gdb when it appears. thibault

[CFP] reminder! FOSDEM RTC dev-room talks: deadline Friday

by Daniel Pocock

Reminder: speaker's deadline this Friday, 27 November at 23:59 UTC We have already received several really exciting talk proposals but there is still time for people to propose talks or encourage friends or colleagues to speak. Many other dev-rooms also have a deadline in the next few days and if your topic is applicable to more than one dev-room, you are welcome to make more than one submission. Please contact us or put a note in the memo field at the top of the talk proposal if you do that. All projects are encouraged to consider making a lightning talk too, it is an excellent opportunity to get exposure for your project: even though you only have 15 minutes, it can be a much larger and more diverse audience than in some dev-rooms. For full details, please see the call for papers: http://danielpocock.com/fosdem-2016-free-rtc-dev-room-and-lounge We invite all potential speakers and participants to discuss the selection process and other aspects of FOSDEM on the Free-RTC mailing list: https://lists.fsfe.org/mailman/listinfo/free-rtc
