Custom info in Contact header
by Igor Olhovskiy 23 Nov '21

23 Nov '21

Hello! On REGISTER I have a Contact header like Contact: <sip:90002@192.168.0.26:48579;transport=TLS>;some_id=90002-21080 But on calling fix_nated_register() -> save(), param some_id is lost from info, so, on INVITE to this account, some_id not appears in RURI. Is this a bug or a feature and I do need to find some workaround? -- Best regards, Igor

Help with Async transaction responses
by Michael Friesen 19 Nov '21

19 Nov '21

Hello, I am attempting to perform some asynchronous lookup upon receiving an INVITE and then reply with a 3xx response with a modified From header. My workflow now is to create a transaction when receiving the INVITE, suspend the transaction, perform the asynchronous lookup, continue the transaction upon response, and then modify the From header and reply. The ONLY problem I am having is modifying the From header! How can I modify the From header in this scenario? function ksr_request_route() if KSR.is_INVITE() then if KSR.tm.t_newtran() then cache_transaction_info() KSR.tmx.t_suspend() --perform async loookup end end return 1 end --This function called on response from async lookup. Equivalent of ONREPLY_ROUTE function ksr_reply_route() --Finds the transaction_index and transaction_label from a cache KSR.tmx.t_continue(transaction_index, transaction_label, "redirect_transaction"); KSR.x.drop() return 1 end function redirect_transaction() KSR.pv.sets("$fU", "Jenny") --Doesn't actually modify the from username for 302 response! KSR.tm.t_reply(302, "Redirecting") return 1 end Thank you much! -Michael

+ character in send_reply causes truncation of reply message?
by Benoît Panizzon 18 Nov '21

18 Nov '21

Hi send_reply("403", "+411234567 transit disallowed"); Causes the reply to be truncated after the e164 number. send_reply("403", "Forbidden +411234567 transit disallowed"); Causes the reply to be truncated after 'Forbidden'. Is there a special meaning to the + character? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

corex send()
by Ross McKillop 12 Nov '21

12 Nov '21

Hi All, Is there an equivalent to corex's send_tcp (https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp <https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp>) for TLS? I have a bit of an odd edge case where I can't add Via headers etc, and send_udp and send_tcp allow me to achieve what I want, but it doesn't seem to have a means of doing the same with TLS? Essentially I want to transparently proxy what is received by Kamailio on one interface to a TLS connection e.g. A = (TCP) => Kamailio = (TLS) => Remote Host (A) in this instance is already setting a Via header of the Kamailio's external IP and transport tis. I appreciate this is a non-standard way of doing it, but (A) is a black box that I can't change, what I'm essentially trying to do is have Kamailio handle the TLS but essentially (A) thinks it's at the edge. I can make it work with send_tcp for a standard TCP connection, but if I use t_relay or even forward() to send onwards by TLS then Kamailio obviously adds its own headers as you'd expect. Ross

Kamailio dropping ACKs
by Emilio Panighetti 12 Nov '21

12 Nov '21

Working on a proof of concept with Kamailio 5.5.2 (Installed via kamailio-5.5.2-0.el8.centos.x86_64 RPM from rpm.kamailio.org). Also note that this is using the LUA interface Running a simple SIPp scenario without registration. Routing is set with in Lua: KSR.dbg("EP: ksr_route_relay Check for Base Route\n"); if KSR.is_INVITE() and KSR.siputils.has_totag() < 0 then KSR.dbg("EP: ksr_route_relay Base Route\n"); --KSR.sl.send_reply("503", "OLGX Debug"); KSR.setdsturi("sip:192.168.1.14:5060"); --KSR.pv.sets("$du", "sip:192.168.1.12:5062"); end The problem is that Kamailio is dropping the ACK to the 200 OK from the UAS. Wireshark shows that the UAS is retransmitting the 200 OK and the ACK is not being forwarded from the UAC to the UAS. Within the Lua config script: -- Handle requests within SIP dialogs function ksr_route_withindlg() if KSR.siputils.has_totag() < 0 then return 1; end KSR.dbg("EP: ksr_route_withindlg has to-tag, it is within a dialog\n"); -- sequential request within a dialog should -- take the path determined by record-routing if KSR.rr.loose_route() > 0 then ksr_route_dlguri(); if KSR.is_BYE() then KSR.setflag(FLT_ACC); -- do accounting ... KSR.setflag(FLT_ACCFAILED); -- ... even if the transaction fails elseif KSR.is_ACK() then -- ACK is forwarded statelessly KSR.dbg("EP: ksr_route_withindlg Forwarding ACK\n"); ksr_route_natmanage(); elseif KSR.is_NOTIFY() then -- Add Record-Route for in-dialog NOTIFY as per RFC 6665. KSR.rr.record_route(); end KSR.dbg("EP: ksr_route_withindlg loose route calling ksr_route_relay\n"); ksr_route_relay(); KSR.dbg("EP: ksr_route_withindlg exit\n"); KSR.x.exit(); end if KSR.is_ACK() then if KSR.tm.t_check_trans() > 0 then -- no loose-route, but stateful ACK; -- must be an ACK after a 487 -- or e.g. 404 from upstream server KSR.dbg("EP: ksr_route_withindlg is ACK calling ksr_route_relay\n"); ksr_route_relay(); KSR.dbg("EP: ksr_route_withindlg exit\n"); KSR.x.exit(); else -- ACK without matching transaction ... ignore and discard KSR.dbg("EP: ksr_route_withindlg Unknown ACK exit\n"); KSR.x.exit(); end end KSR.sl.sl_send_reply(404, "Not here"); KSR.dbg("EP: ksr_route_withindlg exit after 404\n"); KSR.x.exit(); end And logs for the ACK: Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/udp_server.c:493]: udp_rcv_loop(): received on udp socket: (106/100/385) [[ACK sip:service@192.168.1.15:5060 SIP/2.0 0D 0A Via: SIP/2.0/UDP 192.168.1.12:5060;branch=z9hG4bK-1091869]] Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_fline.c:249]: parse_first_line(): first line type 1 (request) flags 1 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:677]: parse_msg(): SIP Request: Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:679]: parse_msg(): method: <ACK> Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:681]: parse_msg(): uri: <sip:service@192.168.1.15:5060> Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:683]: parse_msg(): version: <SIP/2.0> Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_hname2.c:293]: parse_sip_header_name(): parsed header name [Via] type 1 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_via.c:1303]: parse_via_param(): Found param type 232, <branch> = <z9hG4bK-1091869-1-5>; state=16 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=5 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:555]: parse_headers(): Via found, flags=2 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:557]: parse_headers(): this is the first via Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_hname2.c:293]: parse_sip_header_name(): parsed header name [From] type 4 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_hname2.c:293]: parse_sip_header_name(): parsed header name [To] type 3 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_addr_spec.c:185]: parse_to_param(): add param: tag=4088926SIPpTag014 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_addr_spec.c:864]: parse_addr_spec(): end of header reached, state=29 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:173]: get_hdr_field(): <To> [63]; uri=[sip:service@192.168.1.15:5060] Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:176]: get_hdr_field(): to body (39)[service <sip:service@192.168.1.15:5060>], to tag (17)[4088926SIPpTag014] Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_hname2.c:293]: parse_sip_header_name(): parsed header name [Call-ID] type 6 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/parse_hname2.c:293]: parse_sip_header_name(): parsed header name [CSeq] type 5 Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/parser/msg_parser.c:154]: get_hdr_field(): cseq <CSeq>: <1> <ACK> Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: <core> [core/receive.c:387]: receive_msg(): --- received sip message - request - call-id: [1-1091869(a)192.168.1.12] - cseq: [1 ACK] Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: LUA {ACK}: <core> [core/receive.c:259]: ksr_evrt_pre_routing(): event route core:pre-routing not defined Nov 11 12:24:36 ol-vm1 /usr/sbin/kamailio[2414]: DEBUG: LUA {ACK}: <core> [core/receive.c:457]: receive_msg(): preparing to run routing scripts...

[ndb_redis] init_without_redis issue
by Denys Pozniak 11 Nov '21

11 Nov '21

Hello! In our architecture, Kamailio uses 2 local Redis servers to get routing information. We noticed that if at the start of Kamailio the first in the modparam list is a running Redis server (name=real), and the second in the list is not running (name=fake), then Kamailio will not even try to connect to the running one. # ----- redis server params ----- modparam("ndb_redis", "init_without_redis", 1) modparam("ndb_redis", "server", "name=real;addr=127.0.0.1;port=6379;db=1") modparam("ndb_redis", "server", "name=fake;addr=127.0.0.1;port=6479;db=2") But if the servers in the list above are reversed, then everything will work as it should. Looks the initialization order affects behavior. Syslog output: Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: ERROR: ndb_redis [redis_client.c:224]: redisc_init(): Failed to create REDIS returned an error: Connection refused Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: ERROR: ndb_redis [redis_client.c:259]: redisc_init(): error communicating with redis server [fake] (127.0.0.1:6479/2): Connection refused Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: WARNING: ndb_redis [redis_client.c:264]: redisc_init(): failed to initialize redis connections, but initializing module anyway.
