siptrace: how to log sent ACK within dialog
by Seudin Kasumovic 17 Jun '15

17 Jun '15

Hi, TM forward ACK statelessly (see log below), so there is no call of installed callback on TMCB_REQUEST_(IN)SENT in siptrace module, so I can't see way how to log ACK sent packet. Any work around to get sent ACK logged? DEBUG: sl [sl_funcs.c:388]: sl_filter_ACK(): DEBUG : sl_filter_ACK: to late to be a local ACK! DEBUG: <script>: 408:172.16.23.130:5060 <-- 198.51.100.137:52150 ACK sip:8807@127.0.0.1:5080;transport=udp DEBUG: <script>: 425: start trace ACK DEBUG: siptrace [siptrace.c:1865]: pipport2su(): the port string is 52150 DEBUG: siptrace [siptrace.c:1865]: pipport2su(): the port string is 5060 DEBUG: siptrace [siptrace.c:1677]: trace_send_hep_duplicate(): setting up the socket_info DEBUG: <script>: 542: WITHINDLG: loose_route set du='sip:172.16.23.130:5070 ;lr;ftag=1029663405' DEBUG: <script>: 369: RELAY ACK sip:8807@127.0.0.1:5080;transport=udp [4194308] DEBUG: tm [t_lookup.c:1312]: t_newtran(): DEBUG: t_newtran: msg id=4 , global msg id=3 , T on entrance=0xffffffff DEBUG: tm [t_lookup.c:466]: t_lookup_request(): t_lookup_request: start searching: hash=34522, isACK=1 DEBUG: tm [t_lookup.c:424]: matching_3261(): DEBUG: *RFC3261 transaction matching failed* DEBUG: tm [t_lookup.c:648]: t_lookup_request(): DEBUG: t_lookup_request: no transaction found DEBUG: tm [t_funcs.c:279]: t_relay_to(): SER: forwarding ACK statelessly DEBUG: <script>: 821:172.16.23.130:5060 --> 172.16.23.130:5070 ACK sip:8807@127.0.0.1:5080;transport=udp Regards, Seudin Kasumovic

Getting 407 response when calling out (on bulk registration)
by Al S 17 Jun '15

http_query failed to perform curl (28) errors
by Armen Babikyan 17 Jun '15

17 Jun '15

Hello, I am running across the same issue as described here: http://lists.sip-router.org/pipermail/sr-users/2015-February/086796.html Was there a resolution to this issue? I come across this issue fairly regularly. Unlike the OP, however, I do not have any luck by retrying my query: when I place my http_query within a while loop and keep 1-second delays between calls, all consistently fail with error 28. After long pauses, http_query()s start to work as expected. I think that previous thread mentions DNS as a possible culprit. Is http_query using libcurl's preferred resolver, or is it using Kamailio's built-in DNS cache? I really doubt my local resolver is cause of the issue here. Any insight is appreciated. Thanks! Armen

Kamailio Crash
by Marc Soda 17 Jun '15

17 Jun '15

Is it normal for Kamailio to segfault on a duplicate key in the usrloc DB? Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Duplicate entry 'uloc-557a96c1-3577-4e5f1' for key 'ruid_idx' Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: <core> [db_query.c:337]: db_do_update(): error while submitting query Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: usrloc [ucontact.c:800]: db_update_ucontact_addr(): updating database failed Jun 15 18:15:23 vproxy2 /usr/sbin/kamailio[13646]: ERROR: usrloc [urecord.c:368]: wb_timer(): updating contact in db failed (aor: sip305_isibmp) I believe that there should never be a duplicate key. I'm not sure how that's happening either. I have 3 Kamailio boxes in a cluster replicating registrations to each other and using a MySQL Galara cluster for the usrloc DB. This is Kamailio 4.0.6. Thanks, Marc

loose_route to find transport=tcp
by Ryan Kendrick 16 Jun '15

16 Jun '15

We are using Kamailio 4.2.5 as a registrar and proxy between many dispersed end-users of a soft phone app and our calling platform / switch. Until now we have used udp exclusively but are trying to introduce tcp between end-users and Kamailio, leaving udp between Kam and our switch...while maintaining the ability for some end-users to use udp to Kam. With some simple address checks I am able to always send to our switch over udp. If all end-users used tcp I could send everything else tcp, but I need to maintain udp support. The specific problem I am having is on a reINVITE such as this one from our platform to the a-leg: INVITE sip:xxxxxx@xxxxxxxxxxxxx:42679;user=phone SIP/2.0 Via: SIP/2.0/UDP xxxxxxxxxxxxx:5060;branch=z9hG4bK218cc8e12ll5035f67INV6a67885312aad Max-Forwards: 35 Route: <sip:xxxxxxxxxxx;lr;r2=on;ftag=daba971c;did=b57.4872;nat=yes> Route: <sip:xxxxxxxxxxx:5070;transport=tcp;lr;r2=on;ftag=daba971c;did=b57.4872;nat=yes> Contact: <sip:xxxxxxxxxx@xxxxxxxxxxxxx:5060> To: "xxxxxx"<sip:xxxxxx@xxxxxxxxxxxxxxxxxxxxxxxxxxx:5070>;tag=daba971c From: <sip:xxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxxxxxxxx :5070>;tag=6a678853-co76461-INS002 Call-ID: MDI4ZmFjNmZhN2Y1NWE2ZTViNTkyZGUwNWE2YzUzYmU CSeq: 7646101 INVITE Allow: INVITE,ACK,CANCEL,BYE,REFER,OPTIONS,NOTIFY,SUBSCRIBE,PRACK,INFO,UPDATE Content-Type: application/sdp Date: Mon, 15 Jun 2015 20:10:18 GMT User-Agent: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Content-Length: 262 As you might notice, we have rr:enable_double_rr set: *There are some situations when the server needs to insert two Record-Route header fields instead of one. For example when using two disconnected networks or doing cross-protocol forwarding from UDP->TCP. This parameter enables inserting of 2 Record-Routes. The server will later remove both of them. * and I believe it is necessary to keep this way. Without it Kamailio doesn't even see the reINVITE...the switch probably tries tcp and that's not setup between the two. The invite above is sent to the a-leg over udp but I would expect and need it to be tcp in this case. The reINVITE is part of an existing dialog. We call loose_route() followed by some simple bflag setting and flag checking, t_on_reply(), ... then t_relay(). I do have a functional workaround but would prefer to avoid such manual handling by utilizing built-in functionality properly. # # relay the message # if(route(TEST_TOGW)) { if (!t_relay_to_udp()) { sl_reply_error(); } } else { if ($(hdr(Route)[-1]) =~ "tcp") { if(!t_relay_to_tcp()) { sl_reply_error(); } } else if (!t_relay()) { sl_reply_error(); } } I'm not 100% sure how reliable or fast this will be, but it does work so far in my simple tests. Is loose_route supposed to see and use the transport=tcp but isn't for some reason? It seems like the right thing to do to me. If not, is there anything else I can/should be doing in the tm and/or rr modules to make Kamailio realize it needs to send this message over TCP? If not in those two modules is there some recommended way perhaps via registrar or usrloc etc. to make Kamailio remember/store when a user is connected via TCP and be able to do a quick lookup before sending to them? Anything else I'm missing or not thinking of? Please let me know if I can further explain and rest assured any assistance will be much appreciated!!!

Keep-Alive in dialog "freeing a free fragment"
by Dirk Teurlings - SIGNET B.V. 16 Jun '15

16 Jun '15

Hi, (Kamailio 4.2.3) Working to get dialogs closed and cleaned up nicely I'm looking into the ka_interval and ka_timer parameter of the dialog module. The following is now happening. Scenario: 1. Call gets setup 2. Callee's internet connection drops 3. Call gets terminated (nicely) due to ka_timer/ka_interval 4. Log fills with "freeing a free fragment" after about 10 seconds Digging into this I saw that the dialog is being closed and cleaned properly in step 3. But it fails to remove/clean the timers used for the keep-alive. That's what triggers step 4, which in turn tries to clean the (or some of the) dialog space again. Is this expected behaviour when using the keep-alive options, or am I running into somekind of (known) bug? Thanks in advance for any help. -- Cheers, Dirk Teurlings

CANCEL request and subsequent 487 response to INVTE configuration problem
by Joao Alves 16 Jun '15

16 Jun '15

Hi, I'm creating a configuration is for a SIP <> HTTP gateway (performing protocol conversion) and thus all SIP messages and responses needs to be generated from the kamailio config file. I'm failing to create the case where the calling user abandons the session, and thus, following the reception of a CANCEL a 200 "OK" needs to be sent to this transaction and later the 487 "Request Terminated" to the SIP INVITE original session. On the traces I see: SIP INVITE (Cseq 1 INVITE) --> 100 Trying (Cseq 1 INVITE) <-- 180 Ringing (Cseq 1 INVITE) <-- SIP CANCEL (Cseq 1 CANCEL) --> 200 Ok (CSeq 1 CANCEL) <-- 487 Request Terminated (CSeq 1 CANCEL) Have then tried several options, trying to force the CSeq 1 INVITE but without success. t_reply_callid("$ci", "$cs", "487", " Request Terminated "); t_reply_callid("$ci", "$rm", "487", "Request Terminated"); t_reply_callid("$ci", "1", "487", "Request Terminated"); For instance, for the last I get the following log. 6(60226) exec: *** cfgtrace:request_route=[REQINIT] c=[/etc/kamailio/kamailio.cfg] l=705 a=28 n=t_reply_callid 6(60226) DEBUG: tm [t_lookup.c:1715]: t_lookup_callid(): created comparable call_id header field: >Call-ID: 76589ZTJmNTAwZDhlOTZiM2I3MjhhYzllNjgyOWVjZGZmMzk < 6(60226) DEBUG: tm [t_lookup.c:1719]: t_lookup_callid(): created comparable cseq header field: >CSeq: 1 INVITE< 6(60226) DEBUG: tm [t_lookup.c:1722]: t_lookup_callid(): just locked hash index 18668, looking for transactions there: 6(60226) DEBUG: tm [t_lookup.c:1749]: t_lookup_callid(): DEBUG: t_lookup_callid: transaction not found. 6(60226) DEBUG: tmx [tmx_mod.c:500]: t_reply_callid(): Lookup failed - no transaction Could you assist here?
