Evapi module is not broadcasting any data
by Efelin Novak 22 Aug '16

22 Aug '16

Hi folks, I came into a problem with evapi module, while I was trying to make the CGRateS tutorial work. It does not send any messages at all. Taken steps: I start kamailio with debug=3. I start: CGRates (on the kamailio machine) telnet 192.168.30.29 8448 (from my PC) tcpdump port 8448 -A -s0 -i any (on the kamailio machine) Telnet command successfully connects to kamailio. Kamailio yells: root@cgrates:/opt/kamailio/src/kamailio-4.4/kamailio# 11(12205) DEBUG: evapi [evapi_dispatch.c:453]: evapi_accept_client(): new connection - pos[1] from: [192.168.30.1:40312] 11(12205) INFO: <script>: Starting Evapi connector srcaddr 192.168.30.1 srcport 40312 condix 1 11(12205) DEBUG: htable [ht_var.c:90]: pv_set_ht_cell(): set value for $sht(cgrconn=>cgr) A similar message is printed when CGRateS connects in. Afterwards I make a call to Kamailio. INVITE is routed to a following command: evapi_async_relay("{\"event\":\"CGR_AUTH_REQUEST\", \"tr_index\":\"$T(id_index)\", \"tr_label\":\"$T(id_label)\", \"cgr_reqtype\":\"$dlg_var(cgrReqType)\", \"cgr_tenant\":\"$dlg_var(cgrTenant)\", \"cgr_account\":\"$dlg_var(cgrAccount)\", \"cgr_destination\":\"$dlg_var(cgrDestination)\", \"cgr_setuptime\":\"$TS\", \"cgr_computelcr\":\"true\"}"); Now the kamailio writes: . . . 2(12196) DEBUG: dialog [dlg_var.c:260]: print_lists(): Dialog var-list (0x7f196d1c5248): 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrDestination=1002 (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrAccount=1001 (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrTenant= cgrates.org (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrReqType=*prepaid (flags 1) 2(12196) DEBUG: dialog [dlg_hash.c:922]: dlg_unref(): unref dlg 0x7f196d1c4c08 with 1 -> 1 2(12196) DEBUG: evapi [evapi_dispatch.c:603]: evapi_relay(): relaying event data [{"event":"CGR_AUTH_REQUEST", "tr_index":"59559", "tr_label":"1886589610", "cgr_reqtype":"*prepaid", "cgr_tenant":"cgrates.org", "cgr_account":"1001", "cgr_destination":"1002", "cgr_setuptime":"1471623526", "cgr_computelcr":"true"}] (246) 2(12196) DEBUG: evapi [evapi_dispatch.c:628]: evapi_relay(): sending [0x7f196d1c88b8] [246:{"event":"CGR_AUTH_REQUEST", "tr_index":"59559", "tr_label":"1886589610", "cgr_reqtype":"*prepaid", "cgr_tenant":"cgrates.org", "cgr_account":"1001", "cgr_destination":"1002", "cgr_setuptime":"1471623526", "cgr_computelcr":"true"},] (251) 2(12196) DEBUG: evapi [evapi_dispatch.c:630]: evapi_relay(): Len of write is 8 2(12196) INFO: <script>: suspended transaction: 59559 / 1886589610 . . .

Contact header / bye
by Oliver Roth 19 Aug '16

19 Aug '16

Hi all I do have a problem with getting a propper interconnection to our new carrier.. Situation as following User --> Class5 switch --> Kamailio --> carrier I always get the ip of the class5 switch in the contact. But my carrier needs the kamailios contact ip - because of the ack handling. I replaced in the pstn routing parte the contact by remove_hf("Contact"); append_hf("Contact: <sip:xyz@a.b.c.d>\r\n"); This worked - but the bye did not work any more. Please help me on that topic ... I am searching for a solution for more than 8 weeks now ... KR, Oli

Running both 4.3 and 4.4 with the same database with permission module
by Daniel Tryba 19 Aug '16

19 Aug '16

I want to upgrade my cluster from 4.3 to 4.4, beginning with the spare for live testing. But since there is a change to the trusted table (which we don't use, only address) this isn't possible without some tricks. There is no override for skipping the version check on any permissions table. I need to share the subscriber/location/address/usr_preferences and db_aliases tables between the 4.3 and 4.4 machines. The only thing I can think of is: -patch the permissions module to accept the old version of trusted -create a 4.4 database and use federated tables to access the 4.3 data Not hard to implement any of these 2, but some other modules have the option to skip these checks, eg: http://www.kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.p.v… Is there a reason not all modules have this flag (which you could use at your own risk)? Or am I missing something here?

Trouble with nat_uac_test()
by Noah Mehl 18 Aug '16

18 Aug '16

Hey all, I have a Kamailio implementation (version: kamailio 4.4.1 (x86_64/solaris) 12b048) as part of the Kazoo platform. I’m having an odd problem with an e2e ACK (after a 200OK after a T38 re-invite), which I’m pretty sure has to do with a Contact header rewrite due to the following (can review attached PCAP for specifics): if (nat_uac_test("3")) { force_rport(); fix_nated_contact(); } I have a couple of questions about this: A flag of 3, I don’t understand. I read the documentation <http://kamailio.org/docs/modules/4.4.x/modules/nathelper.html#nathelper.f.n…>, and there is a 1,2,4,8,etc… So, I’m guessing that a flag of 3, means 1+2? If #1 is true, then "the "received" test is used: address in the “Via” header is compared against source IP address of signaling” I don’t understand this test, as I’m pretty sure that the 200OK that’s getting re-written is properly constructed. I guess I’m trying to understand when one would want to use this test? Thanks! ~Noah

msilo route error
by Eng Hooda 18 Aug '16

18 Aug '16

Hello All, I am trying to enable msilo offline message delivery module, I used the official technical documentation : https://www.kamailio.org/docs/modules/stable/modules/msilo.html I managed to add load module statement and modparam statement without error. At this point msilo is still not active , it was obvious that I needed to add route statement. I copied the provided route statement , and edited it so will be similar to route functions that are already there. that was the outcome: # Routing to MSILO route[MSILO] { #!ifdef WITH_MSILO if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); exit; }; if (uri==myself) { { # for testing purposes, simply okay all REGISTERs if (method=="REGISTER") { save("location"); log("REGISTER received -> dumping messages with MSILO\n"); # MSILO - dumping user's offline messages if (m_dump()) { log("MSILO: offline messages dumped - if they were\n"); }else{ log("MSILO: no offline messages dumped\n"); }; exit; }; # domestic SIP destinations are handled using our USRLOC DB if(!lookup("location")) { if (! t_newtran()) { sl_reply_error(); exit; }; # we do not care about anything else but MESSAGEs if (!method=="MESSAGE") { if (!t_reply("404", "Not found")) { sl_reply_error(); }; exit; }; log("MESSAGE received -> storing using MSILO\n"); # MSILO - storing as offline message if (m_store("$ru")) { log("MSILO: offline message stored\n"); if (!t_reply("202", "Accepted")) { sl_reply_error(); }; }else{ log("MSILO: offline message NOT stored\n"); if (!t_reply("503", "Service Unavailable")) { sl_reply_error(); }; }; exit; }; # if the downstream UA does not support MESSAGE requests # go to failure_route[1] t_on_failure("1"); t_relay(); exit; }; # forward anything else t_relay(); } failure_route[1] { # forwarding failed -- check if the request was a MESSAGE if (!method=="MESSAGE") { exit; }; log(1,"MSILO:the downstream UA doesn't support MESSAGEs\n"); # we have changed the R-URI with the contact address, ignore it now if (m_store("$ou")) { log("MSILO: offline message stored\n"); t_reply("202", "Accepted"); }else{ log("MSILO: offline message NOT stored\n"); t_reply("503", "Service Unavailable"); }; } #!endif return; } but after that I restarted kamailio service and got the following errors: root@debian:~# service kamailio restart Job for kamailio.service failed.

t_set_fr() different behavior whether transport is udp or tcp
by Daniel Tryba 16 Aug '16

16 Aug '16

I'm seeing a different behavior of t_set_fr depending on transports. Scenario is that a endpoint has a failover defined in the registrat after 10s (t_set_fr(10000) and handling the locally generated 408 to the failover destination). This works fine when the request and response where delivered over UDP. When the Path is TCP the failover happends after 30s (even when using a different time t_set_fr(20000) so it is not a factor 3 or something like that). Setup: OK, 10s: Orig->UDP->loadbalancer->UDP->registrar->UDP->loadbalancer->TCP->Term Fail, 30s: Orig->UDP->loadbalancer->TCP->registrar->TCP->loadbalancer->TCP->Term Loadbalancer and registrar are kamailio machines (4.3.6). Communication between lb and registrar is based on dispatcher and path modules. 1 sip:registrar:5060;transport=udp 8 0 or via tcp: 1 sip:registrar:5060;transport=tcp 8 0 In the location database of the registrar the difference between the cases is: socket: udp:registrar:5060 or via tcp tcp:registrar:5060 path: <sip:lb@loadbalancer;lr;received=sip:1.2.3.4:5067%3Btransport%3Dtcp> or via tcp <sip:lb@loadbalancer;transport=tcp;lr;received=sip:1.2.3.4:5067%3Btransport%3Dtcp> Looking at debug(=3) nothing happens between the initial INVITE and the local 408 as far as I can see.

302 - stop sending once ACKed

Is ACK required in a re-invite?
by Jay Li 15 Aug '16

15 Aug '16

Dear All, I just have a basic SIP question on re-invite. I wonder if "ACK" is required in a re-invite scenario, like re-invite -> 200 OK -> ACK. What I've seen is for some reason, my PSTN doesn't send a "ACK" back to me after my 200 OK response to their re-invite. I don't know if not sending an ACK in a re-invite is an allowed behavior. Thanks. Regards,Jay

Via in locally generated PUBLISH (using different presence server address)
by Asgaroth 15 Aug '16

15 Aug '16

Hi All, I have a configuration where we run a multi-homed proxy/loadbalancer and a seperate internal presence server. We then use pua/pua-dialoginfo on the proxies to publish dialog state to the internal presence server. The proxies listen on udp:external_ip:5062 and udp:internal_ip1:5060. The presence server listens on udp:internal_ip2:5060 on a seperate server. The problem I am coming accross is that when kamailio generates a PUBLISH message for some dialogs it creates the via header with address external:ip:5062, however the pua module is configured to send to the presence server address on internal_ip2:5060. I have a route which forces the sending socket ($fs) to be udp:internal_ip1:5060. What happens then is that the presence server tries to send the 200 reply to the PUBLISH message back to internal_ip1:5062 (when it should be internal_ip1:5060), I'm thinking this is because the Via header has host as external_ip:5062. Is it possible, from event-route[tm:local-request] to rewrite the via header so that it reflects internal_ip1:5060 instead of external_ip:5062? I did try the following snippet from event-route[tm:local-request], but I got module parse errors on the Via header: if (is_method("PUBLISH")) { subst_hf("Via", "/ 1\.2\.3\.[0-9]+:5062;/ $sel(cfg_get.socket.internal_ip);/", "f"); } [7370]: ERROR: <core> [parser/parse_via.c:2607]: parse_via(): ERROR:parse_via on <1> state 5 (default) [7370]: ERROR: <core> [parser/parse_via.c:2708]: parse_via(): ERROR: parse_via on: <SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 internal_ip1; [7370]: ERROR: <core> [parser/parse_via.c:2712]: parse_via(): ERROR: parse_via parse error, parsed so far:<SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 > [7370]: ERROR: <core> [parser/msg_parser.c:125]: get_hdr_field(): ERROR: get_hdr_field: bad via [7370]: INFO: <core> [parser/msg_parser.c:338]: parse_headers(): ERROR: bad header field [Via: SIP/2.0/UDP 1] [7370]: ERROR: <core> [parser/msg_parser.c:690]: parse_msg(): ERROR: parse_msg: message=<PUBLISH sip:user@domain;transport=UDP SIP/2.0#015#012Via: SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 internal_ip1;To: <sip:user@domain;transport=UDP>#015#012From: <sip:user@domain;transport=UDP>;tag=3e8fdaca277026bf3e6d75c5e5313096-f162#015#012CSeq: 10 PUBLISH#015#012Call-ID: 5634294b786134b3-7370@external_ip#015#012Content-Length: 692#015#012User-Agent: kamailio (bfievklb04)#015#012Max-Forwards: 70#015#012Event: dialog#015#012Expires: 10901#015#012Content-Type: application/dialog-info+xml#015#012#015#012<?xml version="1.0"?>#012<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:user@domain;transport=UDP">#012 <dialog id="mvqXXaAr24DHdfsffYKZeA.." call-id="mvqXXaAr24DHdfsffYKZeA.." direction="initiator">#012 <state>Trying</state>#012 <remote>#012 <identity>sip:1234567@domain;transport=UDP</identity>#012 <target uri="sip:1234567@domain;transport=UDP"/>#012 </remote>#012 <local>#012 <identity>sip:user@domain;transport=UDP</identity>#012 <target uri="sip:user@domain;transport=UDP"/>#012 </local>#012 </dialog>#012</dialog-info>#012> [7370]: ERROR: <core> [msg_translator.c:3057]: build_sip_msg_from_buf(): parsing failed [7370]: ERROR: tm [uac.c:163]: uac_refresh_hdr_shortcuts(): failed to parse msg buffer [7370]: ERROR: tm [uac.c:487]: t_uac_prepare(): failed to refresh header shortcuts [7370]: ERROR: pua [send_publish.c:700]: send_publish(): in t_request tm module function [7370]: ERROR: pua_dialoginfo [dialog_publish.c:358]: dialog_publish(): while sending publish To me, it looks like the replace section of the subst_hf sub expression is being appended to the end of the via header instead of replacing the address section found.

Kamailio 4.4 Dispatcher on Debian 8 with MongoDB
by Jonathan Hunter 12 Aug '16

Hi Guys, I am integrating kamailio with MongoDB, and it works well with subscriber/location tables. However when using the dispatcher module I am getting the following error even though the IP Im trying to get to is routeable; /usr/local/kamailio-4.4/sbin/kamailio[2998]: ERROR: dispatcher [dispatch.c:1403]: ds_get_index(): destination set [1] not foundAug 11 17:01:47 ip-172-31-43-8 /usr/local/kamailio-4.4/sbin/kamailio[2998]: ERROR: dispatcher [dispatch.c:1832]: ds_select_dst_limit(): destination set [1] not found I created the table as below; db.getCollection("version").insert({table_name: "dispatcher", table_version: NumberInt(4) }) And the entry Im routing to is; db.dispatcher.find().pretty(){ "_id" : ObjectId("57acadc81e7e803fa565bce3"), "setid" : "1", "destination" : "sip:1.1.1.1:5080;transport=tcp", "flags" : "0", "priority" : "100", "attrs" : "name=labfS", "description" : "FreeSWITCH1"} Is there something I am missing ? Has anyone else got it working with Mongo? Thanks Jon

Re: [SR-Users] kamailio starts looping invites(some) back to itself.
by SamyGo 10 Aug '16

10 Aug '16

Hi Aqs, How about putting a loop protection of some sort additionally like $si != myself. Is there any chance the API http call is getting skipped to relay w/o getting any reply back and hence looping back to itself ? Regards, Sammy On Jul 22, 2016 14:17, "Aqs Younas" <aqsyounas(a)gmail.com> wrote: Hi, I am using http_async_client and dispatcher modules of Kamailio. Here is scenario! http_async_client makes calls to an API to get groupid upon which dispatcher sends calls. I am using SIPp to generate calls with 100 cps. I see some calls being failed with an error cause, 483 Too Many Hops. Taking the trace shows Kamailio routing some calls to itself. I think this is not a configuration issue since all calls are same(follow same logic) and some calls get failed. Any pointer is much appreciated.

Problem receiving large payloads from JSONRPC-S

Hi, I'm requesting 'dlg.list' from JSONRPC-S via XHTTP on a rather busy server, i.e. event_route[xhttp:request] { xlog("L_INFO", 'action=ER-XHTTP-REQUEST | ret=LOG_HTTP_REQ | data={"method": "$rm", "path": "$hu", "source": "$si:$sp"}'); # Digest challenge omitted. if($hu =~ "^/rpc") { xlog("L_INFO", 'action=ER-XHTTP-REQUEST | ret=JSON_RPC_REQUEST | data={"path": "$hu"}'); jsonrpc_dispatch(); } else { xhttp_reply("404", "Not Found", "text/html", ""); } } # curl --digest -v \ -X POST -H 'Content-Type: application/json' \ -H 'Call-ID: abc12' \ -d '{"jsonrpc": "2.0", "method": "dlg.list", "id": "0deadb33f"}' \ 'http://sipus_adm:raSheinmet4@10.0.62.74:5060/csrp_rpc/' and finding that when there's more than a hundred or so dialogs in play, Kamailio abruptly closes the connection in the middle of returning the output: ----- "tag": "AF5DA9B4-6D5", "contact": "sip:14045551212@xxx.xxx.xxx.xxx:5060", "cseq": "0", "route_set": "", "socket": "udp:xxx.xxx.xxx.xxx:5060" }, * transfer closed with 151674 bytes remaining to read * Closing connection #0 curl: (18) transfer closed with 151674 bytes remaining to read "profiles": ["total",[root@proxy kamailio]# ------ I can't seem to figure out what parameters regulate this.
