302 - stop sending once ACKed
by jaflong jaflong 16 Aug '16

16 Aug '16

I have kamailio as a redirect server. It responds with 302 to invites. The problem I am having is it continues to send the 302 multiple times. How can i get it to stop sending once it gets the first ACK

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. I have sanitized the above output to not show internal details, but if you need it, I can send it on to you privately. Am I going about this issue in the correct way, and, if so, where am I going wrong with the subst_hf snippet above? Kamailio version is 4.3.6. Any pointers/tips/trciks are greatly appreciated. Thanks

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

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
