Dialog module event_route problem
by betul.cerit＠netgsm.com.tr 13 Aug '14

Hello; I am trying to build a prepaid accounting system. I use dialog module's start/end event-route. When even_route[dialog:started] triggered, a http_query works for the started call. When event_route[dialog:end] triggered , a http_query works for call is ended. When http_query works in event_route[dialog:started], i get some CRITICAL ERROR like 'Aug 12 12:16:09 /usr/local/sbin/kamailio[10151]: CRITICAL: dialog [dlg_timer.c:205]: update_dlg_timer(): Trying to update a bogus dlg tl=0x7f7634d925d8 tl->next=(nil) tl->prev=(nil)' 'Aug 12 12:16:09 /usr/local/sbin/kamailio[10151]: ERROR: dialog [dlg_handlers.c:1263]: dlg_onroute(): failed to update dialog lifetime' Http_query works very well. I can get all call information on Web Servers but default_time out or other timeout isn't working. After i commented out http_query in event_route[dialog:started] , it stopped giving ERROR but i realized that dialog cannot uptade dialog hash map .I can see all finished call with "kamctl dialog show". After i closed http_query in even_route[dialog:end] , all problems are solved. I think a problem occured between http_query and dialog event_routes.It cannot control dialog lifetime.Any idea about this problem or suggest an alternative way will be appreciated.My configuration is as follows.

Call disconnects within 30 seconds
by Rahul MathuR 13 Aug '14

13 Aug '14

Hello, I have an iPhone/Android/Windows 8 based UAC, proxy server Kamailio and Sip server FreeSwitch. Whenever I call directly from UAC to Sip server, the call gets established for as long as I want, however when I use the proxy in between, it gets disconnected within 30 seconds. It seems that FS sends a BYE within 30 seconds. I would really appreciate if anybody please guide me where I am going wrong in this case ? -- Warm Regds. MathuRahul

SDP ending with CRLF and a=nortpproxy:yes
by Narsay, Deep 12 Aug '14

12 Aug '14

Hello, Please let me know if there is any work around for this. Details of the issue: kamailio.cfg has this sequence in kamailio.cfg, ...... modparam("rtpproxy", "ice_candidate_priority_avp", "$avp(ice_priority)" ) ........ sdp_remove_line_by_prefix("a=candidate"); set_iattr("ice_priority", "1"); rtpproxy_manage("frwie"); I'm seeing an issue towards the bottom of the SDP message. .... a=ssrc:738345272 mslabel:VPELrlXvdfGmtevlYLEeVm6zq4JHvI4g a=ssrc:738345272 label:VPELrlXvdfGmtevlYLEeVm6zq4JHvI4ga0 a=ice-ufrag:YJuJWr9clIJHhENw a=ice-pwd:3v1D1ShCg8xIlDZ9 a=candidate:1297581420 1 udp 659136 10.1.2.3 17534 typ host generation 0 a=candidate:1297581420 2 udp 659136 10.1.2.3 17535 typ host generation 0 a=ptime:20 \r\n a=nortpproxy:yes\r\n The call gets rejected by UA due to an invalid (empty) line in SDP. Very old but somewhat similar issue: http://lists.sip-router.org/pipermail/users/2008-September/019605.html (Module authors, I'll be happy to code/test or assist in any way possible if needed.) Just to test it, I commented the following code snippet and the call worked. But that can't be the permanent fix. Thank you, - Deep N Code snippet:rtp_proxy.c::force_rtp_proxy starting from line 2850 * if (proxied == 0 && nortpproxy_str.len) { cp = pkg_malloc((nortpproxy_str.len + CRLF_LEN) * sizeof(char)); if (cp == NULL) { LM_ERR("out of pkg memory\n"); return -1; } anchor = anchor_lump(msg, body.s + body.len - msg->buf, 0, 0); if (anchor == NULL) { LM_ERR("anchor_lump failed\n"); pkg_free(cp); return -1; } memcpy(cp, CRLF, CRLF_LEN); memcpy(cp + CRLF_LEN, nortpproxy_str.s, nortpproxy_str.len); if (insert_new_lump_after(anchor, cp, nortpproxy_str.len + CRLF_LEN, 0) == NULL) { LM_ERR("insert_new_lump_after failed\n"); pkg_free(cp); return -1; } }*

Routing for case of client's changing networks
by Dmytro Bogovych 11 Aug '14

11 Aug '14

Greetings all. I have following use case: 0) Peer A and B registers on kamailio via TLS. 1) Peer A establishes call to peer B. 2) Peer A changes network and call has to be refreshed. Peer A reregisters, gathers ICE candidates, builds reINVITE and sends it to B. After peer A changes network again, reregisters and waits for answer from old reINVITE. 3) Peer B receives reINVITE and sends answer. The problem is this answer never gets to peer B. Kamailio cannot route answer as old TLS connection is closed and new one did not established before reregistering. Is there way to solve or avoid this situation? Thank you :)

http_query results question
by Jonathan Hunter 11 Aug '14

11 Aug '14

Hi Guys, I have used the http_query function in the past, in conjunction with the json module, on version 3.3 and unbuntu. I am now using version 4.1 on Centos 6.5, and I am using the http_query, which I'm aware records in the results the first line of the response. Can you select the result to be recorded depending on the line in the response, for example if a number is returned only in line 4, can this be extracted from a 200 ok response using this function? Or is this then a need to use JSON module, and if so which repository for centos 6.5 contains it! :) Sorry for the question! Thanks Jon

Dispatcher caches IP
by Yuriy Gorlichenko 11 Aug '14

Hello. I try to integrate dispathcer module (with db table dispatcher) to my Kamailio server. I have problem with changing IP at db table, but when I calling - call goes to old IP that alread deleted from db. I tested my table with query that selects destination address from table, and it replyes to me correct address. I use round-robin ("4") algorythm modparam("dispatcher", "db_url",DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "setid_col", "setid") modparam("dispatcher", "destination_col", "destination") modparam("dispatcher", "force_dst", 1) modparam("dispatcher", "flags", 3) modparam("dispatcher", "dst_avp", "$avp(i:271)") modparam("dispatcher", "grp_avp", "$avp(i:272)") modparam("dispatcher", "cnt_avp", "$avp(i:273)") modparam("dispatcher", "ds_ping_from", "sip:proxy@10.0.0.2") modparam("dispatcher", "ds_ping_interval",15) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=404;code=484;class=3") How to disable this cache?

Accessing Message Buffer in Kamailio
by AliReza Khoshgoftar Monfared 08 Aug '14

08 Aug '14

Hi list, Is there a way to survey the message buffer (iei the queue where arriving sip messages wait to be processed by worker threads) in Kamailio? Is there a way to check the number of messages in this buffer? Additionally, is it possible to survey the number of messages by method (INVITE, BYE, etc.)? I know that the ratelimit module ( http://kamailio.org/docs/modules/stable/modules/ratelimit.html) shall access such buffers, but I do not see any variable accessible in the config offered by that module. Am I missing sth or is there a way to do so? Thanks Alireza
