Dispatcher Routing Failure
by Daniel W. Graham 27 Mar '18

27 Mar '18

What constitutes a 'failed request' in dispatcher module, in which a gateway is marked inactive? >From documentation - ds_ping_interval With this parameter you can define the interval for sending a request to a gateway marked as inactive upon a failed request routing to it. ds_probing_threshold If you want to set a gateway into inactive mode, there can be a specific number of failed requests until it will change from "active" to "inactive". Thanks, -dan

Regular Expression Syntax
by Duarte Rocha 27 Mar '18

27 Mar '18

Greetings, I'm having some trouble with the syntax used in the {re.subst,expression} method. What i want to do is add a prefix to a capture group. I can make it work like that /^[0-9]+/prefix$tU/ but this solution is far from perfect since i may not need the entire $tU. I would like to use it like this /^[0-9]+/prefix\1/ in order to not limit my regex to Kamailio only. When i do it like this the regex result is only "prefix". What's the correct syntax to add a prefix using the capture group ? Thanks in advance

topos_redis and session-timer timeouts
by Daniel Tryba 27 Mar '18

27 Mar '18

I was testing topos with a mysql backend and all was fine. But since the purpose of this machine doesn't require a complete mysqlserver I tried the redis backend. With redis the calls will drop after some timeout (somewhere < 450 seconds (session timer set to 900)). Config: # topos modparam("ndb_redis", "server", "name=srv2;addr=127.0.0.1;port=6379;db=2") modparam("topos", "storage", "redis") modparam("topos_redis", "serverid", "srv2") #modparam("topos", "storage", "db") #modparam("topos", "db_url", DBURL) modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "branch_expire", 180) modparam("topos", "dialog_expire", 10800) modparam("topos", "clean_interval", 60) The call will end on the first session-time firing with a "404 Not here" Debug contains: Mar 27 12:20:56 kam kamailio[11649]: DEBUG: topos_redis [topos_redis_storage.c:962]: tps_redis_load_dialog(): loading dialog record for [d:z:atpsh-5aba19b2-2d7f-2] Mar 27 12:20:56 kam kamailio[11649]: DEBUG: ndb_redis [redis_client.c:878]: redisc_exec_argv(): rsrv->ctxRedis = 0x55a7c8da8500 Mar 27 12:20:56 kam kamailio[11649]: DEBUG: topos_redis [topos_redis_storage.c:980]: tps_redis_load_dialog(): hmap with key [d:z:atpsh-5aba19b2-2d7f-2] not found This records was inserted/updated: Mar 27 12:17:10 kam kamailio[11647]: DEBUG: topos_redis [topos_redis_storage.c:253]: tps_redis_insert_dialog(): inserted dialog record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 26 Mar 27 12:17:10 kam kamailio[11647]: DEBUG: topos_redis [topos_redis_storage.c:282]: tps_redis_insert_dialog(): expire set on dialog record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 3 Mar 27 12:17:11 kam kamailio[11648]: DEBUG: topos_redis [topos_redis_storage.c:962]: tps_redis_load_dialog(): loading dialog record for [d:z:atpsh-5aba19b2-2d7f-2] Mar 27 12:17:11 kam kamailio[11648]: DEBUG: topos_redis [topos_redis_storage.c:1293]: tps_redis_update_dialog(): updated dialog record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 6 Mar 27 12:17:11 kam kamailio[11648]: DEBUG: topos_redis [topos_redis_storage.c:962]: tps_redis_load_dialog(): loading dialog record for [d:z:atpsh-5aba19b2-2d7f-2] Mar 27 12:17:11 kam kamailio[11648]: DEBUG: topos_redis [topos_redis_storage.c:1293]: tps_redis_update_dialog(): updated dialog record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 6 Mar 27 12:17:11 kam kamailio[11650]: DEBUG: topos_redis [topos_redis_storage.c:962]: tps_redis_load_dialog(): loading dialog record for [d:z:atpsh-5aba19b2-2d7f-2] Mar 27 12:17:11 kam kamailio[11650]: DEBUG: topos_redis [topos_redis_storage.c:962]: tps_redis_load_dialog(): loading dialog record for [d:z:atpsh-5aba19b2-2d7f-2] Mar 27 12:17:11 kam kamailio[11650]: DEBUG: topos_redis [topos_redis_storage.c:1381]: tps_redis_end_dialog(): updated on end the dialog record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 6 Mar 27 12:17:11 kam kamailio[11650]: DEBUG: topos_redis [topos_redis_storage.c:1412]: tps_redis_end_dialog(): expire set on branch record for [d:z:atpsh-5aba19b2-2d7f-2] with argc 3 It looks like the last update/expire sets the timeout to 180s, so the not found is reasonably expected.

Kamailio Call monitoring
by Tomi Hakkarainen 27 Mar '18

27 Mar '18

Hi you all, I have set up Kamailio and RTPProxy in front of Asterisk. Currently successfully able to route calls from two differrent SIP-Trunk providers terminated to Kamailio and RTPProxy. I would like to get a view of calls currently running through Kamailio? I should be able to see some details about the call like the calling called numbers and the time call has been active. I’m not sure if Siremis would provide such view. Also looked Homer and also not sure it has something like that. Still those provide much more like for troubleshooting. If anyone has idea how that would be possible to accomplish or know that there already is such implementation I would be interested. Tomi

Kamailio NAT AWS EC2
by Ilie Soltanici 27 Mar '18

27 Mar '18

Hi, First of all, check if SIP Traffic is going through your SIP Server, not directly between Endpoints. To do this check if Record-route parameter is set in configuration file: record_route(); https://www.kamailio.org/docs/modules/5.1.x/modules/rr.html Also, be sure that in SDP body you have External IP of your Kamailio/RTPproxy. If Kamailio is behind NAT you may need to use fix_nated_sdp function from nathelper module: https://www.kamailio.org/docs/modules/5.1.x/modules/nathelper.html#nathelpe… Regards,

NOTIFY message without XML part
by denislav.tsonev＠musala.com 27 Mar '18

27 Mar '18

Hello, I use kamailio 5.1.1 with default configuration for PRESENCE: Route: #!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if(is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); } exit; #!endif and modparams: #!ifdef WITH_PRESENCE # ----- presence params ----- modparam("presence", "db_url", DBURL) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) #!endif I use and GRANSTREAM phones. When I make subscribe from soft sip client (Micro sip) to the grandstreams, all NOTIFY messages are without XML. Subscriptions between two soft sip clients like Zoiper and Micro SIP works perfectly. Is this related to GRANDSTREAM phones - configuration or so... or is necessary to modify kamailio configuration and if Yes, please provide some hitns how to change kamailio config? Thanks in advance.

Strange auth_challenge behaivor on 407
by Yuriy Gorlichenko 27 Mar '18

27 Mar '18

Hi I'm using version: kamailio 5.1.2 I have strange issue with auth_challenge kamialio works as NAT handler. When Register comes kamailio handles nat and save original ip:port at the received field in location table I found that when local port in contact is different than external port reply 407 on INVITE comes to externalip (from received) : internalport(from contact) And never reaches destination for exmaple Register comes from 192.168.1.10:50555 Kamailio saves at the Received 12.1.1.12:1030 but when invite comes form 12.1.1.12:1030 kamailio sends reply to 12.1.1.12:50555 i don't think that this is an issue in kamailio source code but i can find where i can configure it

Best approach for Kamailio behind nat
by Evgeny Kuchkov 25 Mar '18

25 Mar '18

Sorry for my previous mail with typos. I have the current configuration located on google cloud servers: [Alice a.a.a.a]--->(GCN NAT x.x.x.x)--->(Instance with Kam 10.0.0.1)--->(next proxy 10.0.0.2) Currently I have configured a fake alias with IP x.x.x.x in Debain and set listeners this way: listen=udp:10.0.0.1:5060 advertise x.x.x.x:5060 listen=udp:x.x.x.x:5060 200OK from Kam to Alice: Via: a.a.a.a Record-Route: <sip:alias1@10.0.0.2;lr> (used for further internal routing) Record-Route: <sip:alias2@10.0.0.2;lr> Record-Route: <sip:x.x.x.x;lr> Contact: <sip:dnis@x.x.x.x> ACK recived from Alice with reversed RR: ACK sip:dnis@x.x.x.x Via: a.a.a.a Route: <sip:x.x.x.x;lr>, <sip:alias2@10.0.0.2;lr>,<sip:alias1@10.0.0.2;lr> So what Kam does - it goes through loose_route() and dispatches two ACKs to x.x.x.x (from which I'd like to get rid of) and 10.0.0.2 First one is: ACK sip:alias1@10.0.0.2 Via: x.x.x.x Via: a.a.a.a Route: <sip:x.x.x.x;lr>, <sip:alias2@10.0.0.2;lr> And the next one: ACK sip:alias1@10.0.0.2 Via: x.x.x.x Via: x.x.x.x (Doubles Via) Via: a.a.a.a Route: <sip:alias2@10.0.0.2;lr> So my question is - how to make Kam think that x.x.x.x it's own address and stop dispatching in-dialog messages to itself? Currently I'm thinking about chooping off one Route/Record-Route in route[WITHINDLG] tight before loose_route(). But maybe there's a better way to solve my problem?

dlg_manage() and dlg_flag
by Alex Balashov 24 Mar '18

24 Mar '18

Hi, One aspect of the dialog module that is very confusing to newbies is the relationship between the dlg_flag modparam and dlg_manage(). According to the documentation, dlg_manage() effectively seems to obsolete the requirement for a flag[1]: Process current SIP request with dialog module. It is an alternative to setting dialog flag for initial INVITE and Route-parameter-callback execution for within-dialog requests. Yet, if one does not set a dlg_flag modparam, the dialog module fails to load: Mar 23 15:42:29 evaristesys-legacy /usr/local/sbin/kamailio[2900]: ERROR: dialog [dialog.c:500]: mod_init(): invalid dlg flag -1!! Perhaps the flag modparam should be made optional, and any arguments for using one over the other more clearly explained in the documentation. I'd make the latter contribution, but unfortunately am not entirely sure what those are.

tcpconn_main_timeout
by Kjeld Flarup 23 Mar '18

We are developing an app with a pjsip client. I see this error when trying to send an invite from kamailio. Mar 17 00:29:46 raspberrypi /usr/sbin/kamailio[18720]: ERROR: <core> [tcp_main.c:4258]: tcpconn_main_timeout(): connect 62.44.134.85:43829 failed (timeout) A few seconds before 62.44.134.85:43829 did a register. I can understand that either the TCP connection was close by the other end or no one is listening. How much can I see in a pcap from this scenario? I cannot see the invite, but somehow there must be some TCP communication to show what is failing. -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 49 Den ikke akademiske hjemmeside for liberalismen - www.liberalismen.dk

phonenum module erratic behaviour with 5.1.2

Hello all, It seems that the phonenum module in at least 5.1.2 (haven't tried previous versions) is behaving somewhat erratically.

For example: phonenum_match("14~8%^88", "src") will result in dbg_pv_dump reporting: "$phn(src=>number)": "14~8%^88" Please note that I'm using sipwise's debian repository for stretch for kamailio, and debian's stable stretch repository for libphonenumnber (currently at 7.1.0-5+b1). I have also tried building current libphonenumber myself (version v8.9.2), but the result is the same. Is this a bug? Or am I missing something? Thanks! BR, George

Hello there, I have an htable with 3000 entries and when i try dump the htable through the command kamcmd htable.dump htable, this command returns "ERROR: reply too big".

Kamailio behind NAT no Audio
by Benjamin Marty 22 Mar '18

22 Mar '18

Hi, I am new to Kamailio and coming a bit from the Asterisk side. Currently I'm using the Amazon EC2 Infrastructure and set up an Kamailio with standard configuration. EC2 uses Destination NAT on their side. Thus I enabled WITH_NAT and WITH_NATSIPPING. I'm using the rtpproxy from master branch of https://github.com/miconda/rtpproxy. Besides those two parameters I also changed the listen parameter in the Kamailio config: listen=udp:10.0.0.221:5060 advertise 52.59.XXX.XXX:5060 My rtpproxy is running with following parameters: ./rtpproxy -A 52.59.XXX.XXX -F -l 10.0.0.221 -m 20000 -M 30000 -s udp:*:7722 -d INFO When I use two Softclients (Zoiper) on different Networks (with Source NAT on the Firewall) the Softclient tries to transmit the RTP Packets to the Public IP of the other Network. But the Client obviously thus doesn't get the RTP Packets. Is there an easy and documented way to solve that issue? If I understood it correctly Kamailio together with rtpproxy should be able to receive the RTP Packets and forward them to the other client. So it should signal the IP of the Kamailio to send the RTP packets to. Or am I on the complete wrong way? Regards, Benjamin

drouting & rd
by Jean Cérien 22 Mar '18

22 Mar '18

Hello I have setup 2 gateways in my dr_rules: 5,6 - so the 2nd one is tried if the first fails. The second one requires credentials. When the first one fails: I execute the following code: failure_route[ROUTEFAIL] { if ( t_check_status("[345][0-9][0-9]") or (t_branch_timeout() and !t_branch_replied() )) { t_on_failure("ROUTEFAIL"); if (use_next_gw()) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ routing to: rd: $rd, ru:$ru, t_relay"); t_relay(); exit; } then in the same ROUTEFAIL (before this code), I have if (t_check_status("401|407")) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ call to uac_auth(), $si rd: $rd\n"); ..... So, when the first gateway replies with a 404, it executes correctly the first block, finds the second gw and I see in the log that rd is set to its address. Yet, when the 2nd gw replies with 401, rd is set to the very first gw. However, the pcap traces confirm it is indeed the second that replies this. If this behaviour is correct, I cant seem to find the source IP of the gateway that replied to me, to retrieve credentials from the db. version: kamailio 5.0.5 / 5.0.6 (tested on both) Thank you for your help J
