Hi All, Kamailio send 2 Invite request for Client behind NAT. due to this reason for one request,Client respond with 486 Busy here. we only want to send 1 INVITE request. Following are the AOR for client at kamailio.if field(ip port) in CONTACT and RECEIVED differ then kamailio send 2 INVITE request. Please advice if there is any way to send only ONE INVITE*.* AOR:: 123 Contact:: sip:123@*192.168.230.124:45672 <http://192.168.230.124:45672>* Q=1 Expires:: 894 Callid:: 003A8EC4-12351(a)192.168.230.124 Cseq:: 2 User-agent:: SIPPER for 3CX Phone Received:: sip:*204.192.206.208 <http://204.192.206.208>: 45672 * State:: CS_NEW Flags:: 0 Cflag:: 192 Socket:: udp:172.12.120.88:5060 Methods:: 4294967295 Ruid:: uloc-5aba112d-7fce-5 Reg-Id:: 0 Last-Keepalive:: 1522144583 Last-Modified:: 1522144583 thanks, amit

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. Best regards.

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

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
by George Diamantopoulos 22 Mar '18

22 Mar '18

Hello all, It seems that the phonenum module in at least 5.1.2 (haven't tried previous versions) is behaving somewhat erratically. More specifically, if there are any references to any phn PVs with the key other than "number": if ( phonenum_match("1-484-555-8888", "src") ) { xlog("number norm: $phn(src=>number)\n"); xlog("number country: $phn(src=>country)\n"); dbg_pv_dump(30, "L_ERR"); } kamailio will not start: Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) DEBUG: <core> [core/pvapi.c:494]: pv_spec_lookup(): PV <$phn(src=>country)> is not in cache Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) DEBUG: phonenum [phonenum_pv.c:160]: pv_parse_phonenum_name(): phonenum [src] - key [country] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: phonenum [phonenum_pv.c:205]: pv_parse_phonenum_name(): error at PV phonenum name: src=>country Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: <core> [core/pvapi.c:951]: pv_parse_spec2(): pvar "phn" has an invalid name param [src=>country] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: <core> [core/pvapi.c:1106]: pv_parse_spec2(): wrong char [)/41] in [$phn(src=>country)] at [17 (5)] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: xlog [xlog.c:513]: xdbg_fixup_helper(): wrong format[number country: $phn(src=>country) If I comment the offending line, all is well, but when dumping PVs with dbg_pv_dump(30, "L_ERR");, only $phn(src=>number) is listed, not the other keys (country, operator, region according to the docs) However, what is more disturbing is that phn(src=>number) always contains the string provided to phonenum_match() function, even if invalid characters are included, with no normalization. For example: phonenum_match("14~8%^88", "src") will result in dbg_pv_dump reporting: "$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

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

How does Kamailio decide which msg to store when receiving it double from 2 servers?
by Zigelman, Amit 21 Mar '18

21 Mar '18

I am using Captagent on 2 sip servers communicating with each other. Both Captagents then route the SIP traffic to the same Kamailio. Therefore, if I understand, Kamailio will get every msg between them twice. Once from server A and once from server B. Let's say that each of them has a different capturing code (100 for server A and 200 for server B) How will the data look in the DB? Will it hold both entries pretty much the same with a difference is some fields such as the capture node? Thanks a lot, Amit -- *Amit Zigelman* | *Software Developer* Mobile (+972) 54-570-9129 <+972%254-570-9129> | amit.zigelman(a)vonage.com

authenticating to mongodb fails
by hdssdsdsdsfsdf hdssdsdsdsfsdf 21 Mar '18

21 Mar '18

When I connect using mongo, the credentials work: $ mongo kamailio -u "kam" -p "kam" MongoDB shell version v3.4.9 connecting to: mongodb://127.0.0.1:27017/kamailio MongoDB server version: 3.4.9 > db.subscriber.find() { "_id" : ObjectI ... But when I use the following DBURL in kamailio.cfg, kamailio fails to even login to mongo: #!define DBURL "mongodb://kam:kam@localhost/kamailio" If I disable mongodb authentication, kamailio starts up just fine again. Any idea what's going wrong here?

NATDETECT Flag 16
by Duarte Rocha 21 Mar '18

21 Mar '18

Greetings, I have a doubt about the flag 16 used in nat_uac_test() belonging to the module NATDETECT. In the documentation, the following is stated : *16* - Test if the source port is different from the port in the “Via” header I have some situations that I receive a request from port 5060 and the Via Header contains no port. I think it probably assumes that it is the default port. Will this situation trigger the "16" flag ? Thanks in advance, Cheers

S-CSCF can not allocate memory
by tyd 21 Mar '18

21 Mar '18

Hello, I haved install debian 8 and kamailio 4.4.7 for IMS testing. After registering 10000 users, SIPp generates CPS 25 SIP INVITE message and BYE message after 100 seconds. After about 240000 calls, there are "cannot allocate memory" messgae on S-CSCF. The command of S-CSCF is "kamailio -m 512 -f /etc/scscf/kamailio.cfg" The parameter mem_join=1 is included in kamailio.cfg. I have modified the share memory to 1024 and 2048, but the result is the same, just increasing the pass calls. Would you please tell me how to solve the memory problem? Thanks.
