Syntax issue?
by Igor Potjevlesch 17 Feb '15

17 Feb '15

Hello, I'm looking for a way to track a call by using basic AVP like this: Into a route that treats INVITE: $avp(s:state)="call_start"; Then, if I test this AVP into WITHINDLG route: if($avp(s:state)!="call_start") ; the test fails. Did I miss something? The goal is to update this AVP during the life of the transaction. Regards, Igor.

selective logging with debugger module
by Sharath Kumar 16 Feb '15

16 Feb '15

Hello, I followed the documentation from http://kamailio.org/docs/modules/4.2.x/modules/debugger.html#idp84752. I have the global debug flag at 9. modparam("debugger", "cfgtrace", 1) modparam("debugger", "mod_level_mode", 1) modparam("debugger", "mod_level", "core=3") My Kamailio complains with a parsing error of some sort and fails to start. - "dbg_mod_level_param(): cannot store parameter: core=3" My intention is to turn off/reduce the "core" module tracing while keeping the "script" module at debug. Any suggestions ? I am running version 4.1.4. thanks Sharath

Amazon VPS, long UDP packets are seen by sniffer, but don't reach application
by Andrey Utkin 16 Feb '15

16 Feb '15

We experience strange networking issue, not exactly specific to kamailio, but still related to it. Rtpengine's "ng" interface uses UDP. Protocol messages contains SDP, and for encrypted video call those messages exceed 1500 bytes. Everything works fine within localhost, but when rtpengine and Kamailio are on different hosts, and when hosts are Amazon-hosted, we have trouble. This is experienced with l3.large, t2.micro with Ubuntu 14. I believe we don't have any special settings over system defaults. We send a large datagram from remote host, e.g. with such trivial app in python: import socket UDP_IP = "123.123.123.123" # remote host IP UDP_PORT = 33333 MESSAGE = """ .....0010......0020......0030......0040......0050......0060......0070......0080......0090......0100 .....0110......0120......0130......0140......0150......0160......0170......0180......0190......0200 .....0210......0220......0230......0240......0250......0260......0270......0280......0290......0300 .....0310......0320......0330......0340......0350......0360......0370......0380......0390......0400 .....0410......0420......0430......0440......0450......0460......0470......0480......0490......0500 .....0510......0520......0530......0540......0550......0560......0570......0580......0590......0600 .....0610......0620......0630......0640......0650......0660......0670......0680......0690......0700 .....0710......0720......0730......0740......0750......0760......0770......0780......0790......0800 .....0810......0820......0830......0840......0850......0860......0870......0880......0890......0900 .....0910......0920......0930......0940......0950......0960......0970......0980......0990......1000 .....1010......1020......1030......1040......1050......1060......1070......1080......1090......1100 .....1110......1120......1130......1140......1150......1160......1170......1180......1190......1200 .....1210......1220......1230......1240......1250......1260......1270......1280......1290......1300 .....1310......1320......1330......1340......1350......1360......1370......1380......1390......1400 .....1410......1420......1430......1440......1450......1460......1470......1480......1490......1500 .....1510......1520......1530......1540......1550......1560......1570......1580......1590......1600 .....1610......1620......1630......1640......1650......1660......1670......1680......1690......1700 .....1710......1720......1730......1740......1750......1760......1770......1780......1790......1800 .....1810......1820......1830......1840......1850......1860......1870......1880......1890......1900 .....1910......1920......1930......1940......1950......1960......1970......1980......1990......2000""" print "UDP target IP:", UDP_IP print "UDP target port:", UDP_PORT print "message:", MESSAGE sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.sendto(MESSAGE, (UDP_IP, UDP_PORT)) Then we listen on that port with such trivial python app: import socket UDP_IP = "172.31.4.102" # local ip UDP_PORT = 33333 sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.bind((UDP_IP, UDP_PORT)) while True: data, addr = sock.recvfrom(0x10000) print "received message:", data Meanwhile, we monitor the traffic with e.g. ngrep: ngrep -t -e -d any -W byline -O large_udp.pcap port 33333 or '(ip[6:2]' '&' '0x1fff)' '!=' '0' (the part after "or" catches segments of segmented packets) About the host: # uname -a Linux hostname 3.16.0-30-generic #40~14.04.1-Ubuntu SMP Thu Jan 15 17:43:14 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Also linux-image-3.13.0-36-generic and linux-image-3.13.0-45-generic behave in same way. What we see: - ngrep shows the packets with correct contents. All segments are delivered. - application doesn't get any data at all Rarely dmesg shows such messages: [ 102.161679] UDP: bad checksum. From 123.123.123.124:56439 to 172.31.4.102:33333 ulen 2008 but it is logged really rarely, so this is surely not what happens on every packet transmission. This test works fine on e.g. cheapest DigitalOcean VPS. I am concerned with this issue because rtpengine software has UDP interface. So on Amazon hosts this interface works only within localhost, and I cannot distribute software to different nodes. Any thoughts? What's wrong, how to fix? -- Andrey Utkin

Event reg - questions
by Stefan Ljung 16 Feb '15

16 Feb '15

I made a test configuration for trying the pua_regEvent module. There were two things I want to ask about. First - when the SUBSCRIBE to event 'reg' following a UEs registration to the Kamailio is responded with a NOTIFY - there was no body in the NOTIFY. I expected a XML body with registration status. Second - When the UE re-registers to Kamailio - I expected a NOTIFY to be send on the existing 'reg' subscription, but nothing happened. Or am I missing some configuration ? Here's some of the conf script: ####### Modules Section ######## loadmodule "db_mysql.so" loadmodule "mi_fifo.so" loadmodule "kex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "mi_rpc.so" loadmodule "xcap_client.so" loadmodule "pua.so" loadmodule "pua_reginfo.so" loadmodule "presence.so" loadmodule "presence_reginfo.so" loadmodule "presence_xml.so" # ----------------- setting module-specific parameters --------------- #!define DBURL "mysql://kamailio:kamailiorw@localhost/kamailio" # ----- xlog params ----- modparam("xlog", "prefix", "-xlog: ") # ----- mi_fifo params ----- modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # default retransmission timeout: 30sec modparam("tm", "fr_timer", 30000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 120000) # ----- rr params ----- # add value to ;lr param to cope with most of the UAs modparam("rr", "enable_full_lr", 1) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 0) # ----- registrar params ----- modparam("registrar", "method_filtering", 1) modparam("registrar", "max_expires", 86400) # ----- pua_reginfo params ----- modparam("pua_reginfo", "default_domain", "system.test") modparam("pua_reginfo", "server_address", "sip:reginfo@10.171.0.4") modparam("pua_reginfo", "publish_reginfo", 0) modparam("pua_reginfo", "default_domain", "system.test") # ----- presence_xml params ----- modparam("presence_xml", "integrated_xcap_server", 1) # ----- presence params ----- modparam("presence", "db_url", DBURL)

dialog module 4.2 REFER
by Uri Shacked 16 Feb '15

16 Feb '15

Hi, I am trying to use dlg_refer. I set the side to refer and the final destination. But, the contact header of the refer stays "controler(a)kamailio.org". So, the refer fails. Is it a bug or should i change the contact header by myself before doing the dlg_refer? same with the dlg_bridge..... Cheers, Uri

Using dialog_ng
by Shane Harrison 15 Feb '15

15 Feb '15

Hi all, I think the lack of response to my previous thread is probably because it was too complicated. I have now narrowed my problem down after further archive readings . I am trying to use the dialog_ng module along with the ims_charging_module. Upon reception of an INVITE, a call to the Ro_CCR() from the request_route script is made. That function does a check that the dialog record exists (binds to dialog module and does a "get_dlg(msg)" call) - this fails i.e. dialog is not found. Running kamailio 4.2.2 and relevant sections of kamailio.cfg are: modparam("dialog_ng", "dlg_flag", FLT_DIALOG) modparam("dialog_ng", "timeout_avp", "$avp(DLG_TIMEOUT_AVP)") modparam("dialog_ng", "detect_spirals", 1) modparam("dialog_ng", "profiles_no_value", "orig ; term") request_route { # NAT detection route(NATDETECT); # Set DLG flag to track dialogs using dialog2 if (!is_method("REGISTER|SUBSCRIBE")) setflag(FLT_DIALOG); # handle requests within SIP dialogs route(WITHINDLG); ### only initial requests (no To tag) # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } t_check_trans(); if (is_method("INVITE")) { set_dlg_profile("orig"); Ro_CCR("CHARGING_CCR_REPLY", "orig", "SCUR", "", "30","CCR_location"); } So my question is, "should the above logic create a dialog record on the initial INVITE?" and if yes then "what possible reasons might there be for the Ro_CCR() function not be able to detect it exists?" Cheers Shane Harrison

Kamailio and rtpengine
by Marc Soda 14 Feb '15

14 Feb '15

How does Kamailio load balance traffic to rtpengine? Is it load based, round robin, etc? The module makes mention of this but I don't see how it works. Also, it talks about weighting the proxies. How is that accomplished? Thanks, Marc

WebRTC to PSTN call, proxied through Kamailio
by Rahul MathuR 14 Feb '15

14 Feb '15

Hello gents, I was trying my hands on getting a successful RTCweb call (JSsip, since Peter Dunkley mentioned that he's been using JSsip for most of the testing scenarios..) to PSTN, making my kamailio as proxy + protocol converter (sip over web-sockets to sip over udp). And yes, I've referred Carlos' config; the main problem is I get 'Bad Media Description' error in Google Chromium (Version 40.0.2214.111 m) & my SIP server even sends 200 OK, but my phone doesn't ring. To make it worse, I can see rtpengine throwing this error - "SRTCP output wanted, but no crypto suite was negotiated" BTW, I have - [root@localhost log]# openssl version OpenSSL 1.0.1j 15 Oct 2014 I even tried building kamailio & rtpengine using this openssl but in-vain. One thing that baffles me is that, apparently kamailio has started receiving RTP packets (perhaps early media) but the mobile phone hasn't ringed :-( I am attaching all possible logs & seek some guidance from the array of experts in this list. Files attached: a) tcpdump on ext. interface b) tcpdump on loopback c) syslogs d) Chromium JS logs UAC (14.98.55.38), Kamailio (125.99.186.126), SIP Server (157.238.178.153), Media Server (199.27.244.6) -- Warm Regds.
