Parameters list transformations comma and semi column conflict

by Seudin Kasumovic

Hi, Transformation {param.value, param_name} returns incomplete or empty values when parameter value contains comma (,). See next example: *$avp*(my_var)="a=val_a1,val_a2,val_a3;b=val_b"; in next transformations: $(*avp*(my_var){param.value, a}) returns 'val_a1' $(*avp*(my_var){param.value, b}) returns empty string Seams that comma in parameter value conflicts with semi column separator. Is this bug or wrong documented? Related link: http://www.kamailio.org/wiki/cookbooks/4.0.x/transformations#paramvalue_name -- Seudin Kasumovic Tuzla, Bosnia

Loop detected on aws setup

by julian arsanches

Hi all, before hand thanks for all the support received on this channel. I have an issue with an installed server on a aws instance which is giving me routing loops, my setup is simple, i have alias set for both ips internal and external and the loop still present when t_relay don't find any routes to relay it just sent it to itself with the public ip then the loop starts. can any one please advise how can i prevent that or just tell t_relay that if there is no more routes just respond with a cancel or stop searching. same thing happens when a gw code is not found on the dispatcher list file. as i had read by just specifying the alias=domain it should take care of it but it is not happening perhaps because it is a AWS instance, or most likely i am missing something after the T_relay to stop the call from looping. I do have several headers fix because i have an asterisk sending calls with lots of signalling calls added to the call that i need to remove before the call is passed out to a carrier or another UA, Kamailio is just proxing the calls between asterisk and the outside world no Media handling, No registrations. Again thanks for any tips to find my answer or if anyone had a similar issue thanks again. thanks for any help . Julian. on this setup i have public ip as 2.2.2.2 private IP as 1.1.1.1 #!KAMAILIO ####### Global Parameters ######### #!ifdef WITH_DEBUG debug=4 log_stderror=yes #!else #debug=2 #log_stderror=yes #!endif memdbg=5 memlog=5 log_facility=LOG_LOCAL7 fork=yes children=6 auto_aliases=no listen=udp:1.1.1.1:5060 advertise 2.2.2.2:5060 alias=1.1.1.1:5060 alias=1.1.1.1 alias=2.2.2.2:5060 alias=2.2.2.2 port=5060 enable_tls=no #tcp_connection_lifetime=3605 #!ifdef WITH_SRCPATH mpath="modules_k:modules" #!else mpath="/usr/lib64/kamailio/modules_k/:/usr/lib64/kamailio/modules/" #!endif loadmodule "db_mysql.so" ##loadmodule "mi_fifo.so" loadmodule "tm.so" loadmodule "sl.so" loadmodule "acc.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "uac.so" loadmodule "textops.so" loadmodule "pv.so" loadmodule "dispatcher.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "siputils.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "mi_rpc.so" loadmodule "avpops.so" #!ifdef WITH_NAT loadmodule "nathelper.so" loadmodule "rtpproxy.so" #!endif loadmodule "xlog.so" ##mysqlcdr modparam("acc", "db_flag", 2) modparam("acc", "db_missed_flag", 3) modparam("acc", "report_cancels", 1) modparam("acc", "db_url", "mysql://openser:password@1.1.1.2/openser") modparam("acc", "db_extra", "from_uri=$fu;

Need help on RTP port opening!!!

by Vinay Krishna

Hi Sir/Madam, I want to make a call across firewall device. I am using nf_conntrack_sip and nf_nat_sip(2.6.32) kernel modules as sip proxy. Connection got established from private network to public network but *no voice exchange is happening*. We can see RTP ports related UDP entry in conntrack -L. How can I fix this problem? Test Scenario: --------------- Device LAN IP -- 10.0.0.1 Device WAN IP -- 192.168.1.1 LAN side of device ------------------ Analog phone with ATA(10.0.0.3) Trixbox(Asterisk) - 10.0.0.2 WAN side of device ------------------ PC with SJphone - 192.168.1.2 I am trying to establish the connection from Analog phone to SJphone. In the device iptable rule added in FORWARD chain to allow SIP packet(5060 port). In NAT table under POSTROUTING chain MASQUERADE rule to allow packets to traverse from LAN side to WAN side. Thanks in advance. Regards, Vinay Krishna K

Memory leak in 3.3.4

by David Cunningham

Hello, We're running a Kamailio 3.3.4 system, and Kamailio is slowly using more and more memory. Over a couple of weeks it will run out of system memory. We tried to enable memory debugging doing the following, but it resulted in Kamailio not responding to any SIP packets. Would anyone have advice please on how to debug the situation? 1. In Makefile.defs set MEMDBG to 1 and recompile Kamailio. 2. In kamailio.cfg add the line: #!define DEBUG_MEMORY 1 While this was running and Kamailio didn't respond to packets, it logged lots of lines like this: Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]: qm_malloc(0x4000e008, 128) called from <core>: cfg.lex: addstr(1438) Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]: qm_malloc(0x4000e008, 128) returns address 0x40048918 frag. 0x40048900 (size=128) on 1 -th hit Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]: qm_malloc(0x4000e008, 128) called from <core>: cfg.lex: addstr(1438) Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]: qm_malloc(0x4000e008, 128) returns address 0x400489c8 frag. 0x400489b0 (size=128) on 1 -th hit Thanks in advance, -- David Cunningham, Voisonics http://voisonics.com/ USA: +1 213 221 1092 UK: +44 (0) 20 3298 1642 Australia: +61 (0) 2 8063 9019

Kamilio and AWS Route 53 latency regions

by Coy Cardwell

Hi All. Fist time poster here, long time geek. I am trying to get Kamilio to work in the following configuration and after days of googling and configuration attempts, I have come here for help. Two servers, both sharing the same database. Server1, Server2. Both servers are behind a NAT (AWS). If I set the DNS to return both IP addresses for the domain on the A record, everything works, all is well. If I set the DNS to return values based on latency and the Calling Client gets Server1's IP Address but the Receiving Client is registered to Server2, the call fails from a timeout. I can see the attempt to go through at the packet level and a 'non-local' socket message as well. If the DNS returns Server2's IP Address and the Receiving Client is registered to Server2, the call completes. I have tried numerous variations of the various 'path' and 'registrar' options with any joy. I tried making one of the servers the central registrar as well. I am not entirely sure I ever set everything correctly, but I have tried numerous combinations. Any thoughts would be appreciated, I only ask this as I think I have exhausted my own list of things to try. Thanks. - Coy Cardwell
