terminate call when dialog when remote contact disappears without BYE

by Thibault Gueslin

I would like to terminate the dialog when one party disconnects without sending a BYE (no more connctivity, client shutdown) I am using TCP connection. Should I terminate the dialog from event_route[usrloc:contact-expired] ? I have tried also to use SIP OPTION parameter from dialog module modparam("dialog", "ka_timer", 10 ) modparam("dialog", "ka_interval", 30 ) but nothing is sent) thibault

SQLOPS vs APP_LUA

by Luke Milbourne

Hi All, I need to run some SQL and then set the destination URI according to the results, if any. I've got this working using APP_LUA, however, I've noticed SQLOPS. Can anyone advise on which method is likely to produce better results. I'm assuming my Lua function is connecting to the DB and then disconnecting each time. If I use SQLOPS, does this mean Kamailio will keep a connection available to the DB? -- Luke Milbourne <luke.milbourne(a)gmail.com> Tel: 07857154817 Google Talk/Email: luke.milbourne(a)gmail.com

using APP_LUA for complex arithmetic operations

by Jayesh Nambiar

Hi, I understand that kamailio does not allow float-point values in variables and I think kamailio is not a great place to do complex arithemtic operations and so I thought of using app_lua for the same. So can I pass the control to app_lua and come back to config script with some values? For eg. can I call a lua script that does a complex arithemetic operation on my AVP values and based on certain conditions; return back a true or false and then I continue in my existing script. I came across an exmaple http://kb.asipto.com/kamailio:usage:k32-lua-routing but this is more like doing the entire thing inside LUA. What I'm looking at is getting certain things done in lua and continue the script processing. Thanks for any help here. - Jayesh

Kamailio - Asterisk, problem with SIP trunk mode

by Mickael MONSIEUR

Hello, First, i have 7 years experience with Asterisk, but I started a project with Kamailio, forgive me in advance if I say silly things...! ;-) I set up a classic Asterisk / Kamailio configuration: sip phones -> kamailio -> asterisk -> sip trunks/pstn. When a call comes from the PSTN side, if I configure Asterisk as follows: [012345678] type = friend username = 012345678 secret = xxxxxxx host = dynamic fromdomain = sip.mydomain.com fromuser = 012345678 Standard mode: exten => 012345678, 1, Dial(SIP/012345678) -> The call is redirected on the phone by Kamailio ! :-) ------------------------------------------------------------------------------------------------------------------------------------------------ Trunk mode: [mytrunk] type = friend username = mytrunkUser secret = xxxxxxx host = dynamic fromdomain = sip.mydomain.com fromuser = mytrunkUser exten => 012345678, 1, Dial(SIP/mytrunk/012345678) -> The call is rejected by Kamailio.... exten => 012345679, 1, Dial(SIP/mytrunk/012345679) -> The call is rejected by Kamailio .... My question is how to allow the routing of multiple numbers (trunk mode) in a SIP account with Kamailio? Best regards, Mickael

Record-route on sequential requests

by Kristian F. Høgh

Hi list, Record-route on sequential requests doesn't have did/vsf parm. On initial INVITE, I call record_route() and set dialog flag. kamailio adds the following RR Record-Route: <sip:ww.xx.yy.zz;lr;ftag=15af612df;vsf=AAAA....;did=4a8.3ca2> UAC sends a re-INVITE, containing the following route: Route: <sip:178.21.251.54;lr;ftag=15af612df;vsf=AAAA....;did=4a8.3ca2> I call loose_route() followed by record-route(), and kamailio adds the following RR: Record-Route: <sip:ww.xx.yy.zz;lr;ftag=15af612df> I've got a phone which updates the routeset on sequential requests (which I don't think it should) and the did-matching fails. Should kamailio add did/vsf on sequential requests, when I call record_route()? Should I set dlg_match_mode to 1? (I use 0) Is it wrong to call record_route() from sequential requests? Which way is the best to resolve the problem? Regards, Kristian Høgh Uni-tel A/S

Problem with NATed UAC

by Vladimir Stepic

Hello everyone, this is my first message. I'm glad to become a part of this big community. I'm new in SER technology. I worked in Asterisk PBX only, until now. For the first time i installed Elastix MT witch have kamailio in front of asterisk, and now i have a problem. I attach a diagram of initial configuration in my lab and pcap file and kamailio.cfg. Regardless diagram, x.x.x.x addresses are public and y.y.y.y are private. When i test connection 1.1 is working, connection 1.2 not working connection 2.2 not working connection 1.3 not working connection 2.3 working Phones are connected(authenticate) to kamailio, but when i look at asterisk cli those phones are unreachable, but can call, but can not be called. On router where android works, Siemens dont, and where pc softphone works other UAC dont work. I think that my nat-traversal configure good, regardless of documentation. Please tell me, if someone has some ideas of solve this problem. Thanks in advance, and sorry for my bad english :) ---------------------------------------------------------------------- *Vladimir Stepić,* Engineer specialist in computer networking System Linux Administrator mob. tel. +381 69/18-68-431 email: e1.e398(a)gmail.com

kamailio's Makefile system : Enabling CFLAGS/LDFLAGS for udp_server.c

by aft

Hi, I'm doing some experimentation on kamailio's udp_server.c. Now i need libpcre for that. So i first thought if i enable the regex module, the CFLAGS/LDFLAGS would be available from udp_server.c. But it turns out it doesn't build(doesn't *link* to be more precise). Kamailio's build system is pretty unfamiliar for me. Although i absolutely hate autotools based build system(I prefer Scons), but i'm pretty familiar with these. But Kamailio's build system is pretty much cryptic for me(Is it based on CMake?). There is a page on devel wiki for kamailio's build system. it turns out i can do stuff like : make cfg prefix=/opt/kamailio \ SCTP=1 \ CC_EXTRA_OPTS=-I/usr/gnu/include \ group_include="standard postgres presence" \ include_modules="snmpstats lcr tls" So there might be a LD_EXTRA_OPTS or stuff like that. Which than would be defined (I guess) globally so the core c files(like udp_server.c) would be able to use that. One way i guess would be to sharpen my egrep and find that variable name. But it all feels a bit hacky. As i have already included regex module, there should be a way to reuse the CFLAGS/LDFLAGS for that module for core files like udp_server.c. Cheers Arif
