Default 3.3 config and dispatcher
by Paul Belanger 29 Jan '13

29 Jan '13

Greetings List, First post of many. I've managed to get up a running a very simple VoIP network with Kamailio as the core, and asterisk on the edge. Most of this has been accomplished using the default kamailio.cfg file shipped in 3.3. For my next adventure, I'd like to start using the dispatch module to route calls from Kamailio to asterisk, however having some trouble getting my syntax correct. I was hoping somebody could point me to an existing post / URL describing what I was asking, if it is based on the default configuration file, the better. I should note, if I have Asterisk register to kamailio, I can route calls fine however, I believe the dispatcher is the better way to do this. -- Paul Belanger | PolyBeacon, Inc.

Major problem with setup NAT + MULTIDOMAIN
by Rumen Mihailov 29 Jan '13

29 Jan '13

Hi guys, I've baning my head for the last 6 7 days with something that have to be universally simple but obviously for me it is not, so please do help. I have the following setup. xx.xx.xx.xx (real IP 1:1 NAT) -> 10.2.47.201 Kamailio listens on 10.2.47.201 I have setup a domain xxx.itradebg.com and I've made the appropriate records in the DNS. I have inserted the domain xxx.itradebg.com in the domain table in the database and kamctl domain show shows the correct thing. Now when I try to register 999(a)xxx.itradebg.com I get Request timed out I have this in my config: if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "sip", "1")) { auth_challenge("$fd", "0"); exit; } } if (from_uri!=myself && uri!=myself) { if(lookup_domain("$fd", "@from.uri.host")){ xlog("LOCAL DOMAIN -> REGISTER"); exit; } else{ xlog("L_WARN","FROM NOT LOCAL"); sl_send_reply("403","Sorry mate not relaying"); exit; } } By the time of writing this I realised that this should be all rewritten to this only, as the second check is useless: if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "sip", "1")) { auth_challenge("$fd", "0"); exit; } } However I get 401 Unauthorized. The previous setup was giving me 408 - Request Timed out... I am pretty sure I have the passwords correct. What I cannot understand is why authentication fails ?! Also, how do I set kamailio to print debug output ? debug=9 log_stderror=no This is what I have in the .conf file. /var/log/messages seems to only have what I have printed with xlog... (think) I am really out of ideas... perhaps I need some sleep. Anyway any input is helpful guys. Thanks, Rumen http://itradebg.com

Error searching $keepalive.socket pvar in NAT Traversal module
by vito 28 Jan '13

28 Jan '13

Hello, I started to use Kamailio few months ago. Maybe this is a stupid issue but I can´t start Kamailio with NAT TRAVERSAL module and $keepalive.socket pseudo-variable. My script configuration is the default template adding this lines (extracted from nat traversal doc): ... loadmodule "nat_traversal.so" ... ... $fs = $keepalive.socket($du); ... I have this error: -e 0(17455) ERROR: <core> [pvapi.c:501]: error searching pvar "keepalive" 0(17455) ERROR: <core> [pvapi.c:705]: wrong char [e/101] in [$keepalive] at [9 (0)] 0(17455) : <core> [cfg.y:3330]: parse error in config file /etc/kamailio/kamailio.cfg, line 410, column 8-17: unknown script pseudo variable $keepalive ERROR: bad config file (1 errors) I tried in this environments: Ubuntu 10.04.4 LTS x86_64 Kamailio 3.3.3+git20130128+lucid1 Ubuntu 10.04.4 LTS i686 Kamailio 3.0.4+lucid1 Ubuntu 12.04.1 LTS x86_64 Kamailio 3.3.2+precise1 All packages instaled from deb repositories (http://deb.kamailio.org/) I think there are problem parsing "$keepalive.socket" pseudovariable, because Kamailio doesn´t scape this character "." and it doesn´t recognise the pseudovar. Does anyone have this problem? Regards

TLS certificate chain Android verification
by Nord7 28 Jan '13

28 Jan '13

Hello all. Our company buy Thawte SSL Web server certificate. I'm enabled in Kamailio 3.3 TLS support and configured him. Adding to "myhost.pem" certificate, two "intermediate" certificates (like in chain) "cat myhost.pem SSL_SecondaryCA.pem SSL_PrimaryCA.pem > chain-cert.pem". Remark: I use this chain on apache2. And Android trusted to this certificate chain. After this i use chain-cert.pem with KAMAILIO 3.3 and SIP client "BRIA Android". "Bria Android" says certificate is not trusted. Next step "BRIA IPHONE" and certificate chain works (trusted)! BRIA support says me - BRIA don't trusts certificate if system don't trusts. Why Android don't trusts to my chain-certificates with KAMAILIO? If his trust to same certificate with Apache? I'm understand this is not Kamailio problem, but maybe any one who have expirience in this problem help me? I know about bouncycastle, but this is not best decision for me. Maybe something else can help? I tryed this with Android 2.3.7, 4.0, 4.1. Best regards Kirill.

event_route for pre-dialog start
by Mino Haluz 28 Jan '13

28 Jan '13

Hi, I think that it is more than likely not implemented, but is there any event-route that is triggered just before event_route[dialog:start] ? I need to check some security flags before the dialog is created. But it is too early too check them in relay route.. Mino

Is kamailio creating multiple connections to db?
by Mino Haluz 28 Jan '13

28 Jan '13

Hi, I made some DB test on our HA cluster, and I got that for 1 process I have 1000 queries/sec and for 11 processes 3000 queries/sec. That's why I would to ask if every kamailio process that is spawned has its own database connection or queries are put in the queue and executed by some main process ? I would like to know this, so that I could assess maximum call count/sec that db can handle. Thank you, Mino

Generating logging based on SIP messages
by Grant Bagdasarian 28 Jan '13

28 Jan '13

Hello, A while ago I came across the siptrace and sipcapture modules and thought this would be a good way to generate logging out of all the SIP messages that are passed through Kamailio and stored in the siptrace/sipcapture table. My idea was to extract certain values from SIP messages and store these in our database. Also each SIP Request or Response would be mapped to a certain status so we would be able to monitor which call is in which state. I still have a lot of work to do to think this all out, since it's still only an idea. I'm just wondering if anyone could give me some pointers into what to keep in mind when doing this. Regards, Grant

Pseudo variable to get instance in the contact....
by Krishna Kurapati 28 Jan '13

28 Jan '13

Hi, I added in my local branch "$ct.inst" pseudo variable to retrieve instance. Since instance could be an important attribute to make routing decisions, having quick access to it in the message may be useful. Anyone else need this functionality? Krish Kura

by Kasper Hämäläinen 28 Jan '13

28 Jan '13

hi guys, hope u got time to help me. Im first timer testing VoIP and SIP. I created account to ur iptel.org site. I downloaded "Jitsi"-software. First when I opened it, I login with my username and password. Then I go to "add new account", give same login username and password, but Jitsi says that my password is wrong..wtf. And I installed Media5-Fone to my iPhone 4S. When adding SIP-account it's says again that I got wrong password. And YES, I didn't mistype it. Thanks - Kasper
