Use of variables for force_send_socket
by Jöran Vinzens 11 Apr '17

11 Apr '17

Hi all, i try to re-arrange my config and i try to use a variable declared in modparam pv such like: modparam("pv", "varset", "externalip=s:1.2.3.4") and use it as: force_send_socket($var(externalip)); unfortunately the kamailio does not start with this configuration and telling me bad config file like: line 109, column 36: bad argument, [proto:]host[:port] expected it seems the force_send_socket is not able to get variable. Is there any other way to have static content defined and put across the config? Reason for the question is the possibility to use ansible as deployment tool. I set all the variables i need in a separate file and include it. This file contains the entire modconfig and global vars section to adapt this part to every single machine individually. This does not work if i need to put "constant" variables on different places in my config. If anybody has ever made this, could you please help me, or give any suggestions? Many thanks!

Notice: work on mailing lists server
by Daniel-Constantin Mierla 11 Apr '17

11 Apr '17

Hello, be aware that today I plan to do some maintenance on the mailing lists server, including the shifting to the lists.kamailio.org as primary domain. I expect not to have any relevant downtime, but one never knows. Maybe the archive won't be available for short time due to changes needs to be done to the web server after mailing lists server is upgraded. I will sent another notification when everything is finished.

Authentication on Kamailio with MySQL
by Nicolas Pace 10 Apr '17

10 Apr '17

Hi everyone, I'm having some trouble setting up a simple Kamailio installation with user authentication. I've installed a kamailio (4.3.4) base install on an ubuntu server 16.04 (x86/64) on virtualbox, and added this lines at the beginning of the file: ``` #!KAMAILIO #! define WITH_MYSQL #! define WITH_AUTH #! define WITH_USRLOCDB ``` Also configured the db name, host, user and pass for RO and RW and run `kamdbctl create`. Everything I do was following this tutorial: http://www.kamailio.org/wiki/tutorials/getting-started/main Based on what the tutorial says, I should have a server that only allows users that have been authenticated against the DB. The thing is that now Kamailio allows me to access, no matter what credentials I gave him (replies 200 OK to my REGISTER requests, and whows the user on the `kamctl monitor` view). I've added to this gist: * My current kamailio config * the kamailio grepped syslog * the pjsua output from when I register with an unexistent user https://gist.github.com/nicopace/9d44bf813fe309df69ff4cd0affe8324 I've already checked out some of the wiki documentation, namely: * http://www.kamailio.org/wiki/tutorials/auth/auth_db * http://www.kamailio.org/wiki/tutorials/getting-started/main Am I missing something? Thanks

Introduction
by Nicolas Pace 10 Apr '17

10 Apr '17

Hi Everyone! I just wanted to introduce myself, before blasting the list with questions (just kidding!). My name is Nicolás Pace, I'm a Community Networks advocate from Argentina. I'm working on a community project for Rhizomatica [0], which is an amazing organization that promotes Community Cellular Networks for underserved communities in Latin America (mainly mexican's first nations but also in Nicaragua, Colombia nad Brazil). We are working on a mobile app to connect the Community Cellular Networks (that uses 2G Cellular Networks) with the rest of the world via SIP, and we are considering using Kamailio for this. The project has been using FreeSwitch for some time and now we are thinking about using Kamailio on the cloud side, and intengrate them via SIP. On a not so distant future, if the Kamailio experience goes well, we are thinking on moving everything to Kamailio, as it seems to be much more simple and effective. For now we expect to do a prototype to connect this communities with their relatives via SMS (on the Cellular side) with SIP SIMPLE Messages (on the 'cloud' side). Awesome to meet you all, and hope to be collaborating with this community! Regards, [0] https://www.rhizomatica.org/

INFO: Shifting mailing lists to kamailio.org domain
by Daniel-Constantin Mierla 10 Apr '17

10 Apr '17

Hello, I think it is time to migrate the mailing lists under kamailio.org domain, respectively use lists.kamailio.org. The lists.sip-router.org will still work, but lists.kamailio.org is intended to become the primary domain for mailing lists. The sip-router.org was the quick solution for integrating Kamailio and SER in one project back in 2008, when kamailio.org and iptel.org still needed to be operated for a while as independent projects. For few years now, Kamailio is the only project name that is used out there and it will make operating everything a bit smoother, more coherent and also avoid eventual confusions for people new into the project. As a matter of fact, we even had a small incident few weeks ago -- due to split management of sip-router.org and DNS registration expire notifications going to an email address on a different server than kamailio.org, the domain was expired for few hours (although it was kept on hold by registrar) and mailing lists started to be unavailable. Fortunately that was discovered and fixed in time. The names will stay the same sr-users and sr-dev, just primary domain will be using kamailio.org (which should 'hopefully' work even now, as this email was addressed with mixed sr-dev(a)lists.sip-router.org and sr-users(a)lists.kamailio.org). If anyone has different opinions or suggestions, let's discuss them!

Transaction Lookup Failing
by Colin Morelli 10 Apr '17

10 Apr '17

Hey all, Trying to debug an issue with canceling an invite. I have two different types of clients. On one client, canceling an invite works correctly. With the other client, it t_check_trans fails. Both clients show the same request/responses: On Client A: -> INVITE <- 183 -> PRACK <- 200 -> UPDATE (from successful STUN binding) <- 200 -> CANCEL <- 200 On Client B: -> INVITE <- 183 -> PRACK <- 200 -> UPDATE (from successful STUN binding) <- 200 -> CANCEL <- 481 (this is sent from my kamailio script when t_check_trans fails) I can't see much that's different between the leading requests/responses of each. They seem to be virtually identical (with the exception of IP addresses and tag values, of course). This makes sense, since they're both based on PJSIP (albeit different versions of PJSIP, but not off by much) Is there anything in particular I should be looking out for that might be obvious? I could provide more detailed logs and traces if required. Best, Colin

"kamdbctl create" failed
by Tim Makarios 10 Apr '17

10 Apr '17

Hi, Following http://kamailio.org/docs/tutorials/devel/kamailio-install-guide-deb/ I got to the step where I had to run kamdbctl create Unfortunately, this failed, with the following output: > INFO: test server charset > INFO: creating database kamailio ... > INFO: granting privileges to database kamailio ... > INFO: creating standard tables into kamailio ... > ERROR 1101 (42000) at line 2: BLOB/TEXT column 'body' can't have a default value > ERROR: Creating core tables failed at msilo! Searching for this error turned up http://tinyurl.com/lovr4aq , but the link in the answer is broken, and it doesn't appear that STRICT_TRANS_TABLES is relevant to my version of MySQL [1], which is 5.5.54 (running on Trisquel 7, which is based on Ubuntu Trusty). Has anyone else encountered and overcome this problem, or does anyone have any ideas about how I might proceed? Tim <>< [1] http://tinyurl.com/zmnc75c

Carrier Route Module
by Tyler Preder 10 Apr '17

10 Apr '17

I am new to Kamailio. I've got the Carrier Route module up and running, but I'd like to match on scan_prefix length and not just the scan_prefix digits. Stated a little differently, I would like to define the scan_prefix and how many digits to expect after the scan_prefix. I am hoping that wildcards are supported in the scan_prefix field or is there another way to do this? Thanks, Tyler

Using $var inside textops function
by Olli Attila 07 Apr '17

07 Apr '17

Hello, Is it possible to use variables inside a textops search_hf function? I am trying to compare variable content against From header content and return true or false. I tried the following statement but with no luck: search_hf("From", "$var(MYVARIABLE)", "f") { ... } If this cannot be done, any suggestions on how to achieve this kind of comparsion? The variable content is pulled out from a htable entry. Cheers, --Olli

Hey Daniel, Many thanks again for premium support as always ;). Will get back to them since I understand Kamailio is RFC compatible on this one. Have a good one! DanB
