Kamailio 5.0 - Scripted DB Migrations
by Tim Chubb 08 Mar '16

08 Mar '16

As a suggestion for 5.0 having a scripted DB migration system would make upgrading much easier. Something like what Asterisk now uses (Alembic https://pypi.python.org/pypi/alembic) would be ideal, as it works in a DB agnostic manner and you would just have to ensure that there is a driver for the DB you wish to use. That way you would just update the definition script and select the target when you run the updater, and would allow kamailio a greater choice in backing DB's as once the script is written assuming a driver is available for you RDBMS the schema would be successfully ported. This would do away with maintaining separate MySQL, Postgres, Oracle, MSSQL scripts as well. The only issue I can think with a system like this is in the situation where hardcoded SQL strings are in the source and use a RDBMS specific function as that could cause some "fun" in debugging...

question about dlg_var
by 张顺通 08 Mar '16

08 Mar '16

I want to distingguish 200 OK is for INVITE or reINVITE。 so I do this: request_route { if (is_method("INVITE") && !has_totag()) { $dlg_var(is_init_invite) = "1"; } } onreply_route { xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); if (is_method("INVITE") && t_check_status("200") && $dlg_var(is_init_invite) == "1") { # do somting $dlg_var(is_init_invite) = "0"; } xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); } What I confuse is： When I recive 100 Trying LOG is [100 - Trying][is_init_invite:0] [100 - Trying][is_init_invite:1] why is_init_invite is 0?

Kamailio design that needs one b2bua
by anthony gonzalez 08 Mar '16

08 Mar '16

Hello there, I'm designing and implementing a kamailio solution for sip routing between several softswitch based on prefixes. IIn this setup i will need an b2bua in order to do topology hiding and also to make transparent the call transfer between phones registered in kamailio and softswitches(that doesn't support very well REFER messages). I was searching what solution should I use and I found 3 opensource solutions that for me seems to be acceptable: Sems. Freeswitch. Opensips with module b2bua. Based on your experience and contemplating the stability, performance and support, what is the solution that you advice me ? Thank you for you time. Anthony

Kamailio 5.0 - pseudo variable name cleanup
by Sven Neuhaus 07 Mar '16

07 Mar '16

Hi, a suggestion for Kamailio 5.0 is to get rid of the cryptic, case sensitive pseudo-variable names. Instead we replace them with descriptive names like the ones already provided by the TLS module. The current pseudo variables are a constant nuisance unless you deal with Kamailio every day and know them all by heart. They are an unnecessary barrier for new users learning Kamailio and force you to refer to the documentation more often than necessary. Ideally there would be a script to replace old variable names in configuration files with the new ones to make the transition less painful. -Sven

How to get Authorization Attributes
by Matthew Harrold 07 Mar '16

07 Mar '16

Hi All, I am trying to get attributes from the Proxy-Authenticate WWW-Authenticate and Authorization headers, namely username, realm, uri, nonce, and response, I can see some of these are already presented as psuedo-variables, however nonce and response are not. What's the most efficient way to obtain these headers? I'm currently using a regex, but there must be a more efficient method. Thanks for your help, Matthew

Re: [SR-Users] KAMAILIO Installation Problem
by Ed Todd 05 Mar '16

05 Mar '16

KAMAILIO Installation Problem Fred: re confusion. A few more details. Site 1 is a development site. The project in question is VoIP, using ANTISIP. A Windows server application is monitoring activities and carrying out local functions via IPhones. It has a LAN with static IPs for: · Windows 10 PC used for development · Windows 10 laptop, used for testing · MACBOOK, used for IPhone development · ‘Other PC’, recently converted to Linux + KAMailIO, using the binaries installation route rather than the source code route. It has a Comcast Modem/Router, Cisco DPC3941B Site 2 is a business site, which demonstrates the application using its own Windows PC and IPhones. It does not have any static IPs. Each site uses IPhones as the user interface of this application, via cell or WIFI. Both sites can communicate via SIP.ANTISIP.COM Site 1 can communicate with site 1 KAMAILIO but site 2 cannot: timeouts occur. I just installed what seems like a standard package: · Debian 32 or 64 bit graphical · Apt-get install git gcc make flex bison mysql-server kamailio-mysql-modules kamailio-tls-modules kamailio Should be OK so far apart from the .COM name of the Linux box. I then updated files as described earlier and the problems start. Apart from changing a few constants, I have not altered any script, I am just using the standard one shipped in the package above. I’ve had to guess how to tell KAMailIO about the static IP.

KAMAILIO Installation Problem
by Ed Todd 05 Mar '16

05 Mar '16

I have a local area network with: · A Windows PC with a VOIP application · A Linux PC with KAMailIO There is also a remote Windows PC with the same VOIP application. There is also an IPhone VOIP application that communicates with the Windows PC application. All communications use the same KAMailIO system. The IPhone application communicates with the PC on the local network. It times out trying to communicate. I have tried a URL and a static IP address for SIP_DOMAIN, neither succeeds. Here are some extracts from the log (ignore timestamp gap, several calls were attempted). I think the problem is that the reply to the PC is being sent to 192.168.1.12 instead of 92.13.147.87.
