Mind you, SIREMIS will allow you to modify underlying database tables for 
database-backed modules, and will also expose some management and monitoring 
information.

But it doesn't solve the core problem of getting Kamailio to do what you want 
it to do. You still have to learn to write that. There aren't really any 
shortcuts.

Hello Stefan,

I digged further into this issue and looked to the protocol format in 
utils/pdbt/docs/network_protocol.txt.


One strange thing I noticed:

Kamailio sends a request in version 1 out, this is the default since 
2015 or so.

Kamailio recieves a reply in version 0, it should be version 1 as well.

Do you query with the Kamailio 5.1.x to the pdbt server in version 
4.x? If yes then I suspect this is the problem.




I tried to use the pdb server from kamailio 4.x (because I was sure it 
works) and I also used only the pdb-server on localhost where kamailio 
5.1.2 is running.
But the result is the same, asking with version 1, response with version 
0 and result=0.
How can I check the version of pdb_server to make sure it's up to date 
and should work with kamailio 5.1.2?



The version change in pdbt was done after the release of the 4.3 branch.

Best regards

Henning

Re: [SR-Users] Installing RTPengine on CentOS 7

[Brooks Bridges]

Those are the libraries for ffmpeg and they are not part of the default 
repositories.  The NUX Desktop repo has them: https://li.nux.ro/repos.html

The packages you want from that repo are "ffmpeg" and "ffmpeg-devel"

Subject: [SR-Users] Installing RTPengine on CentOS 7

Hi,

I'm trying to install RTPengine in the same machine as I have Kamailio, running 
CentOS 7, but there are a few dependencies that yum cannot seem to resolve and 
I that cannot find anywhere else.

As soon as I try to build the daemon it produces these errors:

make[1]: Leaving directory `/usr/local/src/rtpengine/daemon'
Failed build with ../lib/fix_frame_channel_layout-01.h
Trying build with ../lib/fix_frame_channel_layout-02.h
make[1]: Entering directory `/usr/local/src/rtpengine/daemon'
rm -f "resample.c"
echo '/ GENERATED FILE /' > "resample.c"
cat ../lib/"resample.c" >> "resample.c"
Package libevent_pthreads was not found in the pkg-config search path.
Perhaps you should add the directory containing `libevent_pthreads.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libevent_pthreads' found
Package libavcodec was not found in the pkg-config search path.
Perhaps you should add the directory containing `libavcodec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavcodec' found
Package libavformat was not found in the pkg-config search path.
Perhaps you should add the directory containing `libavformat.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavformat' found
Package libavutil was not found in the pkg-config search path.
Perhaps you should add the directory containing `libavutil.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavutil' found
Package libswresample was not found in the pkg-config search path.
Perhaps you should add the directory containing `libswresample.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libswresample' found
Package libavfilter was not found in the pkg-config search path.
Perhaps you should add the directory containing `libavfilter.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavfilter' found

So, in the end, at least 'libevent_pthreads','libavcodec', 'libavformat', 
'libavutil', 'libswresample' and 'libavfilter' are missing.

Trying to install them one by one with yum fails because it cannot find these 
packages for CentOs 7.

Can anyone point me to a solution for this?

Thanks,
Francisco.

[shubh diwase]

Just yum search package name,and you will get the current and supportable
version,or search for yum repository updates

Thank you for sharing your insights. Over the past 5 years I stumbled
over your (and other contributors) articles that gave me some food for
thought regarding the use of kamailio and SIP in general, making it
possible for me to build a solid VoIP platform.

I should really go to Kamailio World in the future to buy you all some
nice German beers.

Re: [SR-Users] Textops Regex

[Duarte Rocha]

 You're right, it is application/sdp and the back slash works as escape
character.

However, a new problem came. I'm using this, since someone upstream is
adding \r\n to a part of the body :

replace_body_all("application\/sdp\r\n\r\n", "application/sdp\r\n");

The regex finds the application/sdp just right, but doesn't replace
everything. So, as a final result i get applicationapplication\sdp\r\n. Is
this intended?

Thanks for your help

Re: [SR-Users] centos 7 repo is broken?

[Daniel-Constantin Mierla]

Hello,

The repo is offered and managed by OpenSUSE project. We only have portal
accounts to upload specs and other files used to build the rpms. If the
servers/mirrors are down, we can't do anything from the Kamailio project.
If it persists, then it should reported to OBS site.

Cheers,
Daniel

Hello Tobias,



I see. Regarding further debugging - not sure if this is easy feasible - what 
about just connecting the "debug" kamailio directly to the database without the 
firewall? If you still loosing connections in this setup, I would investigate 
the situation further on your side.



Do you use SSL? There has been a lengthy discussion with a similar issue at:

https://github.com/kamailio/kamailio/issues/406



It could be also something related to a machine with several network interfaces:

https://lists.kamailio.org/pipermail/sr-users/2015-October/090266.html



If this path does not bring you closer to a solution, I would try the debug 
kamailio against a different (maybe fresh installed) isolated database. Then I 
would try move the debug kamailio on a different (maybe fresh installed) 
machine. Basically just changing one thing at a time until the issue stops.



Another option would be to capture the TCP traffic of the debug kamailio 
against the database and look for strange things in the wireshark.



Best regards,



Henning

[SR-Users] rtpproxy_stream2uac

[Narasimhaiah, Vinod Maralenahalli]

Hi,
I am trying to configure kamailio to play early media and i am using
rtpproxy_stream2uac(), but the audio file plays only after the call is
connected.

How to use rtpproxy_stream2uac() to play only the early media.




Thank you
vinod.M.N
