 i am trying to access two items via the routing file:  a.) number of
 registered users.   b.) number of active TLS connections.

 I am not pushing the registrations to the database.  usrloc is stored
 in memory.

 any ideas?

[Julien Chavanton]

I see, never done it, but mayne this article can help

http://blog.miconda.eu/2014/12/kamailio-42-tips-12-execute-rpc.html

The parameter has to be a valid full JSON-RPC document. It can be a dynamic
string with variables. The result of the command can be accessed via
$jsonrpl(key) pseudo variables.

Re: [SR-Users] count of registered users or count of tls connections

[Karthik Srinivasan]

Hi Julien,

The routing file i am referring to is the kamailio.cfg configuration file.

I am trying to find a way to access this information within that file.

Thanks,

Karthik

Re: [SR-Users] Anybody using 2 instances with topos communicating with each other?

[Daniel-Constantin Mierla]

Hello,

only spirals cannot be handled by topos due to its initial design (some
things needs to be changed for it), so the case you present should work.

>From the excerpts you present, there is an unexpected Record-Route with
the proxy address in the 200ok towards endpoint. Is it so or just a
mistake in what you pasted here? Because there should be no record-route
with proxy address if proxy does topos.

Cheers,
Daniel

Hi Karthik,

You can retrieve this information using kamcmd

kamcmd stats.get_statistics all | grep usrloc
kamcmd tls.info

Not sure what you meant by "via the routing file"

sorry, i hit the send key a bit too quickly.

i am trying to access two items via the routing file:  a.) number of
registered users.   b.) number of active TLS connections.

I am not pushing the registrations to the database.  usrloc is stored in

Virtualisation can/will add some jitter, but if you configure your setup 
correctly it will work fine for normal phone calls [*]. For example in VMware 
there is something caller NIC interrupt coalescing. AFAIK this is enable by 
default but introduces latency for RTP streams.

But have bare hardware with a rtpproxy will perform better, without any tuning 
a recent machine relayed 900Mbit/s (simulated RTP packets) with ease, running 
vmware a single cpu guest instance was limited to about 40Mbit/s, 2 CPUs in the 
guest topped out at  about 90Mbit/s before jitter and eventual loss occured 
(with coalescing disabled).

*: jitter introduced by rtpengine is negligible compared to the jitter 
introduced by the endpoints themselves (either devices or network setup).

Hi

Are you asking if RTP proxy can work in some other node
than the same where Kamailio SIP proxy instance is running?

If so, answer to that is yes. See rtpproxy module parameter rtpproxy_sock:
http://kamailio.org/docs/modules/5.1.x/modules/rtpproxy.html#rtpproxy.p.rtpproxy_sock

With that parameter you can set RTP proxy in HW and still have SIP proxy in VM.


If on the other hand you are asking about resource management to gain
better jitter and such in virtual environment, then I have no clue.

Hope this helps

[SR-Users] Link problem between kamailio and MariaDB

[Ginhoux, Patrick]

Hi,

 

At the moment, I'm trying to replace MySQL by MariaDB on my Kamailio server
(5.0.1) . In  previous post I have been told that Kamailio supports MariaDB
and there is no special module to load.

 

This work is done on a new server running RHEL 7.4 and MariaDB 10.2.14 that
is installed under /opt/mysql/na/10.2.14 folder.

 

I encounter different problem:

 

-  Without changing anything in the kamailio script, kamailio failed
to find the libmysqlclient.so.18 library.

-  So I thought that I could get rid of the above error by changing
the MODULEPATH in the Kamailio-local.cfg as follows :

MODULEPATH="/usr/lib64/kamailio/modules/:/opt/mysql/na/10.2.14/lib64/"

But with this, I get 2 problem:

The kamailio.log that was written in a /opt/log/Kamailio folder is no longer
updated.

I can only find the errors in the /var/log/messages file:

May 23 11:19:19 vm-siprouter74 systemd: Starting SYSV: Kamailio is a fast,
reliable and flexible SIP Server

May 23 11:19:19 vm-siprouter74 kamailio: Not starting : invalid

To work around the problem we have created 2 symbol links:

<<< ln -s /opt/mysql/na/10.2.14/lib64/libmysqlclient.so.18.0.0
/usr/lib64/libmysqlclient.so.18 >>> the libmysqlclient error

<<< ln -s /myqdata/mysiprdb/data/my.cnf /etc/my.cnf >>> to fix the issue to
open the db

 

It seems that kamailio is always looking for the my.cnf in the /etc/
directory.

 

My concern are to share this job with people who have much more experience
with Kamailio.

 

I would like to know 

-  If the different workaround (ln) makes sense to you or is there
better change to do

-  How to explain the logging issue when changing the modulepath
variable

-  Is it true that kamailio is always looking for the my.cnf in the
/etc/ directory?

 

Any thoughts are welcome.

 

Thanks in advance.

 

Cordialement.

[SR-Users] SIP Server Hardware or VM ??

[Pinter, Gerd.]

Hallo there,

we are a Broadcasting Network with about 50 Stations and try to establish our 
own SIP Network for high quality Audio over IP with Bitrates of 192-256 kbit 
for transmitting an accurate stereo signal.
Since we encountered problems with connections via mobile Networks we set up 
our SIP Server as RTP Proxy which resolved all those multiple NAT issues. But 
on the other hand we pay for that with a higher jitter rate. The question is, 
if anyone has experience if this issue maybe can be solved by running the Sip 
Server on a standalone hardware plugged into network Port on our Hardware 
Firewall, instead of a virtual Machine running on VM with virtual switches and 
so on. The current SIP Server has a Public IP Address, but all the Traffic runs 
thru Firewall, VPN, Hardware Switches and Virtual Switches. What you think?

Thanks a Lot


Nice regards
Gerhard Pinter

Hello,

the myself condition doesn't go into parameters matching apart of transport.

Likely this condition fails because the device is using its own local IP
in From header and R-URI instead of server ip or server domain.

Can be also when the device uses anonymous in From header and dials an
external domain.

Cheers,
Daniel

Greetings,

I'm doing some work with the AUTH routes and modules, and sometimes i get a
"403 Not relaying" answer when the INVITE has a parameter in the R-URI.
That parameter was not included in the REGISTER.

I think it's this part of the code that throws this reply :

# if caller is not local subscriber, then check if it calls
# a local destination, otherwise deny, not an open relay here
if (from_uri!=myself && uri!=myself) {
sl_send_reply("403","Not relaying");
exit;
}

Does a different or new parameter in the R-URI trigger the "uri!=myself" ?
if so, can I set it up to check R-URI but not check the parameters?

Thanks
