[SR-Users] Kamctl stats

[Alexandru Covalschi]

Hello list,

Where can I found any information to completely understand what do values 
returned by 'kamctl stats' represent?

Cheers,
Alex

[SR-Users] tcp_set_connection_lifetime - does not close the connection immediately

[Andy]

I am calling tcp_set_connection_lifetime(conid, 1),
which I understand is one sec after now,

but I see it taking upto 60 secs to kill the connection,
is there any other timer which has a larger interval which might affect
this.

[SR-Users] Is there a way to detect inactive MSRP chat sessions without using SIP session timers

[Pranathi Venkatayogi]

Hi,

  I am using MSRP feature of Blink client. I want to track when the chat starts 
and ends so I can free up server resources.

  Apparently Blink client does not send BYE when MSRP chat window closes. It 
does not support SIP session timers even.



  So potential use of SIP session timers (sst and dialog modules) is ruled out.



  Only possible way is to track every message that goes through the server and 
keep the session alive.

  If no message comes within “expiry time period”, server can send “bye” to all 
parties and tear up the session.



  Can you please comment if there are other approaches to solve this problem?

  If not, are they any modules that will help me implement the above approach 
easily?



Thanks

Pranathi

Hello,

if you want to fetch them for config usage is ok, otherwise m_dump() is
still better, because it takes care of removing delivered messages, etc...

Re: [SR-Users] Send SIP Info within a dialog using $uac_req(method)="INFO"

[Daniel-Constantin Mierla]

Hello,


just to point out a trick that sometime can save backslash escaping of
quotes. One can start the function parameters with single quote, then
double quotes don't need to be escaped. Other blackslashes need to be
escaped and it this case you need more because you want to propagate
then to the command line.


Cheers,
Daniel

Re: [SR-Users] Possible memory leak in mysql driver

[Daniel-Constantin Mierla]

Working dir can be provided with -w command line parameter. If not set,
the corefile should be generated in / or a folder specific for the OS
settings (e.g., macos has /corefiles).

Root is needed because some OSes have restrictions on which app can dump
core files. You can try with a normal user and if not working, then
using root might be the solution.

Cheers,
Daniel

Re: [SR-Users] Error message not seen before

[Daniel-Constantin Mierla]

Hello,

maybe the table was not available when you installed first time siremis,
being added in later versions of kamailio.

You can create the table in kamailio database using the script locate in
source tree at:

  - utils/kamctl/mysql/uac-create.sql

Or if you don't use uac module for remote registrations, then you can
disable that option from menu, so nobody else ends up in such error.

Cheers,
Daniel
