Hey Ovidiu, do you have a working config, I'm pretty new to openSER?
The one I'm using at the moment is attached,
Thanks in advance,

Hi Axel,
For each INVITE (not reINVITE) you will need to set the flag specified
via the params. Like this, you will have a dialog per call. Then you
can use your logic to restrict the number of concurrent calls.

Has anyone managed to restrict the number of concurrent calls on an

box?
I'm using openser 1.1.1 and found on the web that this was needed.
I've included the dialog.so and avpops.so modules.
if ( avp_check("$DLG_count", "gt/i:10") ) {
sl_send_reply("403","no more calls accepted");
exit;
}
I'm not sure if I've configured the dialog.so module correctly, the
documentation tells you what each function does, but not what the
parameters
mean (for example the documentation says dlg_flg default value is
"none" and
they give an example of it set to 4 - but what do these values mean?)
Has anyone got this working or does anyone know how I should be
configuring
the dialog.so module?
Thanks,
-Axel
