Austin,
That is strange, because I am using similar setup successfully. Actually
I don't know if it counts the calls that are being established, I didn't
care for it.
While looking through the docs:
http://kamailio.org/docs/modules/3.1.x/modules_k/dialog.html#id2524304
the following note caught my eye:
IMPORTANT: Users of this function should make sure that the dialog
created is further processed statefully. Specifically, if a stateless
response is sent out after dlg_manage() is called, the dialog cannot be
handled properly. So make sure that a transaction exists or create it
explicitly using the tm module. This is a shortcoming of the current
implementation that may be resolved in a future version hopefully.
Could it be that you are forwarding the INVITE statelessly?
Regards,
Andrew

Thanks Andrew
I added profile_with_value module parameter and with that I am able to
overcome this error.
My code looks as below.
dlg_manage();
if (is_method("INVITE")) {
if (!has_totag()) {
#$var(SIZE) = 0;
get_profile_size("caller", "$fu",
"$var(SIZE)");
xlog("Number of calls present now is
$var(SIZE)\n");
if( $var(SIZE) > MAX_NUMBER_OF_CALLS ) {
sl_send_reply("503", "Simultaneous calls
limit reached");
xlog("Rejected calls with 503
Simultaneous calls limit reached\n");
exit;
}
else {
xlog("Allowed call. Looks max calls
limit not reached. Calls= $var(SIZE)\n");
}
set_dlg_profile("caller","$fu");
}
}
Whole purpose is to limit number of active calls at any point of time.
$var(SIZE) gives the number of calls are being established, but not the
number of calls are already established.
So if I am making multiple calls at a point of time, it is blocking
call attempts beyond limit. But after all call setup complete, again
$var(SIZE) becomes zero and allows new calls.
Has anybody done this (limiting number of calls at any point of time).
If so can you please share the configuration file changes.
To get $var(SIZE) working properly, do I need to enable MySql, please
advice.

Austin
