Re: [Kamailio-Users] Dialog profile size not resetting in 1.4.4.

Greetings,

I've run into an issue with 1.4.4 in which the following appears to be happening, and I'm yet to determine the cause:

The total amount of open inbound calls (dialogs) is tracked with the dialog module by putting them in a global profile. Because of a segfault bug with profiles with "no values," a workaround is used wherein a profile "with" values is created and the hash key is always the same value (i.e. "1"). The dialog tracking flag is 2:

modparam("dialog", "dlg_flag", 2)

And profile looks like this:

modparam("dialog", "profiles_with_value", "globalinbound;specificinbound")

Anyway, inbound INVITEs get handed off to a route (route[1]) that performs some logic like this:

route[1] { # Check if DID is assigned to an account with database # and store value in AVP, along with other values.

   if($avp(S:did_assigned) == "0") {
       sl_send_reply("404", "Not Found");
       exit;
   }

   get_profile_size("specificinbound", "$avp(S:account_id)", 

"$var(a_concurrent_calls)");

   if($var(a_concurrent_calls) >= $avp(S:port_limit)) {
       sl_send_reply("486", "Busy");
       exit;
   }

   setflag(2);   # Track dialog.

   set_dlg_profile("globalinbound", "1");
   set_dlg_profile("specificinbound", "$avp(S:account_id)");

For completeness, I should add here:

# Perform dispatcher election - ds_select_domain().

t_on_reply("1"); t_on_failure("1");

if(!t_relay()) sl_reply_error();

exit;

}
