[SR-Users] Handling quota/call limits - kamailio 1.5

[Graham Wooden]

Ok, I expanded on that example and got this working; for the most part.

What is the best way to get that MAX_NUMBER_OF_CALLS to be a value that is
set per subscriber?  Or keep my quota table and just pull the value from
there?

modparam("dialog", "profiles_with_value", "callquota")
.
.
.
          if (is_method("INVITE")) {
                $var(SIZE) = 0;
                get_profile_size("callquota", "$rU", "$var(SIZE)");
                if( $var(SIZE) >= MAX_NUMBER_OF_CALLS ){
                        sl_send_reply("503", "Simultaneous calls limit
reached");
                        exit;
                }
                set_dlg_profile("callquota","$rU");

                if (get_profile_size("callquota","$var(SIZE)")) {
                        xlog("DEBUG: there are $var(SIZE) total calls for
$rU\n");
                }
