Hello,
I have 2 kam instances using one shared database and both kam servers
running the same routing logic code. Kamailio servers are configured to use
the same database as dialog backend.
I am limiting the concurrent dialogs in the following way but it seems that
kamailio is using its own memory to read profile size rather than the db.
Second kam is not aware of the dialog profiles that the first kam wrote to
the shared db. Is there a way to get multiple kam instances to read profile
size from the same database when calling the get_profile_size function?
modparam("dialog", "profiles_with_value", "concurrent_calls")
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "db_url", DBURL)
modparam("dialog", "db_mode", 1)
route[LIMIT_CALLS] {
if (!dlg_isflagset("1")) { # $td – gateways, $fu - user
if (get_profile_size("concurrent_calls", "$fu", "$avp(calls)")) {
if ($avp(calls) >= 3) {
xlog("L_INFO", "Concurrent calls $fu at limit");
send_reply("503", "Calls limit reached"); exit;
} else {
dlg_manage(); dlg_setflag("1");
set_dlg_profile("concurrent_calls", "$fu");
}
}
}
}
Cheers,
Olli
