Hi all,

I am writing to you again after a long time for a strange issue in my 
Opensips 1.11 routing logic.

I have implemented a per-user call limit and i have to compare current 
call value with max calls allowed:

main() {
	if (is_method("INVITE")) {
             if (!create_dialog()) {
                 send_reply("500","Internal Server Error");

             set_dlg_profile("call", "$rU"); # caller
             set_dlg_profile("call", "$fU"); # called

             get_profile_size("call", "$rU", "$var(calls)"); # What's the call limit for $rU?

             if(avp_db_load("$ru/username","$avp(maxcalls)")) {
                 if($var(calls)>$avp(maxcalls)) {
                     xlog("L_INFO","$ci - User $rU has $var(calls) calls (max $avp(maxcalls) calls): BUSY\n");
                     sl_send_reply("486", "Busy: try later");
                 } else {
                     xlog("L_INFO","$ci - User $rU has $var(calls) calls (max $avp(maxcalls) calls): ALLOW\n");
             } else {
                 xlog("L_INFO","$ci - User $rU has $var(calls) calls. NO LIMIT HERE\n");
             # -->

Seems that there's a problem with "if($var(calls)>$avp(maxcalls))" 
because in logs i got:

User XXXX has 2 calls (max 10 calls): BUSY
User XXXX has 1 calls (max 10 calls): ALLOW

Any hints or suggestion?

Thanks for your help.
