You should use one setflag when the call starts (on INVITE) and one when the 
call ends (BYE or CANCEL), so I suggest

- remove setflag on top of route, then add 

if ((method=="BYE" || method=="CANCEL") && !(uri=~"^sip:833*@WHATEVER")) { 
   setflag(1);
}

between record route and loose route sections (as you record_route your calls, 
BYEs or CANCELs are relayed in loose_route section, so you need to set acc 
flag before relaying BYE in loose_route)

- you can safely remove || method=="BYE" || method=="CANCEL" and keep only 
method=="INVITE" in uri==myself section (remember BYE and CANCEL hit 
loose_route!), and add uri check as above to the following setflag

So your routing logic now should work like this

INVITE -->  call for 833* ? --> if not: flag 1 (call started) --> call relayed 
--> BYE --> call for 833*? --> if not: flag 1 (call ended) --> SIP session 
closed


ciao
