[Users] check if transaction exists

[Atle Samuelsen]

Hm, this should be possible to impliment tough..

and, you could even prototype it with the gflags module..

if you do something like: 

route[2]{
   if(uri=~"sip:somenumber at yourdomain.com"){
      if(is_gflag(1){
         sl_send_reply("486","Busy Here");
         break;
      }else{
         set_gflag(1);
         t_on_reply(1);
     };
   };
};

onreply_route[1]{
   if(is_gflag(1) && status == "200"){
      reset_gflag(1);
   };
}
       
I haven't tested it so this is just a idea.. but you could proberbly
extend the gflags module to do somethin glike this only more flexible..
since this is only for one user..
