Ok, I understand the problem. And what about Message flags?


route {
   setflag(3);
   if(method=="INVITE")
       m_dump();
   if(isflagset(3))
   {
         # Is it executed for the incoming INVITE?      <-- A
   } 
}


local_route {
   if(isflagset(3))
   {
         # Is it executed for the dummped MESSAGE?  <-- B
   } 
}


In this case (using message flags instead of script flags) is the behaviour 
the expected? This is:
- A is executed for the incoming INVITE.
- B is NOT executed for the dummped MESSAGE.


Thanks a lot for your explanation.
