Thanks !
Ok, but to be more specific, are there any general recommendations on question 
like: Should the PBX drop the packets with wrong payload and let the 
call/session continue or should the PBX also drop the entire call ?

There's no real definition of "clearly belongs to".  If a packet arrives at a 
port, it is processed according to the usage that has been negotiated for that 
port.
