Actually, it does control it; it uses the Linux routing map to select which
address it uses as its source address.  There has been a request for
some time to allow Asterisk to reply on the same address on which it
received packets, but I don't know that there's been any successful
patch so far.  You're certainly welcome to add your efforts to getting
Asterisk to do that, though.
