By the way, there is a reason for this. It ensures that there is  
traffic (initiated by the client) often
enough to keep the 'connection' in a NATing firewall's map of ports.  
This means that a
'new' call (ie incoming) message from asterisk to the client will be  
seen by the firewall as part of that
'recent' conversation and allowed through (and correctly forwarded).

So unless you _know_ the timeouts on all the firewalls involved, I'd  
play safe and change the
firefly end.
