My sugestion would be if you have more than a couple of phones behind 
this one firewall, why wouldn't you run a very basic * server to coonect 
all those SIP phones to and then IAX to the external * server. This does 
not have as much issues with the firewall and then you could possibly 
take advantage of some of the bandwidth saving features in IAX for your 
connection.

Just a thought and I don't know how that will work with your operation 
but that is what I thought might be an Option.
