More likely is that the phones on the LAN are SIP and the boxes on the 
WAN are talking IAX, since that seems to make the most sense to me.

It's not always so sneaky... imagine that I'm a VoIP provider targeting 
homes and small business.  I'm best to buy minutes in bulk from AT&T 
and/or MCI or any carrier who can offer super-cheap rates in bulk.  
These carriers don't sell VoIP to home users, they sell it to people 
like me.  I still don't really want my users or competition know where I 
buy my minutes from, nonetheless.  And AT&T doesn't really want a direct 
connection to the home user.  So it works out that I am the logical 
middle-man, especially if I can trunk calls within a few hops of the 
user (like if I'm also their DSL provider as well) to save everybody 
bandwidth.

Most significantly, this hierarchal paradigm is the most familiar to 
telcos and telephone people in general.
