[asterisk-users] S101I (IAX) limitation

[Joseph]

That little Digium adapter S101I is a nice and compact (good for travel)
but has a serious limitation, it doesn't support bridging.
If I have four/five of these units registered to my asterisk server
(over the Internet) and with standard DSL or Cable connection all for of
them connected and in use (utilizing G711); my upload bandwidth will get
saturated as all of them have to go via my Asterisk server (according do
Digium support).  

They don't support bridging mode.  I think this limitation seriously
cripple these devices.  
Why is so hard to implement bridging?  Any links explaining how is it
done? 
How FWD solved this problem?
