What do you mean by 'bridging'? This is a single port device, it doesn't
have anything to bridge.

If you mean that you want two of them to be able to send the audio
streams directly to each other, then this can be done by setting
'notransfer=no' (for Asterisk 1.2) or 'transfer=yes' (for Asterisk 1.4),
to allow the Asterisk server to push the call out to the endpoints after
the call has been setup. Keep in mind though that you will lose control
of the call at that point, so if you need to keep accurate CDRs this
technique will not work for you (this is a limitation of the IAX2
protocol that has been rectified in Asterisk 1.4, but Asterisk 1.4 is
the only endpoint the currently implements IAX2 media-only transfers).
