Not sure I understand the question, but I'll try and answer it anyways.

IAX and IAX2 is just like any other VoIP protocol and it only uses
bandwidth for active calls. If there isn't any active calls the
bandwidth used is very low and only what is necessary to confirm each
side is there and up. 

When one gateway machine takes the call and decides it needs to go to
the other side, the other side will answer the call immediately and yes
there is bandwidth then being used. Ideally either you are now playing
prompts from the newly connected to asterisk machine, or you are
connecting to a phone and the call is completed. 

Hope this helps a bit.
