[Asterisk-Users] Can audio streams go client to cleint with IAX?

[Jim Flagg]

With a service like http://www.freshtel.net/?show=home that uses IAX and has servers in Australia,
is it possible for the  audio streams to take a different path than the call setup and control?
In other words can it work like SIP with canreinvite where the two endpoint negotiate audio
streams between themselves rather than though the FreshTel server?

Thanks
