asterisk users - Apr 2014 - ICE

Hello,
I have an Asterisk server with a public IP address and a bunch of clients.
Most of my clients are behind NATs (sometimes two clients are behind the
same NAT i.e in the same private network). I want to use ICE so that the
clients behind the same NAT can send RTP traffic directly to each other and
other clients use Asterisk or a TURN server. I tested a specific scenario
using two Linphone 3.7 as clients behind the same NAT but finally traffic
ended in Asterisk. I checked the packets; the first client sends its host
and server reflexive candidates to Asterisk and Asterisk sends it's public
address. Then Asterisk will send it's own address to second client and
second client in the final 200 OK SIP only sends it's local address
normally without using ICE (ICE is enabled on both clients).
Using ICE for such a purpose is possible at all?

PS: in sip.conf I set directmedia=no and directrtpsetup=no.

Asterisk does not currently support this configuration (specifically 
passing through candidates and ICE information like this).
