asterisk users - Mar 2004 - asterisk & deltathree (iconnect) directly media stream

Hello,

I setup my asterisk with deltathree (iconnect) account. 
I have local sip account like 888xxx for local use and deltathree account 
for externall cals 33455655343.  
All works fine throught asterisk, also media stream comes throught asterisk.  
But i have problem with setup asterisk -> deltathree connection with directly
media stream.

Anyone can help me ?
