<body>thx sergio<BR>
I'll have to feddle with it a bit and i'll come back to you.<BR>
The good news is that for people that don't have a PRI to play with, some voip provider that have g711 codec ( most of them) sends you the h223 msg in raw<BR>
I've been capable of seeing raw frames and can identify the flag ( have to inverse them tho: 11000101 -> 10100011)<BR>
What I need to do now is an Echo() so i see if there are more going on.<BR>
