Closelogicalchannel call termination procedure

Hi,

Actually, when i make a call with an openphone(openH323) to asterisk, everything is allright! During a call termination, with a signalling channel and a control channel open, an endpoint send an endsession to the other, answering by endsession as well and then, a releasecomplete clear the connection.

I need to call the H.245 call flow procedure in the stackH323:
requestchannelclose/requestchannelcloseAck/closelogicalchannel/closelogicalchannelAck

Is it already done? i cannot see it, how can a use it, is someone help me??
