asterisk users - Jul 2006 - [oh323]FastStart/H245Tunnelling/H245inSetup

Hi all,

i have following setup

[6666]--[asterisk]--[oh323]--[HiPath]--[8000]


6666 is my voicemail access
exten => 6666,1,Answer()
exten => 6666,2,VoiceMailMain() 

8000 is an Optiset phone registered on the HiPath.
When 8000 calls 6666 i have no voice (depends on the
setting of FastStart). When FastStart=yes in oh323 the
caller can't hear the voivemail message (otherwise
(when FastStart=no) every thing works fine.

Can anyone explain the impact of FastStart?
What is the H245inSetup parameter?

thx in advance...
