How to place outgoing calls on DTI300SC with runtime driver ?

Hi,

I need to make outgoing calls with my dti300sc with the following script:
-------------------------------------------
slog.crit "Starting DialTest"
dial 6 "04 93 97 71 76"
speak &spell 1
exit
^busy
    slog.crit "Busy !!!"
    hangup
^answer
@dial:answer
    slog.crit "Answer !!"
    hangup
^ring
    slog.crit "Ring !!"
^timeout
    slog.crit "timeout"
# @dial:reorder # dialing reorder tone heard
#    slog.crit "reorder"
# @dial:nodialtone # no dialtone in dial command
#    slog.crit "no dialtone"
# @dial:noringback # no ringback heard
#    slog.crit "no ringback"
# @dial:noanswer # nobody answered call
#    slog.crit "no answer"
# @dial:busy # caller was busy
#    slog.crit "busy"
# @dial:answer # answer detection confirmed
#    slog.crit "answer"
hangup
exit
-------------------------------------------------

Everytime I start the script I get the timeout event, i hear the phone 
ringing but only a few seconds before the script exits and no way to get 
it work  :/

I absolutly needs  the runtime dialogic driver because I work with both 
digitals and analog cards.

Is there a way to get it working or at least why the timeout event is 
raised ?
