I love your ideas :-) As ususally, two brains are still thinking better 
then one ;-) Thanks a lot.

For archives, FXOexten being the FXO EndPoint in sip.conf Below 4000ms 
it's not working in our case. Perhaps something to do with early dial or 
others phone features.

exten => 300,1,dial(SIP/FXOexten,,M(WaitDialTone))

[macro-WaitDialTone]
exten => s,1,SendDTMF(9|4000)                   ;sending PSTN prefix 
with a 4s timeout
exten => s,n,SendDTMF(CallingNumber)     ;send number as DTMF

This does the trick.
