asterisk users - Dec 2005 - messages of Mobile Operator

Hi,
I have this problem. When I call a GSM number with the IDSN line if the 
GSM phone I not hear the messages of operator  but I hear the ring.
I suppose that the problem is that asterisk waits a response that is yet 
arrived.
Any idea?
This is my extension:
exten => _0XX.,1,Wait,1
exten => _0XX.,2,Dial(Zap/g1/${EXTEN:1},60,tT)
exten => _0XX.,3,Hangup

I'm registering the same problem, I think is a problem due to bristuff 
implementation, are you using bristuff? what version? what version of 
asterisk? What version of kernel? libc? distribution?
