asterisk users - Aug 2005 - Zap with fax outbound signature

Hi,

I have a fax connected to a zap interface. When I dial out however 
asterisk says:

     -- Executing Dial("Zap/1-1", "Zap/g1/25") in new stack
     -- Requested transfer capability: 0x00 - SPEECH

And obviously the remote fax will not pick up as the call is not 
signalled as fax but speech. If I set the remote machine to pickup for 
any call it works well... but not many faxes are set this way. How can I 
solve this problem?

Best regards,
Arik
