asterisk users - Sep 2005 - asterisk@home and zaphfc dial out not working

Hello,

 I have asterisk@home with zaphfc patch applied
 (http://dondisperato.blogspot.com/), but I can not make call to 
 legacy PBX (Alcatel 4400). I can only accept incoming calls.

 I am dialing with this: exten => 202,1,Dial(Zap/g1/242)
