[Asterisk-Users] fax extension isn't executed

[yamamoto at paak.co.jp]

Hi
I'm tring to use asterisk as IVR.  But I have trouble when I
recieve fax.
When I recieve fax, asterisk show message to looks redirect
incoming fax to "fax" extension. But scripts in "fax"
extension never execute. Timeout happen later(I think this
timeout is caused by DigitTimeout). 
Somebody have some suggestion?

Asterisk, zapata and zaptel is new CVS(1 week ago)
OS is RH8.0 
FXO is X100P only (connect PSTN)
no FXS

asterisk messages is below...
(asterisk -vvvdc)
    -- Set Digit Timeout to 10
    -- Set Response Timeout to 20
    -- Playing 'vm-extension' (language 'jp')
    -- Redirecting Zap/1-1 to fax extension
    -- Timeout on Zap/1-1
    -- Playing 'demo-thanks' (language 'jp')
    -- Hungup 'Zap/1-1'

extension.conf is below...
[mainmenu]
exten => s,1,Wait,2                     ; Wait a second,
just for fun
exten => s,2,Answer                     ; Answer the line

exten => t,2,Hangup                     ; Hang them up.
