asterisk users - Jan 2005 - Read() timeout hangs up the line

Hi list,

I am having some difficulty implementing a certain dialplan where the 
following
happens. If the first Dial() is not answered, I want to play a small 
greeting then
ask the caller to either hold the line (try calling again) or press 1 
to leave
voicemail.

exten => s,1,Dial(${BLAH},10,Tt)                         ; Dial 10 sec
exten => s,2,Answer
exten => s,3,Playback(greeting)
exten => s,4,Playback(werebusy)
exten => s,5,DigitTimeout(1)
exten => s,6,ResponseTimeout(3)
exten => s,7,Read(WHAT,holdormsg,1)             ; "Hold the line, or 
press 1 to leave a msg.."
exten => s,8,Gotoif($[${WHAT} = 1]?30)
exten => s,9,Dial(${BLAH},15,Ttm)                       ; Dial another 
15 sec with music on hold
exten => s,10,Goto(7)                                   ; Loop

My problem is that if the caller doesn't press a key when prompted, and 
the Read()
is allowed to time out (3 seconds), (s,7) returns non-zero and asterisk 
hangs up
on the caller without further execution. I want it to continue down the 
priorities and
redial the line, with hold music..  It doesn't even get to test the 
value of ${WHAT}
if nothing is entered. However, if the caller enters an number other 
than 1, it will
perform properly and redial the line.

     -- Executing Read("vpb/1-1", "WHAT|holdormsg|1") in new
stack
     -- Accepting a maximum of 1 digits.
     -- Playing 'holdormsg' (language 'en')
     -- User entered ''
   == Spawn extension (blah, s, 9) exited non-zero on 'vpb/1-1'
   == vpb/1-1: Hangup requested
   == vpb/1-1: Ending record mode (1/yes)
   == vpb/1-1: Ending play mode on vpb/1-1
   == vpb/1-1: Hangup complete

Any ideas what could be wrong ?

Cheers
Troy

As far as I can see the problem is with the Read() function.

When this function times out due to no user input, the extension is 
terminated
and the call is hung up. Maybe this was the intended behaviour, but I 
can't see
how its of any use.. Surely this is not the most desirable behaviour ?

Please anyone who can shed some light ? or offer a workaround ?
