asterisk users - Jun 2005 - UK SMS Config problems

All,

I'm running CVS-HEAD as of 15thJune with an x100p and the x100p callerid 
patch.  I'm trying to use app_sms to recieve sms to my landline but get 
the following response.

Any ideas.

 -- Executing NoOp("Zap/1-1", "Testing without Answer
08005875290") in
new stack
    -- Executing GotoIf("Zap/1-1", "0?s|5") in new stack
    -- Executing GotoIf("Zap/1-1", "1?s|7") in new stack
    -- Goto (pstn-inbound,s,7)
    -- Executing Goto("Zap/1-1", "sms-in|s|1") in new stack
    -- Goto (sms-in,s,1)
    -- Executing Answer("Zap/1-1", "") in new stack
    -- Executing Wait("Zap/1-1", "1") in new stack
    -- Executing SMS("Zap/1-1", "default|a") in new stack

    -- SMS TX 92 01 FF 6E
    -- SMS TX 92 01 FF 6E
  == Spawn extension (sms-in, s, 3) exited non-zero on 'Zap/1-1'
    -- Hungup 'Zap/1-1'

And nothing in my /var/spool/asterisk.
