asterisk users - Sep 2004 - Spawn extension.....exited non-zero

I am recieving inbound calls to my asterisk box over IAX.
And getting "spawn extension....exited non-zero" errors.
Im not entirely sure what this means, and would appreciate any help in 
fixing my problem.
FYI:
********** is the inbound phone number
x.x.x.x is a remote asterisk box calling my own asterisk box.

When I choose it to dial an internal extension using this dialplan:

exten => *********,1,Dial(${GRANDSTREAM},20);

the phone "blips" and I get this error in the asterisk console:

-- Accepting unauthenticated call from x.x.x.x, requested format = 8, actual 
format = 2
    -- Executing Dial("IAX2/*********@*********/1",
"SIP/grandstream|20") in
new stack
    -- Called grandstream
  == Spawn extension (inbound, *********, 1) exited non-zero on 
'IAX2/*********@*********/1'
    -- Hungup 'IAX2/*********@*********/1'

And if I try to just answer the call and play a message using this dialplan:

exten => *********,1,Answer
exten => *********,2,BackGround(demo-congrats)

I get this error:

    -- Accepting unauthenticated call from x.x.x.x, requested format = 8, 
actual format = 2
    -- Executing Answer("IAX2/*********@*********/5", "") in
new stack
    -- Executing BackGround("IAX2/*********@*********/5",
"demo-congrats")
in new stack
    -- Playing 'demo-congrats' (language 'en')

never be called!

If this helps:

I am running on FreeBSD (my previous asterisk server was also freebsd and 
with no problems)
My processor is hyperthreading (a first for me - but i read there may be a 
problem with it?)

Greetings,

I've just gotten asterisk working such that it will accept incoming calls 
and play the "demo" recording (from "make demo") during the
install.

However, on the console of the machine asterisk is running on, I'm getting 
"sound recording overrun" errors.

The only other indicator I'm getting is from the asterisk
"messages" file,
"Sep 14 14:40:58 WARNING[1110678320]: Failed to write frame"

Can anyone tell me what problem might be indicated here?

TIA for any suggestion/hints/pointers,

--Duncan

Yeah I have read there may be a problem with it to.  If possible, it  
would be worth testing with HT turned off and post your results.

Also, if this does not work, maybe it would pay to post some more of 
your config files (i.e. obfuscated iax.conf, more of extensions.conf 
and possible some of your sip.conf).
