[Asterisk-Users] 404 "Not Found"

[clint_in_sydney]

Hi all, I get an engaged tone and the following when I dial out. 

-- Called myhomeno at byo.engin.com.au 
-- Got SIP Response 404 "Not Found" back from 202.61.13.40 
-- SIP/byo.engin.com.au-???? is circuit-busy 

To me this suggests that the engin server can't find my PSTN...

Does anyone have any ideas as to what I should look for? 

Cheers, 

Clint
