Any idea where I can find the "official" Australian telco tone
frequencies and their durations?  I asked an engineer friend of mine the
other day (he's now the longest serving Telstra employee in Australia), but
he told me that he does not have that info, nor is it readily available. 
Whilst the Courier's tone recognition is not user-programmable, I'd like to
pass on the details to USR, so that they might code their 061 SDLs detect
local tones a little better than they do right now.
