In reading the SIA documentation for an Alarm Receiver application, the 
device sends (and expects) both DTMF and single frequency tones 
depending on the situation.  I see that dialplans can include checking 
for single frequency tones, but I didn't see any reference to being able 
to decode these from LUA.  Is that something that would be easy to 
implement?  Where might I start looking to do so?  Sending of tones 
could be accomplished via a .wav file so that part is covered.

Thanks,
Jim.
