I have similar problems, and asterisk seems to have real trouble 
determining a ring when the cadence varies. Cadence 2 is interpreted as 2 
rings for example. I find when the first ring is a partial ring this is the 
real problem (why in this day of computers there are partial rings ever I 
have no idea)

What is the exact status of cadence detection in asterisk now ? Can it be 
used to determine the context of an incoming call yet ? (reliably)
