He says that the line does not support polarity reversal. It really 
depends on the type of PSTN interface he is using, but this probably 
means that the duration and the billsecs fields are going to be the 
same, as the channel gets answered and the ring-back tone is also counted.

I would rather say that if you do not have a proper way to detect the 
call progress, the system is not reliable for billing your users.

The main problem with the 30 seconds solution is that you will have a 
lot of calls made without charge (ie: 3 seconds ringing, 20 seconds 
call). And you will also charge people for ringing a phone during more 
that 30 seconds (ie: calling my grandma)
