If you think you have managed to detect the end of a call more successfully 
than A2Billing can, I would have thought the logical solution would be to 
patch A2Billing to work with your improved teardown detection.

Not really.  The problem is inherent to analogue lines; which by definition 
cannot carry full supervisory information, as there is no separate D-channel.

Get some form of digital phone line  (such as a SIP trunk, or ISDN)  installed 
instead.  You should be able to switch from analogue to ISDN without 
terminating your existing telco contract; and the quarterly will be cheaper, 
as you are using less of the telco's equipment.
