This is not correct.
ACKs are not sent in response to 1xx-class provisional messages,
except when PRACK (100rel) is used--which your sentence does not imply.
The CDRs put out by 'acc' are digests of various call progress events;
it is up to you to calculate the time difference between a 200 OK
(in response to an INVITE transaction if you wish) and a BYE, using,
for example, database triggers.
The solution to this problem does not revolve around the use of a
media proxy, nor is reliance on a media proxy intrinsically "more
accurate."
