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."
