Just have in thoughts that this time will be the time between the ACK related to the "18x-Progress" message and the BYE.

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."
