Detailed Description

Call Detail Record API.

Author:

Mark Spencer <markster@digium.com>

Note:

Includes code and algorithms from the Zapata library.

We do a lot of checking here in the CDR code to try to be sure we don't ever let a CDR slip through our fingers somehow. If someone allocates a CDR, it must be completely handled normally or a WARNING shall be logged, so that we can best keep track of any escape condition where the CDR isn't properly generated and posted.
