-Asterisk now generates Call Detail Records.  See include/asterisk/cdr.h for
-all the fields which are recorded.  By default, records in comma-separated
-values will be created in /var/log/asterisk/cdr-csv.  You can specify 
-account codes and AMA (Automated Machine Accounting) flags on a per-channel
-(Zaptel et al) or per-user (IAX) basis to help with accounting.  Look
-at the top of cdr/cdr_csv.c to see the format for the records.  
+Asterisk billing support - Call Detail Records
+----------------------------------------------

+     default driver
+   * cdr_odbc supports UnixODBC databases, see http://www.unixodbc.org
+     for an updated list of supported databases, from MySQL to MsSQL
+     and text files.
+
+
+
+Applications

+
+    * Asterisk cmd setaccount: Set accound code for billing
+    * Asterisk cmd NoCDR: Make sure no CDR is saved for a specific call
+    * Asterisk cmd resetCDR: Reset CDR
+    * Asterisk cmd authenticate - Authenticates and sets the account code
+    * Asterisk cmd SetCDRUserField - Set CDR user field
+    * Asterisk cmd AppendCDRUserField - Append data to CDR User field

 you need to be aware that by default, IAX will attempt to transfer calls

 will report a short call time.  If you want detailed records you must
 turn off IAX transfer, but unless your servers are very close together, you
 will definitely get a latency hit from doing so.
