Luego de aprender como guardar todos nuestros CDRs dentro de mysql, me ha surgido la duda de como migrar los ya existentes en el master.csv a la base de datos nueva, bueno primero explico algo de como y porque.

Por que:
Esto corriendo asterisk 1.4 y manejandolo con Vicidial (contact center app) pero este utiliza el custom_cdr.conf en donde el guardado en CVS esta definido de la siguiente forma:

Master.csv => "${CDR(clid)}","${CDR(src)}","${CDR(dst)}","${CDR(dcontext)}",
"${CDR(channel)}","${CDR(dstchannel)}","${CDR(lastapp)}",
"${CDR(lastdata)}","${CDR(start)}","${CDR(answer)}","${CDR(end)}",
"${CDR(duration)}","${CDR(billsec)}","${CDR(disposition)}",
"${CDR(amaflags)}",
"${CDR(accountcode)}","${CDR(uniqueid)}","${CDR(userfield)}"

Que significa esto ?? http://www.voip-info.org/wiki/view/Asterisk+billing

ahora bien he encontrado algunos scripts que dicen ser la herramienta mas util para este tipo de migracion lo cual luego de probarlos ha resultado falso!! jejeje

aqui les dejo el que yo modifique y utilize para que migrara de forma transparente los datos del Master.csv con la configuracion cdr_custom de vicidial.

<?php
/*** process asterisk cdr file (Master.csv) insert usage
* values into a mysql database which is created for use
* with the Asterisk_addons cdr_addon_mysql.so
* The script will only insert NEW records so it is safe
* to run on the same log over-and-over.
*
* Author: John Lange (john@johnlange.ca)
* Date: Version 2 Released July 8, 2008
*
*
* Here is what the script does:
*
* Parse each row from the text log and insert it into the database after testing for a
* matching "calldate, src, duration" record in the database. Note that not all fields are
* tested.
*
* If you have a large existing database it is recomended that you add an index to the calldate
* field which will greatly speed up this import.

?>

ahora la parte mas dificil, como ejecutarlo:

php import.php Master.csv

Nota: si por algun motivo no funciona el comando php, eso significa que no tienen el paquete php-cli para ejecutar sentencias php en linea de comando.
