需要修改的配置文件：

switch.conf.xml //核心表 

cdr_pg_csv.conf.xml //通话记录 db.conf.xml //核心表 
voicemail.conf.xml //留言相关的表 
internal.xml // 
external.xml // 
fifo.conf.xml //fifo相关的表 
callcenter.conf.xml //callcenter程序相关的表。

1、switch.conf.xml

2、cdr_pg_csv.conf.xml

3、db.conf.xml、voicemail.conf.xml、internal.xml、external.xml、fifo.conf.xml、callcenter.conf.xml 

或者在var.xml追加以下配置，然后去注释db.conf.xml、voicemail.conf.xml、internal.xml、external.xml、fifo.conf.xml、callcenter.conf.xml 中的" "

【附】xml_cdr建表sql及cdr_pg_csv.conf.xml 字段设置

【附】录音文件路径写入数据库：

dialpanl/default.xml中添加一行，定义录音文件路径

再在autoload_configs/cdr_pg_csv.conf.xml的字段定义中添加一行

最后在数据库表中添加一个字段
recording_file

重新加载模块reload mod_cdr_pg_csv
再打电话就有录音路径生成了
