Call data records can be stored in many different databases or even CSV text. MSSQL: Asterisk can currently store CDRs into an MSSQL database in two different ways: cdr_odbc.c or cdr_tds.c Call Data Records can be stored using unixODBC (which requires the FreeTDS package) [cdr_odbc.c] or directly by using just the FreeTDS package [cdr_tds.c] The following provide some examples known to get asterisk working with mssql. NOTE: Only choose one db connector. ODBC [cdr_odbc.c]: Compile, configure, and install the latest unixODBC package: tar -zxvf unixODBC-2.2.9.tar.gz && cd unixODBC-2.2.9 && ./configure --sysconfdir=/etc --prefix=/usr --disable-gui && make && make install Compile, configure, and install the latest FreeTDS package: tar -zxvf freetds-0.62.4.tar.gz && cd freetds-0.62.4 && ./configure --prefix=/usr --with-tdsver=7.0 \ --with-unixodbc=/usr/lib && make && make install Compile, or recompile, asterisk so that it will now add support for cdr_odbc.c make clean && make update && make && make install Setup odbc configuration files. These are working examples from my system. You will need to modify for your setup. You are not required to store usernames or passwords here. /etc/odbcinst.ini [FreeTDS] Description = FreeTDS ODBC driver for MSSQL Driver = /usr/lib/libtdsodbc.so Setup = /usr/lib/libtdsS.so FileUsage = 1 /etc/odbc.ini [MSSQL-asterisk] description = Asterisk ODBC for MSSQL driver = FreeTDS server = 192.168.1.25 port = 1433 database = voipdb tds_version = 7.0 language = us_english Only install one database connector. Do not confuse asterisk by using both ODBC (cdr_odbc.c) and FreeTDS (cdr_tds.c). This command will erase the contents of cdr_tds.conf [ -f /etc/asterisk/cdr_tds.conf ] > /etc/asterisk/cdr_tds.conf NOTE: unixODBC requires the freeTDS package, but asterisk does not call freeTDS directly. Setup cdr_odbc configuration files. These are working samples from my system. You will need to modify for your setup. Define your usernames and passwords here, secure file as well. /etc/asterisk/cdr_odbc.conf [global] dsn=MSSQL-asterisk username=voipdbuser password=voipdbpass loguniqueid=yes And finally, create the 'cdr' table in your mssql database. CREATE TABLE cdr ( [calldate] [datetime] NOT NULL , [clid] [varchar] (80) NOT NULL , [src] [varchar] (80) NOT NULL , [dst] [varchar] (80) NOT NULL , [dcontext] [varchar] (80) NOT NULL , [channel] [varchar] (80) NOT NULL , [dstchannel] [varchar] (80) NOT NULL , [lastapp] [varchar] (80) NOT NULL , [lastdata] [varchar] (80) NOT NULL , [duration] [int] NOT NULL , [billsec] [int] NOT NULL , [disposition] [varchar] (45) NOT NULL , [amaflags] [int] NOT NULL , [accountcode] [varchar] (20) NOT NULL , [uniqueid] [varchar] (32) NOT NULL , [userfield] [varchar] (255) NOT NULL ) Start asterisk in verbose mode, you should see that asterisk logs a connection to the database and will now record every call to the database when it's complete. TDS [cdr_tds.c]: Compile, configure, and install the latest FreeTDS package: tar -zxvf freetds-0.62.4.tar.gz && cd freetds-0.62.4 && ./configure --prefix=/usr --with-tdsver=7.0 make && make install Compile, or recompile, asterisk so that it will now add support for cdr_tds.c make clean && make update && make && make install Only install one database connector. Do not confuse asterisk by using both ODBC (cdr_odbc.c) and FreeTDS (cdr_tds.c). This command will erase the contents of cdr_odbc.conf [ -f /etc/asterisk/cdr_odbc.conf ] > /etc/asterisk/cdr_odbc.conf Setup cdr_tds configuration files. These are working samples from my system. You will need to modify for your setup. Define your usernames and passwords here, secure file as well. /etc/asterisk/cdr_tds.conf [global] hostname=192.168.1.25 port=1433 dbname=voipdb user=voipdbuser password=voipdpass charset=BIG5 And finally, create the 'cdr' table in your mssql database. CREATE TABLE cdr ( [accountcode] [varchar] (20) NULL , [src] [varchar] (80) NULL , [dst] [varchar] (80) NULL , [dcontext] [varchar] (80) NULL , [clid] [varchar] (80) NULL , [channel] [varchar] (80) NULL , [dstchannel] [varchar] (80) NULL , [lastapp] [varchar] (80) NULL , [lastdata] [varchar] (80) NULL , [start] [datetime] NULL , [answer] [datetime] NULL , [end] [datetime] NULL , [duration] [int] NULL , [billsec] [int] NULL , [disposition] [varchar] (20) NULL , [amaflags] [varchar] (16) NULL , [uniqueid] [varchar] (32) NULL ) Start asterisk in verbose mode, you should see that asterisk logs a connection to the database and will now record every call to the database when it's complete. MYSQL: PGSQL: If you want to go directly to postgresql database, and have the cdr_pgsql.so compiled you can use the following sample setup. On Debian, before compiling asterisk, just install libpqxx-dev. Other distros will likely have a similiar package. Once you have the compile done, copy the sample cdr_pgsql.conf file or create your own. Here is a sample: /etc/asterisk/cdr_pgsql.conf ; Sample Asterisk config file for CDR logging to PostgresSQL [global] hostname=localhost port=5432 dbname=asterisk password=password user=postgres table=cdr ;Now create a table in postgresql for your cdrs ;SQL table where CDRs will be inserted ;Copy and paste this into your postgresql prompt. CREATE TABLE cdr ( calldate time NOT NULL , clid varchar (80) NOT NULL , src varchar (80) NOT NULL , dst varchar (80) NOT NULL , dcontext varchar (80) NOT NULL , channel varchar (80) NOT NULL , dstchannel varchar (80) NOT NULL , lastapp varchar (80) NOT NULL , lastdata varchar (80) NOT NULL , duration int NOT NULL , billsec int NOT NULL , disposition varchar (45) NOT NULL , amaflags int NOT NULL , accountcode varchar (20) NOT NULL , uniqueid varchar (32) NOT NULL , userfield varchar (255) NOT NULL ); SQLLITE: RADIUS: See doc/radius.txt for more information on cdr_radius
