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.
