Asterisk can currently store CDRs into a Microsoft SQL Server database in two different ways: cdr_odbc or cdr_tds

Call Data Records can be stored using unixODBC (which requires the FreeTDS package) cdr_odbc or directly by using just the FreeTDS package cdr_tds. The following provide some examples known to get asterisk working with mssql.

Icon

Only choose one db connector.

ODBC using cdr_odbc

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.
make clean && ./configure --with-odbc && 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
Icon

Only install one database connector. Do not confuse asterisk by using both ODBC (cdr_odbc) and FreeTDS (cdr_tds). This command will erase the contents of cdr_tds.conf

[ -f /etc/asterisk/cdr_tds.conf ] > /etc/asterisk/cdr_tds.conf
Icon

unixODBC requires the freeTDS package, but asterisk does not call freeTDS directly.

Now set up 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] (150) 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, using cdr_tds

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.
make clean && ./configure --with-tds && make update && make && make install
Icon

Only install one database connector. Do not confuse asterisk by using both ODBC (cdr_odbc) and FreeTDS (cdr_tds). 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] (150) NULL , 
        [userfield] [varchar] (256) 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.

    error was --with-unixodbc unknown variable while using configure for freetds

     tar -zxvf freetds-0.91.tar.gz && cd freetds-0.91 && ./configure --prefix=/usr --with-tdsver=8.0  --with-unixodbc=/usr/src/unixODBC-2.3.0 && make && make install (note: -withunixodbc=(path to where unixodbc is installed)

    This worked for me !!
