ODBC using cel_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 cel_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

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

		[ -f /etc/asterisk/cel_tds.conf ] > /etc/asterisk/cel_tds.conf
NOTE: unixODBC requires the freeTDS package, but asterisk does not call freeTDS directly.

Now set up cel_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/cel_odbc.conf
		   [global]
		   dsn=MSSQL-asterisk
		   username=voipdbuser
		   password=voipdbpass
		   loguniqueid=yes
And finally, create the 'cel' table in your mssql database.
		CREATE TABLE cel (
				[eventtype]     [varchar] (30)          NOT NULL ,
		        [eventtime]     [datetime]              NOT NULL ,
		        [cidname]       [varchar] (80)          NOT NULL ,
		        [cidnum]        [varchar] (80)          NOT NULL ,
		        [cidani]        [varchar] (80)          NOT NULL ,
		        [cidrdnis]      [varchar] (80)          NOT NULL ,
		        [ciddnid]       [varchar] (80)          NOT NULL ,
		        [exten]         [varchar] (80)          NOT NULL ,
		        [context]       [varchar] (80)          NOT NULL ,
		        [channame]      [varchar] (80)          NOT NULL ,
		        [appname]       [varchar] (80)          NOT NULL ,
		        [appdata]       [varchar] (80)          NOT NULL ,
		        [amaflags]      [int]                   NOT NULL ,
		        [accountcode]   [varchar] (20)          NOT NULL ,
		        [uniqueid]      [varchar] (32)          NOT NULL ,
		        [peer]          [varchar] (80)          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 desired channel event at the moment it occurs.
