Asterisk + ODBC + MySql


I need to know if to make Asterisk Realtime work with ODBC I need to install Asterisk-Addon.

When I do the ‘odbc show’ command I can see the connection with the Database, but when I try to insert user in the sipusers table, users can’t register.

I have already changed sip.conf and extconfig.conf.

Do I have to insert some reference to the database also in the sip.conf?

Please, Help Me…
