A very practical discussion on how to connect Asterisk with Relational Databases using ODBC database abstraction layer. This session will cover the basics of MySQL/ODBC installation, configuration and integration with Asterisk. Additionally will be made practical examples about the benefits of this union: improving dialplan with SQL Queries, store Call Detail Records (CDR) in DB, implementing Realtime Architecture (ARA). Proposed session is for those who do not yet know benefits of connecting an Asterisk box to a database or are interested to learn about it through a very simple step-by-step demo.
