The ODBC connector is a database abstraction layer that makes it possible for Asterisk to communicate with a wide range of databases without requiring the developers to create a separate database connector for every database Asterisk wants to support.
This saves a lot of development effort and code maintenance.
To install the ODBC drivers, use one of the following commands.
On Cent OS: file, which is used to create an identifier that Asterisk will use to reference this configuration.
This validator checks the markup validity of Web documents in HTML, XHTML, SMIL, Math ML, etc.
If you wish to validate specific content such as RSS/Atom feeds or CSS stylesheets, Mobile OK content, or to find broken links, there are other validators and tools available.
As for the validation - you may check your links to be valid - with in front and such.
There is a slight performance cost, because we are adding another application layer between Asterisk and the database, but this can be mitigated with proper design and is well worth it when you need powerful, flexible database capabilities in your Asterisk system.
