Re: [asterisk-users] Playback/background audio from MySQL BLOB

Is there another way to playback or background audio either by specifying a URL or from a memory buffer (either C or PHP)? Depending how many messages you have, you could use a named pipe (FIFO) or a Unix-domain socket for each one; and have the individual backend processes interrogate the database and dump the contents of the relevant field down it. As far as Asterisk is concerned, the socket / FIFO looks just like a file; it doesn't care much that the data in it is really coming from a process on the other end. This obviously suffers from the problem of decreasing manageability, the more message files you have. But personally, I'd just store the filenames in the database; and rely on the unix filesystem for storing the actual file contents. After all, that's what a filesystem is for. -- AJS Note: Originating address only accepts e-mail from list!

We solved this problem by storing the voicemail with IMAP. It is possible to access IMAP simultaneously from different locations, and a lot of implementations offer the ability to integrate IMAP into web-applications. That's how we did it anyway.

Why try to shoehorn a database into doing something it wasn't designed to do (and isn't particularly good at doing)?

Maybe someone could write a Linux device file that would return the blob's content as a file read. I beat you to that one ;) That is exactly what a named pipe (fifo) is. Asterisk would read it like a sound file, and the AGI would dump the BLOB to it on demand. It would work, but you can't have more than one process at a time reading from it, so that's a further complication... j -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
