Then verify the audio with your favorite audio application, such as the play application:
# play /tmp/voicemail-47395.wav

Input Filename : /tmp/voicemail-47395.wav
Sample Size : 8-bits

Sample Rate : 8000

Time: 00:06.22 [00:00.00] of 00:00.00 ( 0.0%) Output Buffer: 298.36K
Done.
And now that we’ve confirmed everything was stored in the database correctly, we can
try listening to it via the VoicemailMain() application by dialing extension 200:

Conclusion

In this chapter, we learned about several areas where Asterisk can integrate with a
relational database. This is useful for systems where you need to start scaling by clus-
tering multiple Asterisk boxes working with the same centralized information, or when
you want to start building external applications to modify information without requir-
ing a reload of the system (i.e., not requiring the modification of flatfiles).
