Does anyone know about how caching of media actually happens in Asterisk 14?
What I observe is that in the case of a media uri being presented to Asterisk
to play to the caller, Asterisk fetches the media, stores it in /tmp and plays
it back. Now, when the same media uri is presented to Asterisk again whether in
the same Call (SIP session with a given caller) or a new call, Asterisk makes a
web request to fetch the media file again and replaces the existing file under
/tmp with the new one. This is kinda fine but what doesn't seem right is that
when Media server serving the media files is down, Asterisk fails to play it
instead of using the cached media file.

Has anyone seen the same thing? And, have any comments on how to get it to
behave right? My last resort is to patch Asterisk but wanted to find out how
others are doing before I start fixing it myself.
Thanks,
Gaurav
