[asterisk-bugs] [JIRA] (ASTERISK-30408) Conflicting filenames in media cache cause wrong prompts to play

[Nathan Bruning (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-30408?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nathan Bruning updated ASTERISK-30408:
--------------------------------------

    Description: 
We encountered a rare case in which asterisk would play a completely wrong audio file during {{Playback(http://)}}, but only for certain callers.

It turns out that the media cache can get into a situation where two files (from completely different http urls) are stored with the same basename, only differing in extension:

- {{/tmp/bucket-111111.wav}}
- {{/tmp/bucket-111111.wav16}}

Asterisk will then pick one of the two depending on the codec selection of the caller.

I'll provide a patch shortly that makes sure that each cache name (bucket-xxx) is unique for all extensions.
