>          Issue Type: Bug
>      Security Level: None

> 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.
