ARI sometimes plays back the same message for different voicemails

This isn’t consistent, but my customers (and I’ve seen this as well) will click on speaker icon in the top message in ARI (Asterisk Recording Interface) and the message will play back. But then the next message down will play the exact same message. The download icon exhibits the same behavior.

The messages have different lengths, caller ID’s, etc. I’ve seen this exhibited in both IE and FireFox, as well as in the QuickTime and Windows Media Player plug-ins. So, I’m guessing it’s not browser, plug-in related.

However, it’s sporadic. Anyone see this or have any ideas? I’m on the latest version of FreePBX and ARI, although this behavior was in earlier versions as well.
