Thanks to everyone who has replied so far; to answer a few of the follow up questions that have been posed:

For firmware I've tried everything from 8.3.5 up to 8.4.2 with no concrete change (there was one version of 8.3.x that "seemed" to be a little worse, but with how hit or miss it is who knows what reality was) The other thing that's been driving me crazy is we have an Asterisk Appliance in one of our remote offices, and while the Appliance is a PITA to admin, neither of the users over there have reported any issues with any of the FW images I've pushed out. > Have you run a packet cap on a mirror of the switchport the phone this is > happening on is connected to?

I'll need to set something up to do a packet cap; the network itself is relatively quiet, and I've been able to reproduce the issue after hours so user-generated traffic isn't in play. The * server also hosts Flash Operator Panel and Zaptel (4 FXO lines) but that's it. There are only 5.5 FTEs and 7 sets in this office so I can't imagine that we're putting that much stress on the box.

Nope, Asterisk box and phones are on the same subnet and VLAN with no routing or firewalling between the two. In fact, the phone that experiences the issue most frequently is connected to the same physical switch as the Asterisk box.

Not sure how to answer the "announce" question -- when I searched voicemail.conf nothing was found. Thanks again!
