Have you found a resolution yet? I notice this was posted almost 4 months ago.
I have almost the same config as you although I run SpF. Got the right 6608 load, tried upgrading to TSP 7.0.1 which TAC recommended still the same thing. Happens both via PSTN gateway and IP phone and only on Unity prompts. We don't use transcoding on the 6608 and all G711. Single site - no WAN links - 100MB switched - low volume of voice mail usage and plenty of bandwidth.
I'm trying to figure out how are Unity prompts processed that is different from playback of subscriber greetings and messages. Ours actually degraded over time. First was only when calling from the "outside" to check voice mail & very rare. Then it started increasing such that almost every time I called from the outside a portion of the Unity prompt would be robotic. Finally, a few weeks ago I started hearing it internally from our IP phones.
I have opened a TAC case, but curious if anyone has discovered anything new.
There might be some configuration settings for minimum, maximum and
nominal playout delay on the CCM admin on the Gateway age, and there should be comparable settings within IOS for the same thing.
I'm not sure exactly what changes need to be made, but if the site has not been releived by the load that was specified in CSCdx36894, I'd recommend either contacting TAC, or trying IP telephony forum. There's probably better experience with the GW configuration there.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
