I have a couple of SPA-3000's here and find the quality to be quite good for the voice mail side of things. I'm still on a learning curve with Asterisk and haven't gotten rid of the echo on the extensions I've plugged into them though. When I'm using the IP phones or soft phones the quality is great. Voice mail sounds as about as good as a Nortel StarTalk I've had in the past. I am running small scale for now though and am handling on average less than 30 calls a day through asterisk.
If it helps you in your decision at all just let me know and you can always call my system from known equipment on your end and I can send you the voice mail as an email attachment so you can hear what the recorded quality is like.

I had also had problems with people leaving voicemail from time to time - their message is not audible on playback - just mostly background noise and the odd static as if when they raise their voice/tone slightly. A reboot seems to improve things for a while - but that seems a little to Windows-sy an answer. This has been the case with asterisk at home 1.5, 2.0 and now 2.1 (running asterisk 1.2.0/linux kernel 2.6). I have been considering the purchase of a Sipura 3000 since I could use an additional FXS as well, but only if this is the likely cause of the bad audio. Anyone care to share their successes/failures wrt call quality with Sipura 3000s? One more thing I have been banging my head on: I have a Sipura 2002 with two extensions connected. On one of those extensions I have two physical phones connected and there is an amazing amount of static occassionally on that extension but only when receiving a call. If I hangup and call the person back the call is clear. I have checked the cables running from the two phones to the Sipura 2002 and have not found any problems. I'm wondering how I might further isolate the problem - thinking as I'm typing here, maybe I could set that extension to always record and see if the recordings show the bad audio. Hmm.
