I had exactly the same experience with the SPA-3000. Too bad too since it's nice device...if it were 6 db hotter. I also installed a TDM-400, which was better in a lot of ways but not perfect. When I rebuild my server I ended up simply call forwarding my POTS lines to a DID provided by an ITSP. This has been the best as far as quality is concerned. If my DSL line goes down I simply defeat the call forwarding on the main line and answer an analog phone for a while, or call forward to me cell.
