I'm looking for a simple ATA to hang off an existing Huawei HG630b Spark modem/router on an existing Spark VDSL connection and connect up to an existing 2Talk service. There will only be one cordless DECT phone attached, and only one 2Talk VOIP account involved (i.e. very simple setup).

I want something that is proven to work well with the 2Talk system with minimal hassle. Preference is for something that is easy to auto-provision, but I'm happy to manually configure if required.

What's the current recommendation? I see a few older threads mentioning the Cisco SPA122, is that still my best bet?
