I’ve been thinking a lot about analog telephone adapters (aka ATAs) recently. I truly feel that these devices are remnants of an earlier stage in the development of VoIP services. We still have one installed and running in our house, a Linksys SPA-2102. I’m hoping to be rid of it soon. I very much feel that, with one or two exceptions, ATAs should be avoided if at all possible. I’m working to get the basis for this assertion documented. In the mean time, Corey Andrews has some sage advice on how to pick an ATA…if you really must go that route.
