And, if you are interested, for myself I use VOIP for the features – call screening that can’t be circumvented by caller-ID spoofing and relays text messages and can be configured to easily prevent unwanted calls and then routes them to my cell phone if I am not home. I can easily make multi-person conference calls or have more than one instance of my number making outgoing calls at the same time and switch between them if I am on hold. For a few dollars more a month I also have a PIN-protected toll-free number I can call to get voice mail and also make outgoing calls in case I lose or break my phone. Basically, an office-quality telephone service (and configurable PBX to boot) from home. And VOIP phones are really cheap on e-bay. Plus text messages come to (and can be sent from) my home desk VOIP phone as well as my cell phone so my cell phone can charge uninterrupted while at home and I don’t miss anything. And a hard-wired (to my home internet) VOIP phone (while not the voice quality of an actual land-line-copper-wire-POTS phone – nothing is, IMHO) is usually a bit better than a cell phone while retaining most of the advantages and not irradiating my head.
Just my two cents.
