The new phone does triple-duty as a landline, VoIP phone or Bluetooth headset.

Plantronics’ new Calisto Pro phone features a landline phone and a wireless headset. Over a built-in USB connection, the phone can make calls over Skype or similar VoIP services. Also, using Bluetooth, the phone can connect users to calls on their cell phones. The phone uses DECT technology for landline calls, and claims a range of up to 300 feet.

A bit pricey at $280, we imagine this device would be a lifesaver if you really do have calls coming in over land, WAN and air. An interesting side note: we don’t usually parrot PR reps trying to convince us to cover a product, but our Plantronics rep sent along this gem of a fact: “23% of home pros surveyed say they’ve “done their business” while doing business on the phone. No doubt, that task would be a lot easier with the Calisto Pro.” No doubt, indeed.

Look for the Calisto Pro in big box office supply stores and online in September.

There’s a mobile phone-like portion to the equation that you can use, if you prefer to have a conventional phone-yakking experience, but there’s also a Bluetooth headset included as part of the package if you need to keep your hands free for whatever reason. Regardless of whether the call is through a landline, your cell phone, or VoIP, the Plantronics Calisto Pro will funnel it all to a single device.
