Review: Unit not new. Listed as new - Unit has crack. Has been used.
Review: Works Great - Been using this product in our office. We added new work stations at our office and needed more phones. Its been working great since we've installed it. Easy configured and works with Skype SIP. Just remember if you dont have a POE (power of Ethernet router/switch) you will need to purchase the adapter which is sold separately. Another draw back to this phone is it is 10/100 Ethernet port, so if you utilize 1000 / Gigabyte routers, this phone pretty much makes that feature pointless.

## Questions & Answers

**Q: What firmware ver are the sets?**
A: You can update the firmware

**Q: We are interested in this product? Why is Aastra 6731i IP Phone Power Supply Not Included?**
A: Because in many installations the power is provided by a Power Over Ethernet Switch.   It is not all to common to require a power block for IP Phones and not including them provides a cost savings.If you are deploying an office phone system it would be best to use one of these POE Switchs to power the phones so that you can use a UPS on the switch and keep the phone phone system running in the event of a power outage.     I needed some power blocks for some of my remote users.   just buy them separate from the phones, no need to complain about it.
