Review: Quality - Works as it should. This is a new item and has all the power cord. Even though one of the picture has the expansion but it does not come with it and I did not expected. Listing should have said "expansion not included". Otherwise, this one comes with power cord unlike some other reviews. Works great.
Review: Good quality phone to replace an older system - I ordered this to test with teams voice calling add-on, the handset is really solid feeling and simple set up, I was up and running in minutes. My only issue would be the software updates, I logged on to the Web interface and uploaded and ran the update, it's fine for a one off but I wouldn't fancy doing loads of phones. Perhaps this is really intended for home office and small office market. All in all a decent product, will be buying more I'm sure.

## Questions & Answers

**Q: Can you connect a normal land line phone line into this phone? Or is it Ethernet only?**
A: No. This VOIP phone is only designed to be used digitally. I have a Yealink MP56 Teams Phone and it connects directly to a network switch and then to a Fibre To The Premises router. You will also need a power supply unit. Great phones
