This is a very good phone, I have setup 4 SIP accounts and work just fine.
the sound quality is crystal clear. So far so good this is the best IP phone you can get for this price.

Purchased 13 of these for the office... Great phone - pair it up with Jive Communications for your provider and you have a great combo. Cisco quality and support.

The backlights on these phone burn out quickly
11 Mar 2011
Amazon Verified Purchase
I bought 10 of these phones for a small business and within 2 weeks the backlights on the displays went dark on all the phones. I replaced two of these phone under warranty and the backlights on the replacements also failed. (Note that you need to pay for the return shipping, and Cisco charges big $ if you want them to send you a replacement first before you return your broken phone.) This is a problem Cisco obviously knows about but does not know how to fix. (And no, I did not have the backlight setting to be on all the time.)

Great work phone
16 Sep 2011
Amazon Verified Purchase
The form factor of these phones are both visually appealing and physically comfortable to work with on a daily basis. We are using them for a Ring Central account and the setup was a breeze - even for the non-technical people. I would make one technical recommendation to purchasers: these do not come with a power supply. If you are a medium sized or larger office (not just 1 or 2 people), then I would recommend purchasing a POE switch to power the phones instead of the $15 power brick. You can then setup a backup battery for both your POE switch and office internet router/modem. This way you can centrally power everything in case of a power outage.
