Product Reviews
Rated 3.9 out of 5 by 13reviewers.
Rated 5 out of 5 by Its a decent phone that performs well. It feels little cheaply made (less heft or something) than our old Avaya phones, but I haven't had any users break them yet and they just work, so giving them 4 stars. I use them with Vonage. June 7, 2016
Rated 4 out of 5 by I administer the IT for a company with lots of these and they are excellent phones. Very reliable, great build quality and the call quality is also good. A gigabit port on the back would be nice though. August 25, 2015
Rated 4 out of 5 by Solid IP phone. We still have an office full of them. These are easy to setup using Cisco Configuration Assistant. The main problem with these is that the PC port is only 10/100 speed. November 13, 2014
Rated 5 out of 5 by This is a great entry-level SIP phone. It offers a lot of configuration options and it seems pretty reliable. I've had one on my desk for several years, and it's a good friend. March 24, 2014
Rated 5 out of 5 by Solid little phones. Easy to set up, works great with the UC320W for small offices, and the accessories available make my, and the boss's life a lot more comfortable. I have 12 of these deployed and not a problem with a single one. February 13, 2014
Rated 5 out of 5 by The classic Cisco phone that you would see EVERYWHERE. Seemed to be very reliable. I actually remember seeing this phone in the US show, "The Office" as well. February 6, 2014
Rated 4 out of 5 by Loved how easy these were to configure. The hardware is the same of Linksys.Can update firmware, and customize the ring tone with any song you like.(Update and customize with app free download). February 6, 2014
Rated 4 out of 5 by These phones are pretty stable on 3CX. Easy to provision and update firmware. The speakerphone is not great though. For more flexibility (more lines, BLF buttons, etc.) look at the SPA 509G and the SPA 525G for bluetooth and nicer display. April 16, 2013
