+Colorful display+Smart features+Built-in Wi-Fi
Reasons to avoid
-Wi-Fi occasionally cuts out

Cisco calls this model a handset that’s ‘as smart as any smartphone’, which is a contentious claim (excuse the pun) and doesn’t quite ring true (and again). However, it is one of the most feature-packed on our list, featuring built-in Wi-Fi without the need for a dongle. The SPA5252G also can transfer calls to a smartphone to easily take a call out of the office. Most impressive of all is its support for Cisco MonitorView, which allows you to stream video to its 3.2-inch color display from a remote IP camera.
