For the most part, video conferencing solutions
can be divided into two categories. There are prohibitively-expensive video conferencing room kits that cost tens of thousands of
dollars. Then there are software programs that run on your PC or Mac (think
Skype, GotoMeeting, or Bria).
But now a third category is emerging. Some
of the most popular VoIP hardware manufacturers are releasing VoIP desk phones
with video capabilities. Industry leader Polycom released its VVX
1500 business media phone back in 2009, a little ahead of the pack. If
your Polycom executive desk phone had a baby with a video conferencing system,
it would probably turn out something like the Polycom VVX 1500.
This phone can be split into two
parts. First, there's the phone itself, which features a very sleek,
professional design. All of the hardware components are done
exceptionally well. The handset is just the right weight. The hard
keys are big, clearly labeled, and satisfying to use. The speakerphone is
probably one of the best we've ever encountered on a desk phone.
Strapped to the back of the phone is the second
part of the device: the 7-inch touchscreen TFT-LCD and 2-megapixel
camera. The display is connected to the phone on a hinge so users
can adjust it to get the perfect viewing angle for video calls and menu
options. The camera can also be tilted up or down independently.
The LCD on the VVX 1500 is probably the nicest
one I've tried on a VoIP phone. The touchscreen is very responsive –
rarely did I ever have to tap an option more than once to get it to
register. Scrolling through menus on the VVX 1500 by running your finger
across the screen can be a little frustrating, however. Luckily,
users can just as easily navigate through any of the menus on the LCD using the
hard keys provided on the phone. Some may even prefer to use the
hard keys exclusively, and to forego the touch screen
altogether. It's really up to you.
In Use
The Polycom VVX 1500 uses the G.722 wideband
codec as the default audio codec. So, if you're VoIP-calling someone else on a
phone that also supports G.722, you can expect fantastic audio
quality. Polycom's "HD voice" is more than just audio
codecs. The company has spent a lot of effort incorporating hardware
and software enhancements into its executive phones that work together to
deliver the best audio quality, and you can bet that some of those enhancements
are in the VVX 1500.
As already mentioned, the speakerphone on the
VVX 1500 is fantastic. The quality is akin to what you get from
Polycom's dedicated conferencing solutions.
We also conducted a number of video-calling
interoperability tests. As expected, video calls between VVX 1500s
were exceptional in both audio and video quality using the H.264 video
compression standard. Video calls using H.264 didn't seem to work when we
tested the VVX 1500 with the Bria for Mac and the Grandstream GXV 3175, but we
were able to get full interoperability when we switched to H.263.
Other highlights of the phone include business
productivity applications. Polycom has its own licensed Productivity Suite
that users can try out when they boot the VVX 1500 by using a provisioning
server that has a correct license file. Companies can also use
Polycom's open developer API to build customized business applications for this
phone.
Finally, we come to the microbrowser, which allows
users to easily navigate to customized web pages. It is also
possible to browse the Internet, but I wouldn't recommend it. Load
times can be slow, and the processing power on the phone isn't quite high
enough to handle some web pages.
