Grandstream GXV3140 IP Phone


One of the most feature-rich phones around has to be the Grandstream GXV3140 IP Multimedia Phone. Grandstream was initially known as a low-cost provider of communications solutions but over time they have proven that they make low-cost solutions with solid quality.

This leads us to the end of this month when the company releases their new feature-rich videophone which has solid social networking features built-in. You can use the phone to IM over Google, MSN and Yahoo, track RSS feeds, listen to internet radio and also stream from the included SD card slot or USB port. There is also an alarm clock, calendar, music ring tones and 3-way conferencing.

 The phone also integrates with Yahoo's Flickr service so you can use it instead of a digital photo frame.

The color screen is 4.3" with 480x272 resolution and the camera supports 1.3 megapixels. There is support for a stereo headset with microphone, wideband/HD voice support, TV output, 3 SIP accounts with line switching support, MPLS, SIPS, AES, NAT traversal, H.264, 2X optical zoom, 30 FPS support, PIP, audio mute, camera block and more.

Music formats supported include AAC, MP3, WMA, Real and others. There is also language support for English, Chinese, Spanish, German, French and more on the way.

This is quite a phone in terms of raw features and we can expect to see these becoming a baseline phone for executives, knowledge workers and impromptu SMB conference areas.
