I purchased this VoIP speakerphone to talk with friends using my computer.
You are instructed to download Skype first, then install the disk, connect
your TVP-SP2 and complete the process.
When installing the phone, you are notified there is a more recent version
of Skype available, and asks if you want to install it. DO NOT. The disk
will install v2.5 of Skype. The current is v4.0.0.226 which you already
installed per TRENDnet's instructions prior.
The correct default audio device to use is USB Audio Device in XP Control
Panel, Sounds and Devices, OR you will disable the PC speakers, and audio
plays thru the TVP-SP2 speaker instead. The 3.5mm jacks for installing the
headset of your choice frees a USB port, and the audio quality is good. A
external 5VDC power supply adapter is an option, but not critical because
the TVP-SP2 uses the 5V source of the USB port to function.
So far it seems to work well w/Skype, and will try it with Yahoo Messenger
next. Using w/Microsoft LifeCam NX-3000 and the video works. You can keep
the display lit holding down the # key, and the LCD display does give you
good status and connection indicators. Skype has low-cost calling features
which can connect you to landline and cellphones around the world when you
set up an account.
I recommend the TVP-SP2 for cost, ease of use and installation (above) and
the extensive features and options available using Skype with it. It seems
compatible with my XP SP3 using a cable broadband connection. You cannot
use this for dial-up, not enough bandwidth for the application to run and
you definitely need high speed for a videocam to work, if you want to use.
