VoIP Services Reviews
The most recent VoIP reviews say CallVantage outdistances Vonage and other competitors for consistently excellent call quality, as well as its menu of features (including call logs, voicemail, speed dial, call waiting/forwarding, caller ID, fax support, directory assistance, three-way calling, and do not disturb). Some reviews say installation could be simpler, but in tests, AT&T's customer service and technical support proved efficient at solving these issues. As of November 2005, about 35% of CallVantage subscribers didn't have E911 service (which automatically transmits your address to emergency personel), so you'll want to check before ditching your land line.
VoIP Of Quality with Assenment and Prediction Speech Quality of VoIP is an essential guide to assessing the speech quality of VoIP networks, whilst addressing the implications for the design of VoIP networks and systems. This book bridges the gap between the technical network-world and the psychoacoustic world of quality perception. Alexander Raake?s unique perspective combines awareness of the technical characteristics of VoIP networks and original research concerning the perception of speech transmitted across them.
Starting from the network designer?s point of view, the different characteristics of the network are addressed, and then linked to features perceived by users. This book provides an overview of the available knowledge on the principal, relevant aspects of speech and speech quality perception, of speech quality assessment, and of transmission properties of telephone and VoIP networks, and of the related perceptual features and resulting speech quality.

It's a nicely made cream/blue affair, about 10cm x 6cm, and won't look too out of place sitting on a desk or on top of a PC case. Three LED's on the front give status information, both on the units readiness and line status.
Assuming you have Skype already installed you just plug in the device using the supplied 50cm USB cable, drop the supplied CD-ROM into the drive and let Windows do the rest. It's a simple process, although you do need to put in your e-mail address at the final stage of installation
.Once you've authorised Skype to use the device you're ready to go.
