That aside, this also appears to be a SIP based phone service that uses the CounterPath X-Lite softphone.
2006 will be the year of the SoftPhone. Yahoo’s new Messenger-especially the enhanced new Mac version that is being built from the ground up, the PhoneGnome SoftGnome, Popular Telephony’s Peerio, EyeBall and more all are in the pipeline or out with initial versions that I have seen.
QoS will thus become more important as more people make AND receive calls on PCs and other new endpoints.
