None of these have yet to emerge into enterprise space just yet; however, each has huge corporate backing that could dramatically shift focus. At the time of publication of this book, Google and eBay had announced an agreement to provide "click-to-call advertising functionality on eBay and Google sites in the United States and around the world" (http://www2.ebay.com/aw/ core /200608280311132.html).
Newer click-to-call applications enable a potential consumer to click an advertising link to be connected to a salesperson through any online VoIP application. The eBay/ Google deal will enable Google Talk and Skype to be used for such advertising links so advertisers can reach out to consumers with a higher degree of personal touch. As online advertising marketing analysts suggest, it's highly likely that some of the other IM softphones will move into the click-to-call space as well.
Instead of a phone number as shown in Figure 10-9, VoIP click-to-call applications will ask for a Messaging ID, such as a Skype or Google Talk ID.
