something to do with caller id? Google Talk (VoIP) maybe?

click2pay is ramping up maybe ??

With a call entry? Looks more something like a Google Talk thing like Garret says. Nice find!

yes with a call entry .. that would be click2call and then navigation to the merchant for Q&A before you place your order via Gbuy!!
