Skype this week has added SIP support, essentially meaning that it's possible to integrate Skype calling with a business PABX. Potential VOIP call rates aside, a big selling point being pushed by Skype that companies can add a "dial us" link to their sites and allow customers to call them (for free) while maintaining their given telephone infrastructure. Personally, I hate this kind of click-to-call feature -- my first step after a Skype install is to disable the Skype Firefox extension, which otherwise mangles phone numbers every time you encounter them online. But I'm frequently not a representative human being. Would you like the ability to call companies via Skype direct from their site, or would you prefer a focus on other modes of communication?
