Microsoft now joined the VoiP race. This summer Microsoft will release not a Windows software but a VoIP System to be called Microsoft’s Response Point Small Business VoIP system. There will be a Service Pack to Response Point which will add SIP (Session Initiation Protocol) trunking and click-to-call. This service pack is for phone systems that run its Response Point communications software for small businesses. This Service Pack 1 for Response Point will add the capability to the Voice over Internet Protocol functions. Microsoft said that this system will not only provide patches to the VoiP system but new features and functions as well.
