Founded in 2004, OnSIP is a leading provider of real-time communications (RTC) services to over 45,000 businesses. OnSIP® Business VoIP customers enjoy the benefits of an on-demand phone system without the traditional high cost, burden, and inflexibility. The company also offers a cloud platform and simple APIs for developers to rapidly and affordably build RTC applications of their own. Sometimes we are asked, “Who is Junction Networks?” Junction Networks is our founding company name. OnSIP is our product/service. It just so happens that OnSIP is catchier, so we typically use it in most places!
