Intro and renewal prices
For introductory cost, OnSIP lists entry access at $18.95. That starting figure is the stated point for beginning paid service and helps small business teams frame monthly budgets around a clear entry level rather than an uncertain range. For renewal cost, the same listed point at $18.95 is the stated price reference, without a separate renewal schedule shown in the listed facts. There is no Free plan available, so continued use moves through paid access after any trial review. That structure favors shoppers who prefer a defined entry price plus a trial window over an ongoing free tier with tighter feature limits.
The company behind it
OnSIP is associated with Junction Networks and is based in the United States. Origins date to 2004, which places the service among long running business calling providers rather than recent market entrants. That history can matter for small business buyers who value continuity in service, documentation, and customer care. Support is available through email, phone and help centre, combining direct phone and email contact with a help centre for self guided answers. Together, the company setting in the United States, the link to Junction Networks, the start in 2004, and access through email, phone and help centre give a clear picture of who provides the service and where to turn for help.
