We chose OnSIP because it was a perfect fit for our small/medium size business with multiple locations. ... It feels as if everyone is working in the same location.

We wanted a phone system that was flexible and easily modular. We evaluated several providers and found OnSIP to be the most cost effective and feature rich solution.

That’s when I found my favorite part of the entire OnSIP experience - their tech support. With every call, they’ve been patient, friendly, and incredibly helpful. [They've] been there to answer every question and walk me through every process.

Intuitive Admin Portal, Comprehensive Support

It's our philosophy that you should be able to set up and test a service on your own, if you so choose. Our simple Admin UI, combined with our thorough knowledgebase articles, has enabled thousands of users to go from signup to testing features in a matter of minutes.

Of course, our US-based based support staff is always available to walk you through the steps or quickly help you get over any hurdles you may encounter in your team's implementation.

Patented Achitecture for Keeping Systems Online

Your phone service is a reflection of your business. It's important. That's why we use redundant servers, routers, Tier 1 Internet connections, and upstream carriers to provide an extremely reliable VoIP service.

Our platform is geographically distributed (patented) in 2 renowned data centers — New York and Los Angeles — to safeguard against a suboptimal event in a single location.We also route calls to avoid carrier hops whenever possible for maximum quality.

Pay per Minute or Per User - No Contracts

"One Size" does not "Fit All" when it comes to hosted VoIP. That's why we provide a few options for how you can pay for OnSIP.

Our Pay As You Go plan has been a differentiator in the industry, allowing organizations to add phones and users to their accounts at no cost - simply pay for how often the phones are used and add any additional features A La Carte.

For businesses with heavy usage or feature needs, our competitively-priced Per Seat Unlimited plan comes with a suite of features and all the calling you'll need, already included.
