OnSIP provides scalable, cloud-based VoIP and WebRTC communications for SMBs, offering flexible pricing and a developer-friendly platform for modern businesses.
OnSIP, an Ooma company, is a leading provider of cloud-based business communications designed to serve small to medium-sized businesses (SMBs) and distributed teams. Established in 2004 and headquartered in New York, OnSIP was a pioneer in the hosted VoIP space, focusing on leveraging the Session Initiation Protocol (SIP) to deliver high-quality, reliable voice and video services. In 2021, OnSIP was acquired by Ooma, Inc., a move that integrated OnSIP’s sophisticated web-calling technology with Ooma’s extensive telecommunications infrastructure and market reach.
The vendor’s core offering is a comprehensive Unified Communications as a Service (UCaaS) platform. This includes a full suite of PBX features such as auto-attendants, ring groups, call recording, and voicemail-to-email, alongside modern collaboration tools like instant messaging, video conferencing, and screen sharing. OnSIP is particularly well-regarded for its WebRTC-based solutions, which bridge the gap between traditional telephony and web-based interaction.
OnSIP serves over 100,000 customer accounts, ranging from small startups to established professional services firms. Their market presence is defined by a reputation for reliability and a "no-contract" approach to service. By focusing on open standards, OnSIP ensures that its customers are not locked into proprietary hardware, providing a level of future-proofing that is highly valued in the rapidly evolving digital workplace. Today, as part of Ooma, OnSIP continues to innovate at the intersection of web technology and business telephony, providing scalable solutions that grow alongside their clients.
Company Differentiation
What sets OnSIP apart as a company is its commitment to "developer-centricity" and transparency within the telecommunications industry. Founded in 2004 and now operating as an Ooma company, OnSIP maintains a culture of technical excellence, rooted in the belief that business communications should be as flexible as the web itself. Unlike traditional carriers that operate as black boxes, OnSIP has historically championed open standards and open-source contributions, particularly in the SIP and WebRTC communities.
Their business model is uniquely customer-aligned, offering a "pay-as-you-go" pricing structure that is rare in a market dominated by rigid per-seat monthly contracts. This reflects a company philosophy that prioritizes utility and fairness over guaranteed recurring revenue. Their approach to customer success is deeply technical; support teams are known for their ability to troubleshoot complex networking and SIP signaling issues, providing a level of expertise that goes beyond basic script-based troubleshooting. As part of the Ooma family, they combine the agility and specialized focus of a boutique provider with the financial stability and infrastructure scale of a major publicly traded telecommunications leader.

Product Differentiation
The OnSIP product suite is built on a geographically distributed "super-plug" architecture that eliminates the single points of failure common in traditional PBX systems. A primary technical differentiator is their early and deep integration of WebRTC (Web Real-Time Communication). While many competitors treat the web browser as an afterthought, OnSIP’s platform allows businesses to treat their website as a communication endpoint. Features like "sayso," their proprietary website voice and video chat tool, allow visitors to initiate high-definition calls directly from a browser without any downloads or plugins.
Another significant product differentiator is the "OnSIP App," which serves as a comprehensive softphone for mobile and desktop, integrating seamlessly with their cloud PBX. Their platform supports an extensive range of hardware, maintaining a "bring your own device" (BYOD) philosophy that allows for easy provisioning of various IP phone brands. Furthermore, OnSIP offers a robust API and developer toolkit, enabling companies to embed real-time voice and video capabilities directly into their own applications or workflows. This flexibility, combined with high-definition audio codecs and an intuitive administrative portal, makes the product particularly attractive to tech-forward companies that require more than a "one size fits all" telephony solution.
