What reviewers say

Reviewers overwhelmingly had a great experience with this company. Customers frequently praise the dedicated support team for their remarkably prompt responses, deep technical knowledge, and genuine willingness to guide users through complex system setups with absolute ease. Consumers consistently state that representatives are exceptionally kind, patient, and always accessible to provide clear, helpful solutions whenever questions or operational challenges arise during the day.
However, some people mentioned encountering frustrating technical difficulties, such as portal ticket submission errors, unexpected API problems, or sudden service disruptions without receiving sufficient advance warning from the staff. A small group of reviewers also noted occasional communication hurdles and restrictions that made it difficult to resolve specific account management issues promptly.

The customer service and tech support is fantastic!! 5 stars! The actual phone system has had some glitches that shouldn't be happening, like they will not work on our newer, faster internet service for the most part. And there are technical issues at the home "central station" every other month or so hurting the flow of business for hours on end. It only happens for a few hours, but we can't have that downtime. Otherwise, we are very happy with OnSip

Hi, Frank. I'll reach out via email to learn more about the issues you are experiencing. I'm surprised to hear it. -Joe
Their service has been next to flawless for us. We use OnSip in about a dozen locations and it's always been outstanding. Their prices are on the lower side and definitely less than the big players like RingCentral. What separates them from the crowded market of voice over IP providers is their North American base support. It's absolutely outstanding!
