OnSip is a great VOIP service. We are very happy that we can manage every scenario for callers and employees without breaking the bank, and the customer service is fantastic.

David Kretch

From the time I found out that my small business needed a new phone system to the time that we were up and running with OnSIP I could not have asked for a better transition.

Kayren Ohnhaus

The system is flexible and easy to use. We really appreciate the quality of the service and are getting so many great features for way less money than our old phone service.  It is great!
