Fantastic US-Based Support Team Makes All the Difference

Their US-based customer support team is EXTREMELY responsive, knowledgable, understanding, and helps empower me to problem solve and find solutions on my own; they're also more than happy to help with quick fixes or issues where it is, in fact, user error or I'm missing something. Very patient, considerate, educated, and ready to solve the problem immediately.

Quality Service, Affordable Price

OnSIP is a fantastic service. The pricing cannot be beaten for phone service. We are using the service in a small manufacturing facility. I've managed the IT department of a similar sized organization and we were paying 10 times as much using a traditional phone service. The support team is very responsive. If you have an issue or a question, reach out to them. They respond right away. The service supports a wide range of IP phones. We are using Cisco phones on the network and they work great. When we needed to add a cordless phone, we were able to add one by a different vendor and it works great.
