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. Review collected by and hosted on G2.com.
Sometimes the setup of the phones can be a hassle. I've struggled to get some of the Cisco phones to adopt to the network. Not sure if it is a hardware problem or a problem with the service. Review collected by and hosted on G2.com.
