OnSIP is a cloud-based business phone system that doesn't require any special equipment to install. The system runs on a high-speed internet connection. For optimal use, the company recommends 200 Kbps of bandwidth per call.
OnSIP uses redundant servers, routers, Tier 1 internet connections and upstream carriers to provide extremely reliable VoIP service. It also has two data centers – one in New York and one in California – to ensure the system is always up and running.
The entire system can be administered online. From the online portal, you can, among other things, add phone numbers, users, phones and voicemail boxes.
Access to the Sayso service is a unique offering that most business phone system providers don't offer. This can be a nice addition to your communication services if you are looking for improved ways for your website visitors to connect with your sales or support teams.
One downside to OnSIP is that you have to pay extra for the conference bridge. Most business phone system providers include this service in at least their upper tier packages. While being able to host calls with up to 15 people is nice, having to pay extra for it is not ideal.
Another downside is that the video conferencing only lets you host meetings with up to five participants. Having such a low limit on how many people can attend your video conferences might not suit your needs. If you plan to have meetings with more than four other people, you may have to invest in a separate video conferencing service, which would increase your overall communication costs.
