OnSIP makes setting up a phone system for your business like administering webmail. With a few clicks, you can add a phone number, users, phones, voicemail boxes, and more to your account.
 
But easy doesn't mean basic. OnSIP offers 50+ phone system features, hundreds of configuration options, and the freedom to use any standard SIP phones. OnSIP will grow with your business.
 
Reliability you can count on:
Your phone service is a reflection of your business. It's important. That's why we use redundant servers, routers, Tier 1 Internet connections, and upstream carriers to provide an extremely reliable VoIP service.
 
Our platform is geographically distributed (patented) in 2 renowned data centers — 60 Hudson St, New York, NY and One Wilshire Blvd, Los Angeles, CA — to safeguard against a suboptimal event in a single location. 
 
We also route calls to avoid carrier hops whenever possible for maximum quality. Today, customers connect to us via 600+ unique ISPs and are rarely more than a single hop away.
 
In addition to the OnSIP platform, you can rely on our people. You will have unlimited access to our U.S. based Customer Success Team, which holds a 98% satisfaction rating. We welcome you to connect with us on Twitter and Facebook.
