Vonage cloud-hosted voip phone

What’s a cloud-hosted VoIP phone system?

VoIP stands for Voice over Internet Protocol. That means your office phone system will run over high-speed internet and connect your IP network to the cloud. A VoIP office phone service that’s hosted in the Vonage Cloud is feature-rich, reliable, efficient, and affordable and can be an integral part of either a small business phone system or a mid-sized/enterprise phone solution.

office phone system features

Get the features you need. Only where you need them.

Every phone number extension on your Vonage® office phone system starts with a standard suite of 40+ features included. Additional, premium features can be added per extension or across the entire account. That means the business services of your lobby extension and your CEO’s extension don’t need to have the same capabilities or costs.

business continuity for office phone systems

Communication is the lifeblood of your business. Interruptions are not an option.

Vonage customers who choose a small business plug-and-play phone system can start calling within hours of purchase by downloading our mobile app or desktop app.

We also have expedient solutions for Enterprise needs. Enterprise customers can utilize existing broadband with our BYOB solutions or SIP trunking.

coworkers experiencing QOS across multiple devices

Optimal bandwidth. Any network.

Quality of Service (QoS) is an industry-wide set of standards used to ensure high-quality performance for critical applications which, in the case of an office phone system, includes voice and other unified communications. QoS is achieved when these communications functions have sufficient bandwidth, latency and jitter are controlled, and data loss is reduced. With SD-WAN solutions, our customers gain optimized bandwidth and enhanced QoS that minimizes call drops, data loss and static.
