What is Vonage?
Vonage is best known for two things: a solid mid-market phone system (Vonage Business Communications) and a deep CPaaS API platform that lets developers embed voice, SMS and video into their own apps.
Now owned by Ericsson, Vonage operates a tier-1 global voice network and serves more than 100,000 businesses. For most buyers, the conversation is about Vonage Business Communications (VBC) — its UCaaS phone system — and Vonage Contact Center (powered by NewVoiceMedia, which Vonage acquired in 2018).
Where Vonage really differentiates is the API layer. If your business plans to embed click-to-call, programmable IVR, SMS notifications or in-app video, very few competitors match the depth of Vonage's developer platform.

Vonage frequently asked questions
Is Vonage good for small businesses?
Yes — Vonage Business Communications scales from 1 user upwards, and the entry-level Express plan starts at £10/user/month excluding VAT (checked Oct 2026). Smaller teams typically don't need the CPaaS layer.
Does Vonage integrate with Salesforce?
Yes. Vonage Contact Center is built natively on Salesforce, and Vonage Business Communications offers a CTI integration for click-to-dial, screen pops and call logging.
What is the difference between Vonage and RingCentral?
Both are mature UCaaS platforms. Vonage stands out for its CPaaS APIs and Salesforce-native contact centre. RingCentral is generally considered to have a more polished day-to-day UX.
Does Vonage offer AI call answering?
Yes — via Vonage AI Studio, a low-code builder for virtual agents that can handle inbound calls, qualify leads and route to a human when needed.
