VoIP Providers & Business Phone Companies in Campbell, CA

8x8, Inc. is a publicly traded provider of cloud-based business communications, listed on Nasdaq under the ticker EGHT. The company is now headquartered in Campbell, California, having moved from its earlier Santa Clara base. It sells hosted voice, video, chat and contact center technology to organizations that want to replace on-premises phone equipment with a service delivered over the internet. Buyers comparing local technology dealers should note that 8x8 is a large vendor with a worldwide footprint, not a small installer.

The company's roots in this category go back a long way. It was founded in 1987, and its early business phone offering aimed to replace traditional private branch exchange systems for small businesses with an internet-based alternative. Over the years the offering has grown from that small-business voice service into a broader cloud platform. It now serves organizations of many sizes, and it reports operations in several countries, including the United States, the United Kingdom, Romania, Australia, Singapore and Portugal.

What the company offers

For a business looking at VoIP and unified communications, the portfolio centers on one platform that combines several channels. Public materials describe the following capabilities:

• Cloud business phone service delivered as VoIP
• Video meetings and team chat for staff in different locations
• Contact center software for handling customer conversations across channels
• Workforce management tools for agent visibility, which the company made available to customers at no extra cost in 2025
• Communications platform as a service, which lets developers build voice and messaging features into their own applications
• Jitsi, an open-source video conferencing brand that the company owns

Because these functions run on a single cloud platform, a buyer can start with business calling and add collaboration or customer-facing contact center features later, without managing separate systems at each office.

How it works with customers

8x8 operates as a service provider. Customers subscribe to the platform instead of purchasing and maintaining a phone system on site. Its own materials stress reliability, security and scale, and it has historically paired the technology with a customer support organization and distribution partners. Staff can use desk phones, mobile devices and computers, which suits distributed and remote teams. The company publishes a leadership team led by CEO Samuel Wilson and reported annual revenue of roughly 736 million US dollars for 2024, which gives buyers some sense of the vendor's size and stability.

The company continues to expand. Its about-us page notes a 2026 acquisition of Maven Labs, intended to speed up innovation and growth in Asia. This points to continued investment in the product and in international markets, which matters to buyers with branches or customers overseas.

Who it suits

The service fits small and mid-sized businesses that want hosted telephony. It also fits larger enterprises that need a contact center and unified communications from one vendor. Companies that prefer a local installer to visit and cable an office may want to ask whether a regional reseller or partner can provide on-site help alongside the 8x8 platform. Those that are comfortable with a remote, subscription-based model will find a mature, long-established provider with a broad product range.
