# Cloud Voice App Web Client Overview

The Cloud Voice App Web Client is a web-based client that runs entirely in your browser, so you can call, chat, and stay connected with your team without installing anything. It brings your calling, messaging, contacts, and meeting tools together in a single window, which makes it a quick way to get a user working without deploying desktop software.

:::note
The web client opens in a mainstream desktop browser. Officially supported browsers are Google Chrome, Microsoft Edge, and Opera. There is nothing to download or install: the user signs in with their extension credentials and works directly in the browser tab.

:::tip
Keep the browser updated to a recent version. Newer browser releases handle audio and video calling more reliably, which avoids one-way audio and connection problems that are otherwise hard to diagnose.

## The interface at a glance

The web client groups everything a user needs into one workspace. The image below shows the overall layout so you can get oriented before you start working.

## What you can do

From the web client a user can:

- Talk to coworkers and outside contacts in real time over audio or video calls.
- Message people one-on-one or in group chats, and share files right inside the conversation.
- Reach both the company's shared directory and their own personal contacts from one place.
- Launch a browser-based video meeting in a single click for fast, secure, face-to-face collaboration.
- Use the console to see who is available at a glance and route incoming calls without delay.
- Handle high call volumes efficiently, keeping response times short and customers satisfied.

:::note
Audio and video calls run inside the browser, so the browser prompts the user to allow microphone (and camera, for video) access the first time. If the user blocks these prompts, calls connect but no one can hear or see them. Grant the permission when asked, or re-enable it later from the browser's site settings.

:::note
The console shows each user's presence, meaning their real-time availability (for example available, on a call, or offline). Watching presence before you transfer a call lets you send it to someone who can actually pick up, instead of routing it to a busy or logged-out extension.
