## Browser support

Voiso works best in the latest **Google Chrome** browser. Google Chrome is the only browser officially supported for the Voiso application, Agent Panel, and Agent Omnichannel Workspace.

          Tip

          

Voiso recommends that users keep Google Chrome up to date. When an outdated version is detected during sign-in, Voiso allows the user to sign in, but displays a message recommending that the user update Google Chrome.

Using the latest version of Chrome ensures compatibility with Voiso features and current security standards.

          Important

          

Voiso allows users to sign in using an unsupported browser. However, a warning message is displayed recommending that the user switch to Google Chrome for the best user experience.

## Supported hardware

You can use Voiso on [desktop or laptop computers](/v1/docs/system-requirements#recommendations) running a [supported operating system](/v1/docs/system-requirements#supported-operating-systems) and has the latest Google Chrome installed.

### Recommendations

- 4GB RAM (8GB recommended)
- Dual-core processor
- Minimum screen resolution: 1024 x 768
- Microphone and speakers or headset with microphone

## Supported operating systems

Voiso runs best on the Google Chrome browser in Windows, Mac OS, and Linux. Voiso recommends running the latest version of the operating system, but up to 2 previous versions are supported.

### Mobile

The Voiso web experience is not supported on mobile devices; however, the [Voiso Mobile app](/v1/docs/download-the-mobile-app) is supported for both Android and iOS devices.

## Network requirements

The Voiso contact center URL should be on your network *allow list* for outgoing and incoming connections.

### Recommendations

- A DNS server configured to resolve the Voiso domain names to IP addresses. For example, you may configure the primary DNS to 8.8.8.8.
- Avoid connecting to your Voiso contact center using a VPN.

### Bandwidth

Voiso recommends a minimum of 1 Mbps down/up or better.

## Security

Voiso recommends you configure your firewalls or any proxy services on desktop computers or laptops to allow specific port ranges when you are using the Voiso platform.

### WebRTC

- **Signaling**: TCP/443 for IP address corresponding to your contact center name ({contact center name}.voiso.com)
- **Media**: UDP source ephemeral port range, destination static port range 10000 - 20000

Note

Ephemeral port range depends on the OS typeand version and the version of Chrome browser you use.

### Hardware/Software phones

- **Signaling**: UDP/5060 for IP address corresponding to cluster ingress gateway (agents.{cluster name}.voiso.com)
- **Media**: UDP source ephemeral port range, destination static port range 10000 - 20000

Note

Ephemeral port range depends on Hardware/Softphone configuration.

### IP Addresses

You can manage the list of IP addresses from which users may log into your contact center by enabling **Restrict access to specific hosts/subnets** on the **Security** tab of the [System settings](/v1/docs/administration-system-settings) page, then configuring the hosts and subnets on the **[Allowed hosts/subnets](/v1/docs/administration-allowed-hosts-subnets)** page.
