To ensure a smooth experience with CloudTalk, we've provided a set of requirements device and network requirements here.

User Level:

  • System Administrator

You can also find useful information on network requirements within the following video, and even more helpful tips on our dedicated YouTube channel!


Device (dashboard application)

  • Minimum 4 GB of RAM (8 GB recommended)

  • Intel Core i5 / AMD Ryzen 5 processor

Our communications capability provider, WebRTC, is supported natively in most modern browsers. However, CloudTalk only officially supports Google Chrome. (Safari, Edge, and Firefox will also work but not all features are fully supported).



You'll need to make sure that you have enough bandwidth to support the number of simultaneous calls you expect your agents to make. The bandwidth used is up to 100 kbps per phone call.

  • Please note that this bandwidth only includes audio stream traffic for making and receiving calls.

  • Other applications (such as email or CRM) need additional bandwidth, so more headroom is required.

How much bandwidth? It's not possible to determine the exact bandwidth you might need, but 1 Mbps per person sharing the connection is a good start.


If your firewall blocks outbound connections by default, make sure to exclude any of our domains (* from inspection or policing on ports 80 and 443.

Read our QoS article to see our tables for configuring open network ports in your router, firewall, and antivirus software.

Suggested routers:

When possible, use a wired network connection. This will generally provide a more consistent and better quality network connection, which is vital for ensuring high call quality. We recommend using at least a Cat 5e Ethernet cable (ideally a Cat 6).

Suggested adapters (if no Ethernet port):


If you are using a VPN, we advise you to either completely deactivate it or do not use it while using CloudTalk.
