Prepare your organization’s network for Azure Communication Services
This article summarizes how the network environment affects voice and video calling quality. Many factors contribute to the quality of Azure Communication Services real-time media that includes audio, video, and application sharing. Some of the factors include network quality and bandwidth, firewall, host, and device configurations.
Network quality:
The quality of real-time media over IP is significantly affected by the quality of the underlying network.
Network bandwidth:
Ensure that your network is configured to support the bandwidth required by concurrent Communication Services media sessions and other business applications. Testing the end-to-end network path for bandwidth bottlenecks is critical to the successful deployment of your multimedia Communication Services solution.
Firewall configuration:
Communication Services connections require internet connectivity to specific ports and IP addresses to deliver high-quality multimedia experiences. Without access to these ports and IP addresses, Communication Services can still work. The optimal experience is provided when the recommended ports and IP ranges are open.
Network optimization:
The following tasks are optional and aren't required for rolling out Communication Services. Use this guidance to optimize your network and Communication Services performance or if you know you have some network limitations. You might want to optimize further if:
Communication Services runs slowly. Maybe you have insufficient bandwidth.
Calls keep dropping. Drops might be caused by firewall or proxy blockers.
Calls have static and cut out, or voices sound like robots. These issues might be caused by jitter or packet loss.
