Requirements

Web browser support

Voice for Browser is tested and validated for latest stable version of Google Chrome browser on Windows 11.

Audio support

Audio input and output is required, i.e. microphone and speakers.

Network requirements

When a Firewall is running rules “inside-to-outside”, traffic from Clients to Enreach data center needs to be allowed.

Please note the same also possible workstation level firewall solutions.

Enreach server side never initiates connections towards Voice for Browser clients. If customer is using stateless firewall it must be ensured that return traffic from Enreach servers to originating source ports is passed through.

Quality of service

The connection between Voice for Browser and the Enreach data center is routed via public Internet. To ensure needed call quality make sure that the Internet connection of the client network has enough bandwidth. Under heavy load, prioritizing audio traffic (SRTP) is recommended. If priority queuing is used for audio traffic, enough bandwidth must be configured for the priority queue. DSCP marking should be done on network level devices. Workstation clients are not DSCP-marking RTP traffic .

The bandwidth requirement of one concurrent voice call is 100 kbps
