Overview
In some cases, organizations that utilize Boostlingo for voice and video interpretation services will need to adjust their organization’s firewall configuration to allow for connectivity. This guide presents domain names, port openings, and IP address exceptions that will need to be added to the organization’s firewall configuration for Boostlingo voice and video services in the United States and North America.
Domain Names
If adding URL-based exceptions to your firewall to allow traffic to/from Boostlingo for platform usage and voice/video services, the URLs (web addresses) listed below would need to be added:
For Boostlingo’s platform:
- app.boostlingo.com
- d3b9k3gd90kchk.cloudfront.net
For Interpret Manager:
<your_branded_subdomain>.interpretmanager.com
For Boostlingo voice/video services:
- us-prod.service.signalr.net
If using Mobile voice/video services in the US:
- onesignal.com
IP Address Ranges / Ports
An organization may elect to use IP-based exceptions with coordinating ports in the organization’s firewall for connectivity to applications and services external to the organization. Below are the IP address ranges and ports that will need to be added to the firewall exceptions list for connectivity to Boostlingo’s voice & video services.
To access Twilio, your firewall should allow outgoing TCP and UDP traffic from your applications to Twilio’s infrastructure and allow return traffic in response. Twilio will never initiate a connection to the SDK applications. Therefore, the firewall should not allow externally initiated connections back into the network.
