Firewall configuration

Your firewalls should allow UDP to and from the public internet for the browsers that will be using ContactPad with WebRTC.

NewVoiceMedia's WebRTC servers use fixed IP addresses from a public range. The WebRTC client uses Global Low Latency (GLL) architecture. GLL reduces the latency of calls by selecting the closest IP address for WebRTC, but includes failover to another IP address if the closest one is not available. We recommend that you configure your firewall to allow all of the following IP addresses to prevent loss of service in case of failover:

For Global Low Latency and ResiliencyAdd all of the above IP addresses as recommended

NewVoiceMedia WebRTC servers use dynamic port numbers. We therefore strongly recommend that your firewall does not limit access to a specific range of port numbers for those IP addresses.

Supported browsers

Google Chrome™, latest version, using the WebRTC for NewVoiceMedia extension.

Note

We develop and test the WebRTC feature in the latest version of Google Chrome™ only.


Salesforce integrationWebRTC is only supported in Salesforce Lightning Experience and in the console view in Salesforce Classic. For information about Salesforce console, see Salesforce help.
Backup phoneAll agents should have access to an alternative phone as a backup for WebRTC.
Alternative phoneWe recommend that agents have access to an alternative phone for non-NewVoiceMedia related calls.
