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:

LocationIP addresses

Australia

54.252.254.64/26

Brazil177.71.206.192/26
Ireland54.171.127.192/26
52.215.127.0/24
Frankfurt 35.156.191.128/25
Japan 54.65.63.192/26
Singapore 54.169.127.128/26
US East Coast (Virginia) 54.172.60.0/23
34.203.250.0/23

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.

...

The URLs of our data centers with corresponding IP addresses are shown in the following table. The You must add the appropriate IP addresses must be added to any existing firewall permissions.

...

Inbound IP addresses are used when NewVoiceMedia interacts with an external system where IP white-listingIP whitelisting is in place. Such systems include Salesforce; a customer owned, or managed, server or service; and other cloud provider services.

Application acceleration

To improve performance and response time, we use a content delivery network (CDN) for some of our NewVoiceMedia applications. Your firewall must allow requests to and from cdn.newvoicemedia.com for supervisors and agents to access NewVoiceMedia applications. If your firewall does not support URL whitelisting, you must whitelist the IP addresses listed at http://d7uri8nf7uskq.cloudfront.net/tools/list-cloudfront-ips.

Note

The list of addresses at http://d7uri8nf7uskq.cloudfront.net/tools/list-cloudfront-ips is subject to change.
