Firewall configuration

In this section


You must read this entire section to ensure that you configure your firewall correctly.

We recommend adding the appropriate URLs and IP addresses to any firewall rules that restrict employee access, and we request that you treat Vonage Contact Center as a business critical application. By this, we mean optimizing and prioritizing IP traffic to Vonage Contact Center over other non-critical traffic. This is to ensure real-time responses to agent requests (call steering buttons, call transfers, hold requests, and so on).

You should also review any IP packet inspection or local caching policies to optimize the user experience.

All inbound and outbound traffic requires port 443 (HTTPS). SFTP access to call recordings requires port 22.



Using URL allowlisting (recommended)

Add the following URLs to your allowlist:

You must also add the IP addresses specified in the following sections to your allowlist:



Using IP allowlisting

If your firewall does not support URL or DNS allowlisting, add the following IP addresses for your region to any existing firewall permissions.

Outbound VCC traffic

Outbound IP addresses are used for standard web access, for example, agents and supervisors accessing Vonage Contact Center applications. All customers will need to allow this.

If your firewall does not support URL/DNS allowlisting, add the following IP addresses for your region to any existing firewall permissions:
