Comment: Updated WebRTC destination media ports to ephemeral range

Firewall configuration

...

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 are processed in a timely and efficient manner (call steering buttons, call transfers, hold requests, and so on).

...

SFTP access to call recordings requires TCP port 2244044.

Inbound

All inbound traffic requires access to destination TCP port 443 (HTTPS) on our servers to establish a connection. Responses are sent to a range of ephemeral ports.

...

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