Understanding the network requirements

There are several services that must be allowed so that they're accessible in your
network:



Contact Center services: Contact Center leverages AWS Cloudfront to
host and serve Contact Center. To reach the Contact Center SaaS-hosted
services, your network must be able to reach the associated IPs.

Customer-deployed services: Contact Center leverages the AWS API
Gateway as part of the Cloudformation stack deployed and hosted in your AWS
environment as a customer. The API Gateway service leverages an EDGE type
API gateway.

Additional third-party services: Zendesk leverages a number of
third-party services for extended functionality, including analytics,
user-metrics, and beta feature toggling. To ensure you have access to full
Contact Center functionality, you should allow the domains and IP addresses
of the services you use.
