Why does the port range 16384-32767 (RTP media) need to be opened up for Genesys Cloud Voice/BYOC Cloud?

IMMEDIATE ACTION REQUIRED: To ensure the business continuity of your Genesys Cloud organization, read the entire 2024 Genesys CIDR expansion and firewall requirements notification article and then run all applicable tests to confirm your organization’s readiness for the new CIDR IP address range and the RTP port expansion.

This port range only needs to be opened for outbound connections. Genesys Cloud needs access to all of the ports in this range to ensure that the number of possible simultaneous media streams is sufficient. If these ports are not open for outbound connections, then any media that uses RTP may be intermittent or completely unavailable.
