What category of Genesys Cloud CX phones is solely supported by the BYOC Premises VoIP deployment model?

The category of Genesys Cloud CX phones that is solely supported by the Bring Your Own Carrier (BYOC) Premises VoIP deployment model is Unmanaged phones.

Unmanaged phones are those that are not provided or managed by Genesys, meaning they do not receive configuration or updates through the Genesys Cloud platform. Instead, customers must configure and manage these phones independently in their on-premise environment. This is particularly relevant in the BYOC Premises deployment where enterprises leverage their existing on-premises voice infrastructure while using the capabilities of Genesys Cloud.

In contrast, Managed phones are directly supported and configured via the Genesys platform, ensuring that they receive updates and settings automatically, which differentiates them from the Unmanaged category. WebRTC phones rely on web technologies for real-time communication and do not require a physical VoIP setup, while Remote phones typically refer to remote workers using managed devices without the specific premise-based configuration associated with BYOC. Thus, the alignment of Unmanaged phones with the premise-based setup of BYOC is what makes this category the correct answer.
