Compatible phone systems

The indicator shows whether a compatible configuration path is documented, or whether the result still needs verification. A not-listed result does not mean technically incompatible. It does not replace checking the provider firmware branch, tenant, network and feature requirements.

3CX V20Not reviewed

Listed firmware applies to 3CX V20. Cloud or remote phones need a router phone or SBC. Recheck the current provider release before deployment.

Zoom PhoneNot reviewed

Yealink phones require Zoom-specific firmware. A certification entry does not confirm every feature or regional deployment.

Microsoft Teams SIP GatewayNot reviewed

This is SIP Gateway compatibility, not native Teams-phone certification. Use the gateway provisioning path and approved firmware; confirm tenant licensing, policies and network requirements.
