How to read this comparison
SIP accounts are registrations, not simultaneous calls. Programmable keys count assignable positions across pages, not just physical buttons. Conference capacity and encryption depend on firmware and configuration.
No is an explicit negative; Unknown means unresolved evidence; Not applicable means the field does not apply. An optional adapter is an extra accessory. Open Evidence for model scope, source sections and qualifications.
Differences keep your selected requirements and unknowns visible. Equal headline values can remain when their evidence notes differ.

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