Non-KX-T7400 cases
Whisper OHCA is activated when both calling and called extensions are using the KX-
T7400 series PTs by default. If either one of them is a non-KX-T7400 series PT, OHCA

However, Whisper OHCA between two non-KX-T7400 series PTs can be enabled by
System Programming < Section 2.8 System Option, "32. Whisper OHCA to extensions
other than T74/75XX>.
