Correct Answer: Review the media resource and any intermediate devices (such as gateways, conference bridges, or CUBE) in the call path to confirm each supports and is configured for SRTP, since a non-SRTP-capable intermediate device could prevent end-to-end media encryption despite both phones supporting it
Explanation: Reviewing intermediate media path devices for SRTP support is the appropriate diagnostic step when signaling is secure but media is not encrypted, unlike blaming ringtone assignment, replacing hardware immediately, wrongly assuming deprecation, blaming office lighting, or blaming the phase of the moon.
