The property value is of type BOOL and specifies whether the phone call is on hold.

Remarks

If you set the KSPROPERTY_TELEPHONY_CALLHOLD property with a value of TRUE, the phone call will be placed on hold. The expected behavior is that both transmission and reception will be muted. No data will be sent or received in this case. The audio driver will update the call state (TELEPHONY_CALLSTATE) to TELEPHONY_CALLSTATE_HOLD. If you set the KSPROPERTY_TELEPHONY_CALLHOLD property with a value of FALSE, the phone call will be taken off of hold state, and the call state will be updated to TELEPHONY_CALLSTATE_ENABLED.
