In many locations, it is a local or national requirement to warn those involved in a call that they are being recorded. One method for doing this is to enable the Advice of Call Recording (AOCR) message provided by the voicemail server.
The 'advice of recording' will always be played if the Advice of Call Recording message is enabled.
A caller may not hear an 'advice of recording' announcement when the call is using analogue trunks. Analogue trunks do not support call status signaling so the 'advice of recording' announcement is played as soon as the trunk is seized even if the call is ringing and has not been answered.
The Play Advice on Call Recording option is enabled by default.
