Agreed. We got this to work, however, the documentation leaves you wanting more. For example, the explanation of the various greetings -- vdn, ani, auto-answer, manual -- if very light.

Workplace already supports greetings https://documentation.avaya.com/bundle/Planning_Administering_Avaya_IX_Workplace_Client_Android_iOS_Mac_Windows/page/Greetings.html

Primarily this will assist us in meeting state law that requires the recording that states "this call will be recorded" be recorded with the call. The secondary affect is consistence across application/devices.
