In Call Queue, when selecting "Redirect this call to" Voicemail and selecting "Type in a greeting message." It plays the message I typed in then it says, "Please leave a message after the tone, when you have finished, please hang up." Unlike Auto Attendant there is not an option to "Suppress voicemail system message". On the other hand, when you select "Play an audio file" it does not play the system message.
Is there a way to suppress the system message via Powershell? Seems odd that it would suppress the message one way but not the other.
Also, does anyone know why when transferring from an Auto Attendant to a Call Queue, it takes 8 seconds to hear the next message or hold music, but when you transfer to another Auto Attendant it only takes 3?
