Not directly. Unfortunately, the user programmable voice file is reserved for your Auto-Attendant greeting, so the Leave-a-Message service greeting cannot be changed.
However, if you really need a separate voicemail greeting, then just get another Flextel number, set it to voicemail and record your own message. Now set this Flextel number as then destination of the Auto-Attendant ICD.Yes, simply get another Flextel number and list this new number as one of your menu options.
(Tip: To go to voicemail, if no key is pressed then set the radio button, next to it.)
Your greeting is repeated up to 3 times. If a caller fails to respond within this period, the call is ended. This is to avoid callers being over-charged if they forget to end the call.
Alternatively, you can decide to send unresponsive callers to one of your extensions. Just go to the Auto-Attendant Menu and click the radio button on the right of the preferred extension (under "No Key Press?"). Now if callers fail to respond to your menu, they are connected to your chosen extension. This can be voicemail.
