Just press the button and you’re on to the next call while the software is recording your pre-recorded voicemail on the other line. Be sure to plan and practice your message. You want it to sound natural and enthusiastic without seeming overly excited or solicitous. You also want to make sure it doesn’t go on too long.
It may sound silly, but the tone in which you say something can either play the professional status up, or it can bring it down. You can’t change what your voice naturally sounds like, but you can work on controlling it to make sure you sound calm and collected when recording your message.

What's better than one of these not-so-funny voicemail messages? A voicemail greeting that's well written and professionally recorded. The most important thing to remember when writing a new voicemail is don't waste the caller's time. A concise, informative voicemail may seem "square," but its better than irritating and alienating potential business opportunity.
If you would like to assign a Voicemail entry to your Main Account, please from your main portal refer to Main Menu -> Account Settings -> General -> Voicemail Associated to the Main Account. If you need to assign a Voicemail to a specific subaccount, you need to go to the Sub Accounts Edit page, following the route, Subaccounts >> Manage Subaccounts >> Edit, from the menu tabs. You will see at the bottom of the page the "Internal Extension Voicemail" option. Here you can set it.
