Using your cell phone to record a voicemail message isn't always easy. Between remembering what to say and getting the right timing, it's tricky. But your phone does have a playback option, and it's easy to listen to and review your message. For some people, though, cutting off the end of a message is a funny way to trick people and catch them off guard. In most situations, callers won't know it's intentional and will think you're far less than tech savvy. Definitely not an impression I'd want to make.
Greetings can be changed using any telephone, or from the Personal Communications Assistant using a desktop computer; However, departmental mailboxes and those assigned to labs and general spaces must be updated using a telephone.

Many busy businesses utilize auto attendant greetings to make a great first impression, however, if your business relies on the personal touch of a live receptionist, it is important to have a plan in place when that position is unstaffed. Make sure your voicemail greeting contains the useful information that your receptionist would normally provide. This could include: location & directions, office hours, website URL, or social media info, as well as any pertinent company information.
11. Howdy, you’ve reached [your name]’s cell phone. I will’t expend your name for the time being, but within the event you allow a short message, I’ll receive aid to you as hasty as that you just can be ready to assume.
