Hello, this is Susan. I don't live here, so if you were trying to call me, you've dialed the wrong number. On the other hand, if you were trying to call John, Jim, or Eric, please leave your name and number at the tone. I don't guarantee that one of them will call you back -- only that I won't.
Different businesses may require different types of greetings. This is the ultimate list that can work for a wide array of company messages.

04You have reached the offices of [your company/business]. Our representatives are all currently engaged. If you leave us a message with your name and number, we will get back to you in the earliest possible time. Thank you for calling and have a good day. Lines can often get busy for companies that have several representatives. This reassures clients that someone will get back to them once they are free.
And I think if you just want to add like let's say you want three numbers instead of four, because that's the next pricing point is four numbers instead of two. You can add a number at any of these levels for just $4 a month. So if regardless of which level of Vumber you have and you just want an extra number over and above what your account allows for bucks gets you a free number or get you a $4 number, all right, back to the script. So that's the way Vumber works. You can press pound and it skips the rest of the message and goes right to the beep.
