A professional voicemail should be short and succinct. Simply introduce your company, ask the caller to leave their information, and let the caller know when to expect a callback. Once you record your greeting, you can easily upload it into the OpenPhone app. Simply go to your phone number’s settings, then choose to record a greeting, upload an mp3 file, or use text-to-speech.
Please note there is a new rule regarding the posting of videos. It reads, "Post a summary of the videos you post . An exception can be made for music videos.". Unless you are simply sharing music, please post a summary, or the gist, of the video you wish to share.

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.
