You can also erase any of your existing recordings associated with your voicemail box. To delete your name recording, unavailable greeting, or temporary greeting: Dial *98 on your OnSIP-registered phone. Enter your voicemail box number. Enter the PIN/password for your voicemail box. Press 0 for voicemail box options. Press 1 for unavailable greeting, 2 for your name, or 3 for temporary greeting. Press 2 to delete the existing recording on file.
Important note: If your file is not an mp3, do not change the file extension to "mp3". This doesn't make it an mp3, it makes it a fake mp3 and will cause serious problems.

You can change the global voicemail greetings for all the extension users or change voicemail greeting for a specific extension. A quick start guide for the administrator who is new to Yeastar S-Series VoIP PBX.
If your landline doesn’t have a way to save messages already built in, the best way to save that gorgeous message is with a recorder. But before you rush out to get it, don’t forget that most smartphones have a built in recorder. Try that first and see if it will pick up her voice loud and strong. It should save the message as an MP3 automatically, that you can send (via email or text) directly to your computer for safe keeping. If the quality is not great, then you can borrow a recorder or purchase one. We like the Olympus brand ourselves, because they save in MP3 and can upload to a computer wirelessly. We have the vtech phone/answering system indicated above. The outgoing message/greeting is of my young daughter’s voice and we would like to save it somehow. Am wondering if you have a process or can suggest how an outgoing/greeting message can be downloaded for safekeeping.
