Cannot download voicemail as WAV file, error: vm-error-evt

When the Unified Messaging service starts on the Mailbox server, it will verify that all the system prompts are available. If a system prompt can't be found, Unified Messaging will return an error. To fix the error that is returned, locate the event using Event Viewer and copy the file listed in the Event Properties window from the installation DVD into the appropriate folder on the Mailbox server.

After you install the Mailbox server and create a UM dial plan, you have the option to use the audio files for the default system prompts that are created during installation or to create customized audio files that can be used with UM dial plans. UM dial plans have a welcome greeting and an optional informational announcement you can modify.

The welcome greeting is used when an Outlook Voice Access user or another caller calls the subscriber access number. The callers hear a default welcome greeting that says, "Welcome, you are connected to Microsoft Exchange.

Unified Messaging allows for an informational announcement to follow the welcome greeting. By default, there is no informational announcement configured. However, you may want to provide one for callers. You can use the informational announcement for general announcements that change more often than the welcome greeting or for announcements required by corporate compliance policies.

When it's important that the whole informational announcement is heard, you can configure it to be uninterruptible. This prevents a caller from pressing a key or speaking a command to interrupt and stop the informational announcement. When you are customizing and configuring greetings and announcements, make sure the language setting configured on the UM dial plan is the same as the language of the custom prompts you create.

If not, a caller may hear a message or greeting in one language and another message or greeting in a different language. As with UM dial plans, UM auto attendants have a welcome greeting, an optional informational announcement, and an optional custom menu prompt. You can check these settings for yourself using the Phone app on your device. This app and its settings menu will look slightly different, depending on your device model and Android version.

The voicemail settings shown here should be applied automatically when you insert a SIM card into your cell phone, but they could have become corrupted or outdated. You may believe that your voicemail settings are correct, but there can sometimes be conflicting settings on your cell phone that can cause issues with voicemail not working on your Android device.

To help overcome these issues, you can request new settings from your carrier to set up your voicemail. How you do this will depend on your carrier and location. You may also be using a visual voicemail service that allows you to view voicemail messages in a list to listen, save, or delete using a voicemail app. The best way to manually update these settings is to visit the website for your network carrier for additional information or to contact your carrier directly.
