When I dial 440 to get to the voicemail, it just rings and I cannot get to the administrative mailbox. I need troubleshooting tips please.

The "10B1" message on your Panasonic KX-TGD390C phone may indicate that your voicemail box is still full, even if you've deleted all the messages. This could be due to some saved or undeleted messages in a different folder or some other issue with your voicemail settings. To clear your mailbox and resolve this issue, you can try the following steps:

1. Access your voicemail box: Dial your voicemail access number. It's typically a number provided by your phone service provider, such as "123" or "555."
2. Follow the voice prompts: Once you're in your voicemail system, listen to the voice prompts carefully. There should be an option to manage your messages or change your mailbox settings.
3. Delete all messages: Even if you've already deleted messages from your phone, there may be some messages still stored in your voicemail box. Use the voicemail system's options to delete all messages.
4. Check saved messages: Some voicemail systems have a separate folder for saved messages. Make sure to check this folder and delete any saved messages if they exist.
5. Change mailbox settings: If you cannot find any messages in your voicemail box and it's still showing as full, you may need to access your mailbox settings and reset or reconfigure them. Look for options related to mailbox size, message retention, or other similar settings. You might need to contact your service provider for assistance if you can't find these settings.
6. Reboot your phone: After you've taken the above steps, it's a good idea to power cycle or reboot your Panasonic phone. This can sometimes help refresh its connection to the voicemail system.
7. Contact your service provider: If you're still experiencing issues after trying these steps, it's a good idea to contact your phone service provider's customer support for assistance. They can help you troubleshoot and resolve any voicemail-related problems.

Remember that the specific steps and options may vary depending on your phone service provider and the voicemail system they use. It's essential to follow the prompts and options provided by your voicemail system when you access it through your voicemail access number.

Voicemail is usually ext 200 or 300 if it's not assigned on a speed dial button. If your ext has a mailbox assigned the voicemail will greet you or ask for your code. If you don't know the code your voicemail administrator will have to reset the password or mailbox. If your ext doesn't have a mailbox assigned, then it will just give you the main greeting that outside callers get.
