The access code for my voicemail is invalid after 5 years use. I inadvertantly deleted the voicemail phone number when seeking a solution to the invalid code problem. How can I get the voicmail number restored and get a new access code?

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.

To remove the voicemail indicator and stop the flashing light on your Panasonic home phone, you can try the following steps:
1. Access the voicemail system: Dial your home phone number from your Panasonic phone or another phone and let it ring until it goes to voicemail. Enter your voicemail password or follow the prompts to access your voicemail messages.
2. Listen to and delete all voicemail messages: Check your voicemail inbox for any new or saved messages. Listen to each message and follow the instructions to delete them. Ensure that your voicemail box is empty.
3. Exit the voicemail system: Once you have listened to and deleted all voicemail messages, exit the voicemail system by following the prompts or hanging up the call.
4. Reset the phone: Disconnect the power adapter from the back of your Panasonic phone base unit. Wait for about 30 seconds and then plug the power adapter back in. This will perform a reset on the phone and clear any residual indicators.
5. Check the voicemail indicator: After the phone has rebooted, check if the voicemail indicator is still active or if the light is still flashing. If the issue persists, proceed to the next step.
6. Disable visual voicemail feature (if applicable): Some Panasonic home phones offer a visual voicemail feature that may trigger the voicemail indicator and flashing light. To disable this feature, consult the user manual for your specific model and follow the instructions to turn off the visual voicemail function.
7. Contact Panasonic support: If you have followed the above steps and are still unable to remove the voicemail indicator or stop the flashing light, it's recommended to contact Panasonic customer support for further assistance. They can provide specific guidance based on your phone model and help troubleshoot the issue.
Remember to consult the user manual for your Panasonic home phone model as the steps and features may vary slightly.

Hi,

Once you call your voicemail service, you'll be taken thru step by step instructions to set up your voicemail.
To call your voicemail service

1. From the Home screen, tap Phone.
2. Touch and hold down 1.

If this does not work, you need to set up your voicemail number. Your subscription includes an answering service, callers can leave a voicemail message when you cannot answer a call. Usually, the voicemail number is saved on the SIM card. If not, contact your service provider to get your voicemail number. You can then enter the number manually.

Each mailbox password is held in the system programming of the voicemail system. You need the system admin password for voicemail. Dial the access code for voicemail, if from a phone with voicemail then press * to get to the main greeting. At the main greeting dial * then the system admin mailbox number which is 99 for 2 digit ext numbers or 999 for 3 digit ext numbers or 9999 for 4 digit ext numbers then you will be prompted for the system admin passcode(default 1234). Press 2 for add/edit/delete (Never press 1 for new installation or you could delete all current voicemail programming and messages). Press 2 to edit mailbox, you will be prompted for the mailbox to edit, enter the mailbox number. Press # to skip to the passcode reset, enter the new passcode or press * to reset to default(999) then press # for each of the remaining parameters until you are returned to the mailbox menu which prompts for press 1 to add mailbox, 2 to edit mailbox, and 3 to delete mailbox, then hangup.

also can reset factory settings on some but will lose numbers,messeges,etc.

Generally, you dial feature 981 to get in, then extension number and password. If you have no new messages it will say that, then give you the option to review old messages. To delete a message you press 76. If that doesn't work, login to your mailbox, press 8* then 6 to get to "go to message" then press the message number and #. If you have an on-site administrator, they can delete your mailbox as well, otherwise you will have to call your tech help service and have them erase it remotely.

If your wife never reset the codes when she used the phone, the "unlock" 4 digit PIN code is usually 1234, or sometimes the service provider resets it to the last 4 digits of your cell phone's number before sending it to you.
The SECURITY code is a 6 digit code which is set to "000000" when the phone is first sent to you and since your wife never used it that should still be it. I'd try entering 000000 for the "invalid security code" message you are getting and see if that does it. Some service providers may reset that security code before sending the phone to you too, so if any of those codes don't work you'll have to call your cell phone service provider to find out the codes. This info about all the codes was in my Razr V3 manual. Hope it helps.  If that does work for you and you can get into voicemail, then to reset the codes to your own personal ones go to ....Settings > Security > New Passwords and reset them.
If you get to the voicemail message screen and the message  stored there, (it's probably a message from the service provider) you have to call the voicemail number to retrieve the message, I just  press the keypad "dot" on the top right side under where it will say "call " and it dials & brings me to my voicemail.  The voicemail number should be stored in the phone, but because it was never set up you may have to call the provider to do so, I can't remember if it was already in there or not when I first set my phone up. Anyways......Good Luck & Happy New Year ; )

Use the super key again to program a speed dial key that dials the voicemails number. Instead of selecting 'clear' slect "change" and type in the number. To find the number of the voicemail, go to another phone and press their voicemail key and watch the display. It may briefly display the voicemial group number. You also can dial the voicemail number without the use of a button on your phone. But, you have to know the voicemail group number to dail it. Sorry i dont know the number to tell you, it could be anything that the installer decided to make it.
