Invalid feature and 2 lights lit

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.

I have been asked to advise, but sadly I am totally ignorant of the product,or its likely method of operation.

I wish you well, and I'm sorry that I cannot help or assist.

If none of your voicemail features are working(F980- F989) then somethings wrong with the voicemail itsself. Check to see if the power light is on inside the voicemail cabinet. If its lit, then try cycling the power on and off and wait abot 10 minutes to see if the voicemail comes back online.

Depending on the type of voicemail it can take up to 10 min, to fully come up. Is the power light lit in the voicemail cabinet? Also what kind of voicemail is it?

Unplug then replug. Works every time.

First off we need to know what color it is.

Green-Dial "0" from the problem phone and that should clear it.

Red-Dial "Feature 99 Feature". If that does not work.
Leave a message in that users mailbox. From that users phone check and delete that message.

If neither of these operations work then you may have a bad port which means you may need a new station card. The part is an ESI(8)-U10-ETU, ESIB(8)-U10-ETU or an ESIE(8)-U10-ETU. The U10 might be different.

Let me know how these options work.

This generally happens from one of two things. Your voice mail system is connected to your phone system through a station port. If it loses connection it will not communicate with the phone system. Loose wire or connection can cause this. or it has just crashed and will need repair or replacement.

First thing you want to do is unplug the unit wait 15 minutes and plug it back in. wait 10 minutes Try feature 981 from a set that has voicemail. if nothing. hit feature 985 from a m7310 set or a m7324 set not a m7208. If it comes back with inactive fearture now your connection between the units is bad or the unit itself is bad. If it comes back with the voicemail intercom # and you cant get into any mailboxes it has lost all programming.Try this first.

The system lost programming. Call a vendor in...
