I need a user manual for my phone. Lucent 8410D

its likely your key is bouncing an needs cleaned or replaced . use a diffrent phone to be certain

Hi well Ok, in this case the BEST thing to do is to return it to "As from The factory" this will then reset it all and make it like a new phone, and is best done this way. So what you need to do is to perform a a factory reset. You will need to get the codes and program them in, this is quite detailed and this info is only available in the relevant manual, links below...

Please find a manual download links below, please use this manual to be able to perform what you need to do.

above is a command glossary too.
However IF you mean Voicemail password, then that can only be removed by contacting the service provider and getting them to do it, as it has nothing to do with a phone, as such.

hit the transfer button ,dial the extension of the other user and hit transfer again . or hit transfer and dial the voicemail extension and dial the voicemail extension of the other party and hit transfer

The Avaya 8410D set is a propriatary set which only works on a Avaya Definity system.

Hi,talking from experience,i will suggest you contact phone engineer in your area to carry out a check on the major components of your phone such as the earpiece,mouthpiece,LCD etc which might have been damaged(70%probability) as a result of the great shock experienced when it fell apart,
It won't cost me anything to give you the proper orientation of the hangup plunger wire,but you not knowing the orientation of this wire,which if i describe to you,you may end up doing it wrongly which poses a great risk or electric shock according to avaya,how are you sure some basic components have been installed properly by you.
So please take caution,contact a phone engineer in your area to assist you

Thanks and take care

Send all calls might be turned on

You should ask your phone system vendor for assistance in programming a button or enable a feature. Its not something we can help you on this forum

not sure if this site will help or not as I don't have this phone system, but maybe you can make sense of it.
Best of luck.
