I need to program the speed dial buttons on an Avaya 4412D+

Which system is this on? Could be Merlin Magix or Avaya IP Office.

To select a ring pattern for your telephone press: EXIT + "lift handset button" +
# 0 0 + EXIT + starbutton 3 2 + ring (choose ringtone 1 - 8 ) then press # "star" 0 0 to set
ringtone. There is only possible to change the ring pattern, not the sound it self.

You can not. What are you trying to do? Restrict the phone so no one can call out? What system is this on?

To program your Personal Speed Dial numbers, make a list of
your telephone numbers/extensions numbered 1 to 24, then:
Press an Intercom button + lift handset + dial #00 + dial # + list number (01 to 24) + dial *21 + the number you want to store + #*00.

To use Personal Speed Dial:
1: Press an Intercon button.
2: Press Feature (if you have programmed a "Feature" button) or #.
3: Dial the two-digit code (01 to 24).

I don't think the voice mail is going bad.

On my 4424D+, I can turn off voice mail.
I use this feature when I'm gone for an extended period of time so I don't come back to 100 VMs.

Dial into your voice mail.
Choose the prompt for Call Answer Mode. (Option 8 on my phone.)
Then choose the prompt for Record Mode. (Option 1 for me.) This allows callers to record voice mails on your line.

What phone system is this on?

While the handset is on hook,
1. Press "Program" 2. Press the desired Speed Dial botton 3. Enter your to-be-stored phone number 4. Press "Program" to end the session.

To program a speed dial for an outside line: Pick up the handset, press #00, press the button to be programmed, press *21, then enter the number to be dialed (including any dial out number and areacode).

To program a speaad dial for in internal extension: Pick up the handset, press #00, press the button to be programmed, press *22, then enter the ext to be dialed.

(Once you hit #00, you can also follow the screen prompts).

press speaker 00
press the button you want to program
press *56
Press the speaker button.

Label your button

The Avaya website (www.avaya.com) is loaded with manuals, you just have to know where to look.. Here's one http://support.avaya.com/elmodocs2/partner_acs/r7/518457701_2.pdf

Page 13 tells you how to program a button (ie FEAT 00 button dial the number and press FEAT 00 again to exit). Page 16 tells you how to program personal speed dial number from the 20 bins 80-99 allotted to your phone.
