Since you ask this question under a Partner 18D, the answer for a Partner system is you go to extension 10 or 11 and, without picking up the handset, press FEATURE 00 and the left intercom button twice. Then for time you dial #103 and the 4 digit military time. Date is #101 and MMDDYY.

FEATURE 00 exits programming.

Mute the speaker, mute the ringing?

Press Feature 00 (zero, zero) from station 10 or 11. Press left intercom button twice, press #103, and then enter time in military format (24 hr). Press feature 00 again. This is all done with the handset down.

Avaya Partner 18D Button phone:
Two possible solutions,
First, could have a bad handset cord.
Second, I have come across a bad handset connection ports on the Euro style phones. The handset cord and the port just don't mesh well or the port itself is bad.

That one doesn't sound too good.
You could perform a reset through programming which should clear the scratch pad.
Thats done by entering programming on either ext. 10 or 11
Press feature 00 then the left hand intercom twice.
Next enter # 728, the display should say reset save all then reboot the system.If the problem is still there, then the processor is malfunctioning and will need to be replaced.

It is not possible to diable the speaker phone but you can use the HFAI / Mute button to mute or unmute the spk. By default the spker phone is muted. Hope this helps.

You need to figure out what voicemail you have first? When you dial into voicemail, what does it say? Welcome to Partner Mail, partner mailVS, Partner voice messaging or partner messaging.

it makes all the difference in the world.

A simple Google search found a manual covering the Avaya (Partner) 18d phone.

Good luck.

Try hitting the speaker button and intercom your boss. When you hit the speaker button to hang up, do you get the same thing? If not. It could be that the gray "clicker" switch that pushes down when you put the handset back isnt going all the way back down...

Let me know.
