How do you change the answering machine message?

This come from a previous model than I have (mine is a ol5870), but seems to work for this one in retrieving messages from another phone.

Default access code is 0000 if you haven't changed it (but you should); when answering machine answer dial in the 4 digit code while the outgoing message is playing.

Once in dial 1,2, or 3 to play messages (mail box number I believe)

You can dial * for a help menu

4 Repeat a message
44 Ignores a message (message won't remote retrieve next call)
6 plays next message (skip to next)
7 Deletes message
8 Lets you record a memo
9 Let's you change the outgoing message (5 stops the recording)
0 Toggles answer on/off

I hope this helps some people at least in part.
