7105t voicemail button(#1) changed assignment
 

I would be able to figure this out if I had one to look at, but I'm still working with a 7290 and a user has the 7105t.

He says that now when he holds down the number 1 key to get his voicmail, it dials the last call he made.

Would anyone be kind enough to walk me through how to change this?

btw, awesome forums!
