Adding password to voicemail number?

[jetnc]

Since my fdr I just noticed had a voicemail and when I went to hear it noticed I had to enter my password...argh...

Can someone set me straight on how to set this up again?

I noticed I had 2 numbers on the voicemail contact, 1 labeled mobile and the other home with my password. But I'm not sure how make one priority I guess

I refined my search and found the answer......sorry but I should have looked harder.
