[Asterisk-Users] Line appearances

[Joseph]

I am trying to get an understanding of how line appearances work
like on the cisco 7960 phones.

Is there a wiki somewhere about how this works?

Also, the 7960 phones let you register more than one ext.
Why would you want more than one or is this connected to line
appearances?

Is there a way to have phones use more than one codec, say
use g.711 to talk with * and g.729 to talk with another
phone?
