I have a 7960G. It doesn't have six "lines," it can register with 6 
_proxies_, plus a backup, plus an emergency (the latter two don't have 
buttons.) Each of the six main proxies has it own "button." (You can 
register six times, with six different account, on the same proxy or six 
different proxies.) each proxy can accept two incoming calls, plus an 
outgoing call. You can also conference on the same "button" with the 
phone. You cannot (w/SIP 7.3) conference between proxies.

Before someone jumps up and "does the math" and says "it can handle 12 
incoming calls." Well, no. It can handle as many calls as your asterisk 
server can, but the user needs to use something like the "Flash Operator 
Panel" for Asterisk. Also, one or more of the proxies are often setup as 
"intercom" proxies (ie, they auto-answer and put the call on the speaker).
