No.  Asterisk only supports one "line/device" per registration.  i.e. 
Each "line" on the Cisco has an entry ("account") in sip.conf. 
Asterisk.  Asterisk sees each line as a seperate "device".

The issue happens when you want to use the same username/password for 
more than one line.  Can't do that (unless the phone has special support 
for only registering once for all lines, i.e. the Polycom).  Also you 
can't have more than one device register with the same username/password,
