Correct.  Asterisk does not support multiple logins from the same SIP 
username.  HOWEVER, if you configure the same SIP username/secret on all 
6 lines of a Cisco (or Polycom) the PHONE will NOT register using the 
same username/secret more than once.  It will see that more than one 
line is using the same username/secret and only register once.  This is 
specific to the phone in question.
