OK.  The following assumes that your phones have 4 phones with 2 lines a 
piece.

Phone 1: 5000, 5004
Phone 2: 5001, 5005
Phone 3, 5002, 5006
Phone 4, 5003, 5007

Adapt it as you choose.

It will ring all four phones at a time.  If "line 1" of a phone is busy, 
it will ring line 2 of that phone.  This is off the top of my head and 
hadn't been tested on my asterisk server but, I'm pretty sure it will 
work.  I have a few lines set up in this manner.


[extensions]
exten => 
s,1,Dial(LOCAL/5000 at extensions&LOCAL/5001 at extensions&LOCAL/5002 at extensions&LOCAL/5003 at extensions,20,tr)

exten => 5000,1,Dial(SIP/5000)
exten => 5000,2,hangup
exten => 5000,102,Dial(SIP/5004)

exten => 5001,1,Dial(SIP/5001)
