Assuming you are using SIP handsets, distinctive ring isn't directly an 
Asterisk feature. Rather, you must consult the documentation for your 
endpoints, and determine how to signal them to use a different ringer. 
Usually it involves a SIP header. For an example, I use snom 870 
handets, and I have this in my dialplan:

SIPAddHeader(Alert-Info: 
<http://notused.example.com>;info=sales;x-line-id=0)

and I've also configured the handsets to associate "sales" with "Ringer 3".
