asterisk users - Jan 2005 - simulating multiple lines using ADSI

Does anyone have any experience with making an
adsi phone appear to have more than one line.
It seems like this would be a very simple and very useful
thing to be able to do.  Ideally, it would be nice if you
could make the 6 soft buttons appear as lines 1-6 and
if you press one of the soft buttons, it puts the current
line on hold and gives you a new dialtone.

Has anyone either done something like this or would
happen to know how to do something like this?


Thanks,


Jon.
