Well, thank you to Tor for the SetGroup/Checkgroup config.  It works 
well!  (Thanks to John for the contexts/dialplan version, too).  
Unfortunately, the phone doesn't audibly ring when the second call is 
coming in (just a visual prompt), and you have to press the line 
appearance button, and then the Answer softkey to actually pick up the 
second call, but I think it is still an improvement over the Call 
Waiting (at least logically, for my receptionists).

Kevin, I think you are right that disabling the call waiting on the 
phone itself is the best idea.  Unfortunately, after hours of pouring 
through the config files and trying a million settings, I haven't 
gotten anything to work.  The "divert" section that you pointed out, 
Wiley, I think is just for forwarding calls for various conditions (I 
thought about trying to make a call forward to a second registration 
for a busy, but I think the phones don't register a busy signal on a 
line unless both "call waitings" are already active -D'Oh).  I thought 
I'd better ask the makers directly, though, so I filled out the online 
support form on the Polycom website.  If we're lucky maybe we'll get an 
answer.

Thanks Again for all the help,
Noah
