This doesn't really help you, but might help others when deciding how to 
design their Asterisk system.  On our phones we set call waiting off and 
each line appearance registers as a separate SIP user.  This avoids all 
this silliness with call limits, group limits, etc.  This also allows us 
total control about which call appearance a call shows up on, roll over 
and hunting features, etc.  It does require a little more work in the 
dialplan, but for our needs it is well worth it.
