Kevin,

	I posted a message earlier regarding this, here is the SIP debug output 
(forgive the wrapping) of using the "Park" softkey:

The header I was looking for is:

Refer-To: sip:callpark at pbx.kcdemo.com;orbit=401

How is that XML?  It looks fairly easy to parse.  It may not be a 
NOTIFY, but SipGetHeader appears to be in the right direction...

Granted the ACD stuff may be XML, but I am SO not there yet...  I 
haven't even looked at it.
