I'm looking for help with querying UC Manager nodes for information on
currently parked calls. A customer wants to integrate this information
into an internal application but I'm not sure how to get it (in real
time) out of UC Manager.

Specifically they need:

-Park DN
-Parked by DN
-ANI of call
-Timestamp of when call was parked
-(Optional) Original DNIS if this is not overwritten when parked.

I'm hoping this is possible with the XML Serviceability interface
but I don't understand SOAP enough to read the WSDL and know what I can
get back from UCM. If I can get a definitive answer on whether this is possible and the general idea of how, I'll get it to the customer's devlopers and they can take it from there.
