Dear, is it possible that integrate UCCX8.5 with Salesforce ? Now Salesforce has some integrated conditions:
 1 CTI system must support middleware of standard COM components
2 the COM components must support C++ COM Event Sink
3.COM component must be able to provide users in the CTI integrated process requires the CTI passed to the Salesforce.com application of various information parameter. ( such as recording file address, CTI telephone recording ID, IVR parameters and other information) - according to customers requirements.
 4.COM component can be initialized in silence by a caller interface , as required in the interface case can be active to initialize COM component cannot be realized Salesforce.com CTI integration.

Thank you David.
