Instead of using CTIOS Toolkit which looks like it is COM based. Is there a web service api document that you can use to code your own .net client for Cisco CTI?
Cisco Advanced Services offers a Web Services interface to CTIOS. The CTIOS Web Service provides a SOAP XML web method call interface to the CTIOS Server. It's use will require the customer or partner to develop an application that implements the CTIOS Web Service WSDL. This can be done with just about any programming language available which supports HTTP and SOAP XML constructs.
You have to reach out to your cisco Services Account Manager to get more info.
Here is the doc link which talks more about this in detail:
Let me know if this answered your query.
I suppose Cisco Advanced Services to get Web services interface to CTIOS will add cost to both vendor and customer or is it completely free?
