Hello I have a little problem. I have WCF Service and 3CX Phone System with VAD. My task is to connect with database through WCF Service and pass some data to the caller. But when I try to connect with WCF via Web Services Interaction component there is an error: 415 Unsupported Media Type. So my question is - is there any way to configure WCF to handle this component properly? I have also tried External Code Execution component - I wrote simple dll to connect with my service but there is another problem - Phone System couldn't find app.config with endpoint declared. For now I am out of ideas :S Does anyone knows how to configure this properly? Thanks in advance.
