DeviceCommand value

Hi,

I am developing a custom CTI driver and defined a command "MyMakeCall" in Administration-Communication. Command parameters are as -

Description                This is to invoke CTI command

Hidden                       TRUE

DeviceCommand       MakeCall

1. While configuring CTI, I have chosen business service as "Communication Client"

2. Added a new button in CTI Toolbar.

3. Configured a Command named MyMakeCall in Administration Communication as shown above.

4. Till this point button is disabled and the tool tip displayed is "This is to invoke CTI command" as configured above.

5. This means the button is properly linked with the above command.

6. I have the doubt if the DeviceCommand value MakeCall
