Hi,
In order to use the telephony SDK (CWIC API), you will need a user, line and device of type CSF ("Cisco Unified Client Services Framework"), same as Jabber for Windows but with a different name. By default the SDK expects a device with name ECPuser, where user is the CUCM end user name. See more info here
