Is there any API to change calling party display name in a call? If not supported by JTAPI then is there any other Cisco API which support this.
Please Try CURRI - https://developer.cisco.com/site/curri/
CiscoRouteSession.selectRoute() API allows applications to change the calling party number. The call needs to be routed through a RP to achieve this. 'Name' is not supported. Application should have 'Standard CTI Allow Calling Number Modification' role to use this API.
