Hello Kavin,
you can find callrecording name doing the following:
set a brakepoint in the CL _IC_CAD_DATA_PROCESS, method GET_CMS_DATA on:
* Parse the CAD and transfer into an internal table
IF lv_string IS NOT INITIAL.
look into lv_xml_string what information consists.
On the SAP CCtr side you can look through OII logs in the Integration_VU, set log lvl to trace before.
BR,
Anton.
