Transfer is a different CTI operation than a plain outside call. You should test this yourself to be sure but the Outbound on IPCC should be pure outbound calls, not transfers.
Detailed definitions are available in the reporting guide: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_6/user/guide/UCCX_BK_U89A45EB_00_uccx-historical-reporting-guide-106/UCCX_BK_U89A45EB_00_uccx-historical-reporting-guide-106_chapter_01.html#UCCX_RF_ACD33B1E_00
ACD - Transfer Out: Unified CCX calls that the agent transfers out.
Translation: of the calls handed to the agent from the RmCm subsystem, how many did the agent transfer elsewhere.
Outbound On IPCC - Total: Calls that the agent dials on a Unified CCX extension including both connected and attempted calls.
Translation: Total calls, attempted or successful, made from the agent's ACD extension (i.e. the one they enter into CAD/Finesse at login).
Outbound On Non-IPCC - Total: Calls that the agent dials on a non-Unified CCX extension including both connected and attempted calls.
Translation: Total calls, attempted or successful, made from any other DNs* on an agent's phone other than the ACD DN. *CCX only monitors the first four line appearances; if an agent has a 796x or other phone with more than four PLKs/DNs then those extra line appearances beyond the first four will NOT be included in this number.
