Genesys Active Recording with CIM and Enhanced Passive Methods
Although Active Recording is the preferred recording method when integrating with Genesys, other techniques can also be used successfully.
Genesys Enhanced Passive Recording works by capturing SIP signaling protocol and RTP streams, and integrating the Genesys T-Server and Configuration Manager to get additional data about the calls.
Call Recording also provides direct support of Cisco Unified Communications Manager (CUCM) as a third-party PBX on the Genesys Customer Interaction Management Platform (CIM).
Finally, Genesys also supports recording via Stream Manager to create WAV files that can then be obtained by a third-party; however, Call Recording does not support this method, because it severely limits product functionality such as live monitoring, and provides no guarantee that the call will be recorded.
Active Recording of CUCM Integrated with Genesys CIM

In the Active (device based) recording method, Genesys CIM calls with CUCM, the Genesys (CIM) is deployed with CUCM as an underlying PBX.
In this scenario, the Cisco T-Server also performs integration. In addition to connecting to CUCM, Call Recording directly communicates with the Cisco TServer to get the call related data which is not available from the Cisco platform.
Enhanced Passive Recording EPR with Genesys CIM

The EPR method on the Genesys SIP Server tracks the SIP signaling protocol.
The Call Recording server monitors the SIP signaling and extracts information about calls currently in progress. This includes the terminal addresses of the parties involved in the call, and as a result, the recording server captures the RTP streams. Through the T-Library, Call Recording integrates with the SIP TServer to retrieve data about agents, their interactions, and any attached data.
This method is highly dependent on the network infrastructure.
