This parameter sets the default for all sessions using that Speech Server. Setting wcr_encrypt in the session.xml file or setting the SIP header P-Nuance-WCR-Encrypt overrides the setting of server.rtp.wcr.encrypt for the current session only.
The system stores whole call recordings files with the call logs. Encrypted recordings have an added extension .enc.
