The Cisco IP Voice Media Streaming Application service provides voice media streaming functionality for Cisco Unified Communications Manager for use with Media Termination Point (MTP), conferencing, music on hold (MOH), and annunciator. The Cisco IP Voice Media Streaming Application relays messages from Cisco Unified Communications Manager to the IP voice media streaming driver, which handles Real-Time Protocol (RTP) streaming.
The Cisco IP Voice Media Streaming Application service does not generate the Call Management Record (CMR) files for call legs that involve any IP Voice Media Streaming Application components like conference, MOH, annunciator, or MTP.
