What is network-based recording (NBR) or "Record on Server"?
Network-based recording (NBR) is a recording option available to WebEx
customers on release WBS25 or later. Network-based recording enables you to
capture all meeting content, including WebEx integrated audio, VoIP audio, or
third-party audio conference for later playback and sharing. NBR recordings are
saved to WebEx high-availability storage servers, making it easy to access all
Unlike the stand-alone WebEx Recorder for WRF format files,
network-based recording is managed completely within the WebEx client and does
not require the use of additional hardware, such as a phone recording adapter

editing capabilities through your WebEx service site, without requiring the use
a video-editing application.

I cannot play my network-based recording file on the latest WebEx
Network Recording Player after my site was upgraded. What should I do?
Starting in WBS28.9, a new audio engine was introduced in the WebEx
Network Recording Player, and an old audio codec was removed. Due to those
changes, network-based recording files (.arf) that were created on a release
earlier than WBS27.12 (earlier than March 2010) and use VoIP-only audio can no
longer be played on the latest Network Recording Player (they can still be
played on earlier versions of the WebEx Network Recording Player).
Network-based recordings that use VoIP-only audio and that were created after
WBS27.12 can be played on the latest release using the new player with no
issues. Network-based recordings that use hybrid audio (mix of VoIP and
telephony or telephony only) are not impacted. If you still have access to an
older version of the Network Recording Player, you can convert your recording
file (.arf) to standard video format such as Windows Media File (.wmv) format,
Flash (.swf) format, or MPEG-4 format (MP4).
The WebEx Network Recording Player does not support converting
recordings to MP4 format on Mac systems.
