Hi Rich;

   It is not a Cisco format. It is part of the Internet
protocol, RFC 2250

http://www.ietf.org/rfc/rfc2250.txt

It was not developed by Cisco, and is supported by many
major players such as RealOne and Apple Quicktime.

I would be glad to help you get your system format into the
Internet protocol, although it will be tough going if it is
not carried by RTP.

Regards
Marshall
