Note 43

In September 1981 John Goodhue took over from John Pershing the job of developing the Voice Funnel software.  Goodhue says, “The Voice Funnel was a gateway to the Wideband Packet Satellite Network for the experimental IP telephones and video conferencing stations being developed by DARPA packet voice community.   In addition to IP, the Voice Funnel supported ST - an early protocol for packet voice and video that supported call setup, resource reservation, conferencing, and other facilities that are now part of the standard Voice-over-IP stack. The Voice Funnel was the first application to be deployed on the Butterfly.  The first call through a Voice Funnel was made in 1982 between Lincoln Lab and ISI.”
