The VTAS service has now been retired (May 2017). In a new partnership with Ajenta, Jisc are planning the next evolution of the Vscene videoconferencing service. As part of this change Jisc has decided to retire the VTAS service. The content below is part of the VTAS archive. The Janet Video Technology Advisory Service (VTAS)  provides unbiased technical advice on equipment and issues related to videoconferencing. Product evaluations are published via this web site for all of the Janet community to access.
