Disabling Mixed Protocols
The option Allow H.320 and H.323 Mixed Calls (Admin
Setup>Video Network>Call Preferences) allows the administrator
to disable the ability to place or received mixed multipoint calls for
security reasons.
This option is only accessible if the V.35 Video Calls or ISDN Video
Calls and LAN/Internet Calls options are both enabled on the Call
Preferences screen.
Telnet and FTP Timeout
There is a 30-second timeout when logging into FTP and Telnet. This
is intended to make the connection time out to free it in case the
login is unsuccessful.
