NetMeeting
You can place data calls through Microsoft NetMeeting.
NetMeeting data is transmitted via the network and is displayed on
the PC at each site. Data conferencing is only available during ISDN
(H.320) calls and must be supported by far-site systems.
Note
For more information about data conferencing, refer to Data
Conference on page 301 . This section also contains information
about how to use a ShowStation IP.
The following lists key information about data conferencing using
NetMeeting:
❑
To use the NetMeeting application sharing, file transfer, and
whiteboarding, your PC must be connected to your system via
your LAN.
❑
NetMeeting data is transmitted via the H.320 network. The
bandwidth used is dynamically allocated so that when
NetMeeting is not sending data, the bandwidth used returns to
the video data.
❑
System Compatibility and NetMeeting 3.0.
T.120 application
sharing, file transfer, and whiteboarding are supported for
NetMeeting 3.0 when used with two systems. You must have
the same version of NetMeeting installed on both ends of the
conference. These functions are not supported for NetMeeting
3.0 when used with a ViewStation EX system and a
videoconferencing unit from another vendor. In these
situations, you must install NetMeeting 2.11.
❑
Security Restrictions. For security reasons, the firewall will not
allow application sharing, file transfer, and whiteboarding in an
IP (H.323) call (on your system). Use NetMeeting to perform
these functions between two PCs once a connection to the far
site has been established.
❑
During the NetMeeting call, the whiteboard, chat, application
sharing, and file-transfer capabilities are available. Audio and
video are provided via the system.
