H.323 Tunneling

The tunneling feature relies on H.225 system-to-system connectivity (via TCP) to pass H.245 messages,
and uses the H.225 communication channel without creating a separate TCP socket connection (per H.323
call) for media control. H.323 tunneling is supported by the video conferencing system. To use H.323
tunneling, make ensure the participants in the call enable H.323 tunneling simultaneously. When you log in
to the StarLeaf platform or use an H.323 account, you can configure the H.323 tunneling feature.
Description
Configure the port of the
H.323 call signaling.
If you fail to place an IP call
to other party via H.323
protocol, it may be caused
by the ISP limiting the 1720
port, so you need modify the
protocol monitor port, and
call the far site by dialing
h323:ip:port.
Note: the default value is
1720. The modification on
this port is only applicable for
the H.323 IP call.
Enable or disable the local
early media feature on the
device.
• Off—the local system
sends an Open Logical
Channel (OLC) message
and receives the
acknowledgement
message of OLC from the
far site. After receiving
the acknowledgement
message, the system may
transmit RTP streams to
the far site.
• On—the system sends
an OLC message to the
far site and then transmits
RTP streams to the far site
directly before receiving
the acknowledgement
message of OLC. For
some gatekeepers, you
need to enable this feature
to avoid black screen
during a call.
Default: Off.
