HUAWEI VP9050 Executive Video Terminal
User Guide
Problem
After startup, the
terminal cannot be
registered with the
gatekeeper.
After defining a
conference on the
terminal, a
conference cannot
be initiated.
Issue 03 (2011-12-10)
Possible Cause
The settings used for
registration with the
gatekeeper are incorrect. In
other words, GK address,
H.323 ID, or Password is set
incorrectly.
Contact the administrator of
the videoconferencing system.
Check whether a site using the
same user name as that of the
local site has already been
registered with the gatekeeper.
Access the Line Status screen
to check whether the IP
network is disconnected.
The NAT settings are
incorrect. If the local site is in
a private network and if the
gatekeeper is in a public
network, check whether the
local site can communicate
with the gatekeeper properly.
If not, the local NAT settings
are incorrect.
The listen port of the
gatekeeper (such as port 1719)
is restricted by the network
firewall.
The terminal is not connected
to the videoconferencing
network.
If the local site pays for the
conference, check whether the
account balance of the local
site is sufficient. If another
site pays for the conference,
check whether the
corresponding account
number and password are set
correctly and whether the
account balance of the site is
sufficient.
