HUAWEI 9000 HD Video Terminal
Administrator 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 09 (2012-09-03)
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.
