Troubleshooting methods for the problems that arise during conference control
Problem

Solution
The local and
remote sites cannot
communicate with
each other using site
numbers.
The local or remote site is not
registered with the gatekeeper.
In this case, the local site
cannot translate the site
number of a remote site to the
corresponding IP address
using the gatekeeper.
Therefore, calls cannot be
placed to the remote sites
using the relevant site number.
If a remote site places a call to
the local site and if the
gatekeeper provides a message
indicating that the local site is
not registered with the
gatekeeper, the call cannot be
set up.
Check the registration settings, and
then re-register with the
gatekeeper.
The local or remote site is not
connected to an IP network.
Check the IP network settings and
the connection of the IP network
cable. Ensure that the settings are
correct and the cable is connected
properly.
The local site cannot
place a call to a
remote site.
The local or remote site is not
connected to an IP network.
Check the IP network settings and
the connection of the IP network
cable. Ensure that the settings are
correct and the cable is connected
properly.
The NAT settings are
incorrect. If the local site is in
a private network and if the
remote site is in another
private network or in a public
network, check whether the
local site can communicate
with the remote site. If not,
check whether the NAT
settings are correct.
Access the screen for setting NAT
parameters, and then set the
parameters properly.
The gatekeeper with which the
local or remote site is
registered does not support the
function of placing calls using
IP addresses.

at the local and remote
