Problem
The local and remote
sites cannot
communicate with
each other using site
numbers.
The local site cannot
place a call to a
remote site.
Issue 09 (2012-09-03)
Possible Cause
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.
The local or remote site is not
connected to an IP network.
The local or remote site is not
connected to an IP network.
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.
The gatekeeper with which the
local or remote site is registered
does not support the function of
placing calls using IP
addresses.
