Administrator Guide
Problem
Your site cannot place a call
to a remote site using the IP
address of the remote site.
After the endpoint starts, it
fails to register with the GK.
Issue 01 (2016-09-01)
Possible Cause
The local or remote
endpoint is not connected to
an IP network.
NAT settings are incorrect.
Specifically, the local
endpoint is on a private
network while the remote
endpoint is on a public or
different private network.
Check whether your
endpoint can communicate
with a public network. If the
endpoint cannot, NAT
settings are incorrect.
The GK with which the
local or remote endpoint
registers does not support
the function for placing calls
using IP addresses.
The parameters (GK
address, encryption
password, and user name)
used for GK registration are
incorrect.
Another site with the same
number as your site has
already registered with the
GK.
