Running Global Management System
How do I calculate Greenwich Mean Time offset?
Click on date and time in the control panel on your computer. A pull down menu will state 
what the GMT offset is at your location.
What is the posting frequency from the video endpoints?
Video endpoints does not auto post to Global Management System at a specific interval.
Instead the video endpoints posts information whenever it receives a request from Global
Management System. For example, a user clicks on the Call Status tab, which causes the
video endpoints to post call status information.
When the server address is entered, the browser page appears with an HTTP 404 error.
The browser cannot find the default web page. Default website location may not properly 
set. On IIS, check the path on the Default Website properties for the correct location. It 
should be “drive:/Inetpub/wwwroot”  where Global Management System web folders are 
stored under.
Why can’t I access the web interface of ViaVideo but can with a ViewStation through the 
Manage System feature of Global Management System?
ViaVideo must be password protected before Global Management System can access the 
web interface. By default, ViaVideo does not have password protection enabled. To set the 
password in ViaVideo, navigate to System info > Global Services > Global Management 
in the ViaVideo web interface. On this page, there is a Web Access Password field. 
Once a password is entered, this unit’s web interface can be accessed through Global 
Management System when the login in information is filled in through the Manage System 
feature. 
What is “Other” device type and how to use it?
“Other” device type can be any web server that supports HTTP. What is required is the 
ability to understand HTTP web request. For example, Sony® Contact 1600 has a web 
server which can be monitor by using “Other” device type. When adding using “Other” 
device type, user specifies the IP address, the port, and the HTML file (if it is not the 
default.htm file). Global Management System will be able to detect whether the system is 
online or offline based on the response string of that device. 
Does Global Management System work through the firewall?
This depends on the setup of the video network behind the firewall. As long as the IP 
address of the managed endpoints aren’t translated through NAT (Network Address 
Translation), port 80 (HTTP), port 21 (FTP), and port 3601 (GAB protocol), Global 
Management System will function properly. Some firewall policies don’t allow request 
outside the firewall to be made. If this is the case, Global Management System can’t 
manage the endpoints inside the network. It is then required to have policy change to 
allow TCP request from the Global Management System server.
