Call Status
How can my video endpoint be in a call when the line status shows a red arrow pointing 
down?
If the video endpoint is configured to use both IP and ISDN, it can still make IP calls 
even if the ISDN line is down. Also, Global Management System shows the red arrow 
in the system list whenever any of the ISDN lines is down. Therefore, a video endpoint 
configured to use four ISDN lines (512K) could have one line down, and yet still be able to 
make a call using the remaining three ISDN lines (384K).
Video endpoints do not display the in-call icon when they are in a call and sometimes 
display the in-call icon when not in a call.
This is usually caused by having an incorrect Manager URL. Select a video endpoint and 
click on the Management tab to view the Manager URL. Make sure that the IP address 
shown is the one used by your Global Management System server. If it is different, you will 
have to re-install Global Management System to change the Manager URL. This can also 
be caused by video endpoints trying to send status information to a Global Management 
System server behind a firewall. If Global Management System is trying to manage a 
video endpoint outside the firewall, be sure that the firewall allows bi-directional traffic 
between them on port 80.
Some of the video endpoints display line-problems when all of their lines are working 
soundly.
The Manager URL is not correctly entered in the video endpoint.  Select a video endpoint 
and click on the Management tab to view the Manager URL. Make sure that the IP 
address shown is the one used by your Global Management System server. If it is 
different, you will have to re-install Global Management System to change the Manager 
URL.
After I change my server IP address, Global Management System shows a yellow network 
status icon for all video endpoints.
This is cause by mismatch between actual Global Management System IP address and 
the address on the video endpoint Global Management System URL. Don’t change the 
server address after installing Global Management System. When this happens, you 
will have re-install Global Management System and add all video endpoints into Global 
Management System again. Always use static IP address when assigning it to Global 
Management System server.
