Call Status
How can my video endpoint be in a call when the line status shows a red arrow pointing down?
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.
Some of the video endpoints display line-problems when all of their lines are working soundly.
Polycom ReadiManager LX100 User Guide
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, ReadiManager LX100 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).
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
ReadiManager LX100 server. If it is different, you will have to re-install ReadiManager LX100 to change
the Manager URL. This can also be caused by video endpoints trying to send status information to a
ReadiManager LX100 server behind a firewall. If ReadiManager LX100 is trying to manage a video endpoint
outside the firewall, be sure that the firewall allows bi-directional traffic between them on port 80.
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
ReadiManager LX100 server. If it is different, you will have to re-install ReadiManager LX100 to
change the Manager URL.
