Tips and Troubleshooting
Verify Component Interactions
Try a direct VIU-323-to-VIU-323 call to see if the problem lies with the gatekeeper.
1. Set up two VIU-323s to connect directly to each other rather than through the
gatekeeper.
2. Configure the VIU-323s to point to each other:
a. Run OnLAN Config 323 on a PC and specify the IP address of one of the
VIU-323s.
b. Advance to the Network Parameters dialog box and change the Default Gatekeeper
ID to the address of the destination VIU-323.
c. Save and transfer this configuration.
3. Make the same change on the destination VIU-323, specifying the source VIU-323's
IP address as the default gatekeeper.
4. Try the call again.
!
If the configuration works, the room system and VIU-323s are in order; the
problem is with the gatekeeper, which is either broken or configured incorrectly.
!
If the call still fails, check the default router IP address on both VIU-323s and
make sure they are correct. If this does not fix the problem, go to the next topic.
Eliminate the Network
Try a VIU-323-to-VIU-323 call with both VIU-323s on the same LAN segment to see if
the problem is within the equipment itself (if this is not possible—for example, if the
equipment is remotely located—skip to the next topic):
1. Set up the VIU-323s to connect directly to each other rather than through the
gatekeeper. This may involve moving one system onto the local segment. Modify the
IP address of the moved VIU-323 to a value appropriate for the local segment.
2. Configure the VIU-323s to point to each other:
a. Run OnLAN Config 323 on a PC and specify the IP address of one of the
VIU-323s.
b. Advance to the Network Parameters dialog box and change the Default Gatekeeper
ID to the address of the destination VIU-323.
c. Save and transfer this configuration.
3. Try the call again.
!
If this configuration works, the network is at fault.
!
If the problem still exists, it is likely that one piece of equipment has failed.
Selectively replace pieces of equipment and run test calls until you locate the
broken component.
