In some situations where devices including phones and gateways are registered to different servers within a cluster, the devices registered to one Cisco CallManager are unable to call via devices registered to another Cisco CallManager.
Use the following procedure to troubleshoot this issue.
- Check the IP connectivity between the devices that you are attempting to call.
- Study the Route Plan Report and ensure that the route plan is perfect.
- As this problem can also arise due to the inconsistency in the database between the publisher and subscribers within the cluster, consider resetting the Cisco CallManager service on the publisher.
Resetting the Cisco CallManager service on the publisher re-runs the snapshot agent which syncs the database to all its subscribers and fixes this problem.
Note: Resetting the publisher affects all the devices registered to it. Plan for a scheduled down time and reset the service.
