CMS High Availability helps reduce the potential loss of External Call History Interface (ECHI) data sent to the ECHI server because if the primary CMS server is no longer functioning, you can start ECHI on the secondary CMS and continue to collect data.
If you do not use customized CMS reporting solutions developed by Avaya APS, ECHI data should be administered on only one CMS server at a time.
If you do use customized CMS reporting solutions developed by Avaya APS, consult with your APS representative for details about how to manage ECHI operations on the two servers.
If your ECHI installation is not usually running concurrently on both CMS servers, you may decide to switch External Call History data collection from the primary server to the secondary server when:
The primary CMS server becomes inactive, goes down or CMS is turned off
A link is down on the primary CMS server, but the link to the secondary CMS server is still up. If the link is down on the secondary as well, call the TSC for help to get the link back up (be sure to tell the TSC you have the High Availability feature).
Contact your Avaya Technical Support representative to install and authorize ECHI. In the U. S., call the National Customer Care Center Call Center Helpline at 1-800-242-2121.
