Instructions on setting up high availability are provided in the Administrator’s Manual.
High availability is necessary precisely in cases in which the SMS Gateway is going about critical tasks. Use a second SMS Gateway to guarantee the smooth sending of text messages. If one SMS Gateway fails, the second SMS Gateway will take over operation.
In order to use the High Availability (HA) functionality of your SMS Gateway, you need:
- A second SMS Gateway with identical licensed modules
- The licensed module High Availability
- A second SIM card
