I was hoping to get some help with configuring a redundant gateway. At present we have a working system that uses Kannel as a gateway to a our SMS provider. Our provider offers redundant sites that load balance so inbound SMS should come through one Kannel gateway to our system. The providers 2 sites are synced to provide a single message ID.
How do I set up a second Kannel gateway as an automatic failover? Is this configured from a higher level in playSMS or is this element handled entirely by Kannel config? In an ideal world, I would have both gateways connected at all times and load balance, then when an SMS fails to send through one gateway I could automatically attempt to send through the other gateway.
Thanks in advance,
