Carrier Retry Rates

Omni SMPP:

Delivery Retry:

On delivery failure of a message, the gateway will automatically re-queue the message and retry it 60 seconds later. The gateway will continue retrying up to 50 times at which point the message is flagged as ‘frozen’. This means that if an external party (e.g. A customer or carrier server) is temporarily overloaded, or the network connection drops out, the retry process will ensure ultimate delivery pending the resource becoming available within the 50-minute window.

Failed Message Overflow:

Whenever a customer using our standard Web Services interface is unreachable due to network issues or a server outage we re-queue their message (see Delivery Retry). However, to minimise the impact of a slow-responding server, all of that customer’s messages are moved off the main queue to a second queue. This ensures continued rapid delivery rates to other customers whose service will not be impacted, whilst the unreachable customer does not lose any messages.

  • 4th level retry - 10 minutes, 1 time

  • 5th level retry - 15 minutes, 2 times

  • 6th level retry - 45 minutes, 1 time

  • 7th level retry - 3 hours, 56 times

  • After each level is exhausted its number of retries, it will climb to the next level.

  • If the retry period passes and no DLR was returned you will receive the expired status (if this is visible to Optus)

Validity Period:

  • 7 days (unless changed during submission)

Note: For any message sent via Optus to international operators the retry and final delivery status is dependent on the recipient carrier, some can be transactional and therefore the Optus retry pattern would still apply, others would use their own retry patterns.
