Answer

If your system is unable to accept inbound SMS when Nexmo tries to forward them, they will be retried every minute for 72 hours.

Delivery receipt callbacks will be retried every minute for 24 hours only.

After this period has expired, the callback will be dropped and you will no longer receive them.
