          Sistem notifikasi Omni-Messenger memiliki protokol eskalasi otomatis. Jika pengiriman melalui metode utama (misal: Telegram) gagal diverifikasi (tidak ada *delivery receipt*), sistem akan secara otomatis melimpahkan pesan ke rute komunikasi *fallback* aktif Anda berikutnya untuk menjamin informasi tagihan Anda tidak terlewatkan.
