Payload Redundancy
You can accredit burden back-up so the modem pass-through over VoIP switchover
causes the aperture to accelerate bombastic packets. Back-up can be enabled in one or
both of the gateways. When alone a distinct aperture is configured for redundancy, the
other aperture receives the packets correctly, but does not aftermath bombastic packets.
When back-up is enabled, 10 ms sample-sized packets are sent. When back-up is
disabled, 20 ms sample-sized packets are sent.
