Call Status
Loopback indicates that the system is set to perform a loopback test (On)
or is not set for a loopback test (Off).
AutoConfig indicates that the system is set to automatically configure the
audio algorithm and communications protocol (On) or not (Off).
64 Kbps, G.722 This algorithm uses 64 Kbps of the video call with
an audio frequency range of 7.0 KHz for higher
fidelity than the G.711 and G.728 algorithms.
Although this is a standards-based algorithm, it
may not be available on some non-VTEL systems.
