feedback flag in the SDP answer sent to the SIP entity only if it was
present in the SDP offer received from the other SIP entity.

[2] As Is = The device does not involve itself in the feedback, but
simply forwards any feedback indication as is.
Note:

As RTCP-based feedback has been defined by the WebRTC
standard as mandatory, the support is important for deployments
implementing WebRTC. For more information on WebRTC, see
WebRTC on page 514.

RTCP-based feedback is required for the VoIPerfect feature (see
VoIPerfect on page 528).
Enables the device to detect speech and network quality (packet loss
and bandwidth reduction) and triggers the device to overcome adverse
conditions to ensure high call quality.

[0] Disable (default)

[1] Enable
Note: The parameter is applicable only to the VoIPerfect feature (see
VoIPerfect on page 528).
Defines the VoIPerfect mode of operation, which is based on the Opus
