The MCU debugging command “mswt-media config_info” is used to query the configuration information about media exchange.
The VDC can be used with the Huawei video conferencing platform to provide rich conference control functions. Conference control settings can be customized, and conference control shortcut keys and descriptions can be set.
In the encrypted conference scenario, the SIP transmission type must be set to TLS on both the MCU and endpoint.
Assume that a dual-channel audio file uses the PCM encoding, the sampling frequency is 8 kHz, and each quantized sample value corresponds to an 8-bit binary code. What is the encoding rate (kbit/s) of the audio file?
After an AVC conference is held, a user logs in to the MCU and runs the debug command. The following information is displayed:
Which of the following is the IP address of site T3?
FILL BLANK
In an SVC intelligent forwarding conference, if an SVC participant requires to view 1080p video, the bandwidth of the SVC participant must be at least ____________ Mbit/s. (Enter an Arabic numeral.)
In the non-DMZ public-private network traversal scenario (small- and medium-sized network where the SMC and SC are co-deployed), you need to configure the LAN2 port of the SC as the default routing port.
SIP and SDP are independent of each other. SIP can implement multimedia calls independently to add new applications or media easily.
In an SVC hybrid conference (scheduled on the SFU and IAU), when an AVC participant views continuous presence of an SVC participant, dynamic codec resources on the IAU are consumed. When an AVC participant views continuous presence of other AVC participants, no dynamic codec resources are consumed.

When Dual-screen mode is set to Manual for the Box 310/610, which of the following options can be selected for Output port policy? (Choose all that apply.)
SIP is an application-layer protocol independent of the transport-layer protocols. It can be carried over different transport protocols, such as UDP, TCP, TLS, and SCTP. Currently, SCTP is the most commonly used transport-layer protocol.
