SIP and SDP are independent of each other. SIP can implement multimedia calls independently to add new applications or media easily.
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?
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?
In the collaboration solution architecture, which of the following network elements are deployed at the media processing layer? (Choose all that apply.)
In the SIP protocol, the Via header field indicates the route of the subsequent response message.
When the MCU has two service network ports, you can use the IP address bound to bond0 or bond1 to access the MCU web interface.
Which of the following registration information types are carried in an RRQ to register with the GK? (Choose all that apply.)
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.
By default, the SMC provides six user roles. Default permissions of each user role can be modified or deleted based on site requirements.

Assume endpoints T1 and T2 are registered with the same SC node zone (signaling routing is disabled on the SC). After T1 calls the number of T2 using H.323, T1 and T2 communicate with each other. In this process, a total of ____________ TCP connection(s) need to be established between T1 and T2. (Enter an Arabic numeral.)
The MCU debugging command “mswt-media config_info” is used to query the configuration information about media exchange.
FILL BLANK
In a SIP-only multipoint conference, when a participant sends the presentation, the system uses the ____________ protocol for presentation. (Enter the abbreviation.)
Currently, the widely used video compression standards include H.263, H.264, H.265, MPEG-1, MPEG-2, and MPEG-4. The H.26X series standards are mainly used for real time video communication, and the MPEG series standards are mainly used for video storage (DVD), video broadcast, and video streaming media.
A company deployed a new Huawei video conferencing system last year (conference rooms are managed by organization). Now, the company plans to add 50 Box 610 devices to meet service requirements. In addition, the company plans to change the conference room management mode to area management in the SMC system to meet their new conference room management requirements. In this case, before provisioning new conference rooms, you can directly click Organization Management to switch to Area Management on the SMC web interface.
