owner sets the request as Unauthorized, you need to wait for the device owner's
consent after each request you initiate.

Procedure
1. On the device diagnostics page, click One-Click Export.
2. Set parameters and click Export. For more information about packet strings, see
  commonly used packet strings.

  💡   NOTE
      You can enter the string only when you select Customize from the drop-down menu of the
      Capture Type. Besides, if you do not enter the string, the system will capture all the data
      packets.

Diagnose Network
Procedure
1. On the device diagnostics page, click Network Detection.
2. Select any detection method and set the parameters:
    Ping (ICMP Echo): by sending a data packet to the remote party and requesting the
    party to return a data packet of the same size, this method can identify whether those
    two devices are connected. The diagnostic results include a brief summary of the
    received packets, as well as the minimum, maximum, and average round trip times of
    the packets.
    Trace Route: this method records the route from the local device to the remote device. If
    this test succeeds, you can view the network node and the time taken from one node to
    the other to check whether or not there is network congestion.




3. Click Detect.



Remote Control
Introduction
You can remotely operate the touch screen of the devices and troubleshoot
problems through remote control. Due to data security, YMCS only accesses data

                                                                                       13 / 197

on the touch screen and does not store it during remote control.

Prerequisites
  You have assigned the pro license to the meeting room.
  Do one of the following:
    If your enterprise is located in EU region, please refer to the network requirements of
    remote control under EU region and open the relevant domain name and port;
    If your enterprise is located in US region, please refer to the network requirements of
    remote control under US region and open the relevant domain name and port.
    If your enterprise is located in AU region, please refer to the network requirements of
    remote control under AU region and open the relevant domain name and port.
    If your enterprise is located in UAE region, please refer to the network requirements of
    remote control under UAE region and open the relevant domain name and port.
  Supported devices: MVC Series/MeetingBoard/MeetingBar/MeetingEye/DeskVision A24.
    For MeetingBoard/MeetingBar/MeetingEye, you can simultaneously remote control the
    host device and its touch screen (requires independent connecting to YMCS).
    For MVC Series/DeskVision A24, only a single device can be remotely controlled at a time.
  The device status needs to be online.
  The remote control feature is enabled.
  The device owner allows you to remote control. For more information, see device
  authorization status-general issues.

Procedure
1. On the device diagnostics page, click Remote Control.




                                                                                       14 / 197
  Yealink Management Cloud Service(YMCS) U...




2. If the enterprise has assigned the remote control license and the device has not yet been
  assigned to a conference room, you need to assign it first before further using the remote
  control function.
    Create a New Room with Pro License: Create a new room and edit related information
    such as name, location, capacity, etc. The pro license will be automatically assigned to
    the created room.
    Select a Existing Room: Select an existing room. If the room does not have a pro license,
    a new license will be automatically assigned to it.




                                                                                       15 / 197
