Using the VC120 Video Conferencing System
The VC120 video conferencing system can be used to place calls, answer calls, or conduct a conference call. You can switch layout, record videos or capture screenshots during a call.
This chapter provides basic operating instructions for the VC120 video conferencing system. Topics include:
- Account Polling
- 8-way MCU
- Placing Calls
- Answering or Rejecting Calls
- Ending Calls
- Call Management
If you require additional information or assistance with your new phone, contact your system administrator.
Account Polling
When you dial account numbers of other system, account polling feature enables your system to use different call types according to this priority: Cloud platform>H.323 account>SIP account. If you cannot call other systems using all your registered accounts, then this call fails.
Account polling is disabled by default. When you register multiple accounts (2 or more) for your system, you can enable account polling feature. You can configure account polling feature via web user interface only.
To configure account polling via web user interface:
- Click on Setting->Call Features.
- Select the desired value from the pull-down list of Account Polling.
- If you select Disabled, the system can only call other systems using the call type with the highest priority.
- If you select Enabled, the system will attempt to call other system using different call types according the priority.

- Click Confirm to accept the change.
The following example shows the way calls are placed when account polling is enabled or disabled.
Scenario:
-
System A is registered with a Yealink Cloud account and a SIP account.
-
On system A, select Auto from the pull-down list of Call Type before calling.

- On system A, dial the account numbers of system B.
Result:
- If account polling is disabled, system A can only use its Cloud account (highest priority) to call system B.
- If account polling is enabled, system A will use its Cloud account (highest priority) to call system B first. If this call fails, system A continues to use its SIP account (next priority) to call system B.
8-way MCU
To initiate a multipoint conference, you must use an MCU.
Without 8-way MCU, the VC120 video conferencing system supports one video calls and an additional voice call (an original caller and two other sites). You can import an 8-way MCU to extend the VC120 to support 8-way video calls and an additional voice call (an original caller and eight other sites). 8-way MCU is configurable via web user interface only.
VC120 video conferencing system supports a permanent version of the 8-way MCU and a trial version of the 8-way MCU. They have the same feature.
- Permanent version of the 8-way MCU: each VC120 has a unique MCU license. The MCU license cannot be used for other systems. You need to contact Yealink resellers to purchase it, please provide the MAC address of your VC120 when purchasing.
- Trial version of the 8-way MCU: VC120 models can share this MCU license. You can download a 30-day trial from Yealink website.
To import the 8-way MCU via web user interface:
- Click on Security ->License.
- Click Browse to locate the MCU license (the file format must be *.dat) from your local system.

- Click Upload to complete importing the MCU license.
To view 8-way MCU status via the remote control:
- Press (Menu soft key) to enter main menu.
- Press ◀ or ▶ to select the Status menu.
- Press ▲ or ▼ to scroll to License, and then press OK.
- If the 8 way MCU displays Unsupported, it means you have not imported an 8-way MCU. So the system supports one video call and one voice call.

- If the 8 way MCU displays X\~Y Available, it means you have imported a trail version of 8-way MCU. So the system supports up to 8-way video calls and an additional voice call (an original caller and eight other sites) in X\~Y period. When the trial license expires, your system supports one video call and one voice call.

- If the 8 way MCU displays Eternal, it means you have imported a permanent version of the 8-way MCU. So the system supports up to 8-way video calls and an additional voice call (an original caller and eight other sites) permanently.

8-way MCU status can be viewed via web user interface at the path Status->License.
Note
Upgrading the system or performing a factory reset will not affect the imported 8-way MCU.
If the system has been imported a trial version of the 8-way MCU and the license has not expired, and you import a permanent version to the system, the permanent version will overwrite the trial version.
If the system has been imported a permanent version of the 8-way MCU, and you import a trial version to the system, the permanent version will not be overwritten.
Placing Calls

-
Check whether the far site has already up to maximum call-in limitation.
-
If the local site is forced to use encryption, ensure that the far site enables encryption too.
- Ensure that the far site supports the same call protocol as the local site.
Why does the system fail to call the far site via IP address?
- Ensure that the network is connected correctly.
- Ping the IP address of the far site. Contact your system administrator if it fails.
Camera Issues
How to adjust room lighting?
You can alter the environmental lighting and background colors of your environment to obtain the best video quality. If light levels are too low you may consider adding artificial lighting. Reflected light from pale walls often produces excellent results.
Avoid the following situations:
- Direct sunlight on the display device, the background, or the camera lens which creates harsh contrasts.
- Colored lighting.
Why can't I adjust the camera angle and focus?
- You can adjust the camera when the system is idle or during a call. The camera cannot be adjusted when the system is in the menu screen.
- Ensure that the batteries in the remote control are in good working condition, and installed correctly.
- Aim the remote control at the sensor when you perform a task.
- Ensure that no objects are obstructing the sensor on the front of the camera.
- Ensure that the LED on the front of the camera flashes green when you use the remote control to perform a task.
- Ensure that what you are controlling is the local camera.

Why can't I view the menu on the display device?
- Check whether the Display1 port of VC120 Codec is connected to the HDMI port on the display device.
Why can't I hear the other site clearly during a call?
- Ensure that the speaker volume of the far site is not set too low.
- Muffled audio reception from the far side may be caused by highly reverberant rooms. Speak in close proximity to the phone.
- Adjust the priority order for your audio codec if you have chosen a low-bandwidth audio codec to be first.
- For best results, ensure that the caller is using a Yealink video conferencing system. Audio quality from your video conferencing system will vary when calling a non-Yealink system.
- Dust and debris may cause audio quality. Do not use any kind of liquid or aerosol cleaner on the phone. A soft, slightly damp cloth should be sufficient to clean the top surface of the phone if necessary.
Why is the voice quality poor?
Users may receive poor voice quality during a call, such as intermittent voice, low volume, echo or other noise. It is difficulty to diagnosis the root causes of the voice anomalies. The possible reasons are:
- Users sit too far from or near to the microphone.
- The audio pickup device is moved frequently.
- Intermittent voice is probably caused by voice packet loss or jitter. Voice packet loss may occur due to network congestion. Jitter may occur due to information reorganization of the transmission or receiving equipment, such as, delay processing, retransmission mechanism or buffer overflow.
- Noise devices, such as computers or fans, may make it difficult to hear each other's voices clearly.
- Wires may also cause this problem. Replace the old with the new cables, and then reconnect to check whether the new cables provide better connectivity.
