Adding Local Contacts on page 59.
6. Press (Save soft key) to save the contact.
Call history management feature is configurable via web user interface at the path
Directory->History.
Call Protocol
The VC120 video conferencing system supports SIP and H.323 call protocols. H.323 is commonly
used to communicate to other video conferencing systems. SIP is commonly used to
communicate with other VoIP devices. You can configure which protocol is to be used when the
system is making calls. When the Auto call protocol is used, the system preferentially uses the
H.323 protocol to place calls. If there is no available H.323 account on the system, the system
will switch to the SIP protocol. You can also specify the desired protocol for the system to place
calls via the remote control or web user interface.
Note
To configure the call protocol via the remote control:
1. Press (Menu soft key) to enter main menu.
2. Press or to select the Call Features menu.

Customizing the VC120 Video Conferencing System
The actual bandwidth depends on the performance of the remote system, and is affected by the
quality of the communication channel.
3. Press or to scroll to Call Protocol, and then press .
4. Select desired type or Auto from the pull-down list of Call Protocol.
5. Press (Save soft key) to accept the change.
Call protocol is configurable via web user interface at the path Setting->Call Features->Call
Protocol.
Bandwidth Settings
By default, the system automatically detects the available bandwidth and uses this connection
speed. The VC120 supports connecting to other devices with different bandwidth. If a device
with lower bandwidth joins a call, the video quality will stay the same or will not reduce a lot.
You can specify the uplink and downlink bandwidths for the system to achieve the best result.
The uplink bandwidth refers to the max bandwidth of outgoing calls. The downlink bandwidth
refers to the max bandwidth of incoming calls.
Available bandwidths for the system are: Auto, 256kb/s, 384kb/s, 512 kb/s, 640 kb/s, 768 kb/s,
1024kb/s, 1280kb/s, 1500kb/s, 2000kb/s, 3000kb/s, 4000kb/s, 5000kb/s, 6000kb/s.
You can configure the uplink and downlink bandwidth of the system via the remote control or
web user interface.
Note
To configure the uplink and downlink bandwidth via the remote control:
1. Press (Menu soft key) to enter main menu.
2. Press or to select the Call Features menu.
75
User Guide for the VC120 Video Conferencing System
The priority of bandwidth is as follows:
System bandwidth>Contact bandwidth (refer to Adding Local Contacts).
For example: the system bandwidth is 512kbps, if contact bandwidth is set to a value greater than
512bps, then the actual contact bandwidth will be 512bps. If contact bandwidth is set to a value
less than 512bps, then the actual contact bandwidth will be the value set by user.
3. Press or to scroll to Bandwidth Settings, and then press .
4. Select desired bandwidth from the pull-down list of Uplink Bandwidth.
If Auto is selected, the system will select the appropriate bandwidth automatically.
5. Select desired bandwidth from the pull-down list of Downlink Bandwidth.
If Auto is selected, the system will select the appropriate bandwidth automatically.
Note
6. Press (Save soft key) to accept the change.
Bandwidth is configurable via web user interface at the path Setting->Call Features-> Uplink
Bandwidth/Downlink Bandwidth.

Customizing the VC120 Video Conferencing System
By default, the VC120 automatically selects the audio input devices with the highest priority. If
you select “Line In + device” option, the VC120 will use microphone connected to the Line In
port and the corresponding device to pick up audio at the same time.
You can also specify the desired audio input device via the remote control or the web user
interface.
To configure the audio input device via the remote control:
1. Press (Menu soft key) to enter main menu.

3. Press or to scroll to Audio Setting, and then press .
4. Select desired audio input device from the pull-down list of Audio Input.
- If VCS Phone is selected as the audio output device manually or automatically, the
audio input device must be VCS Phone or Line Input +VCS Phone.
- If Line Input is selected as the audio input device, the near-end audio output device
will not play sound from the Line Input device.
- If “Line In + device” is selected as the audio input device, the near-end audio output
device will play sound from the Line Input device.
During a video training for main office and branch office, both offices need to hear
the video sound, you can select this option.

Using the VC120 Video Conferencing System
The VC120 video conferencing system can be used to place calls, answer calls, or conduct a
conference cal. 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:
1. Click on Setting->Call Features.
2. 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.
83
User Guide for the VC120 Video Conferencing System
- If you select Enabled, the system will attempt to call other system using different call
types according the priority.
3. Click Confirm to accept the change.
The following example shows the way calls are placed when account polling is enabled or
disabled.
Scenario:
1. System A is registered with a Yealink Cloud account and a SIP account.
84
Using the VC120 Video Conferencing System
2. On system A, select Auto from the pull-down list of Call Type before calling.
3. 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.
85
User Guide for the VC120 Video Conferencing System
To import the 8-way MCU via web user interface:
1. Click on Security ->License.
2. Click Browse to locate the MCU license (the file format must be *.dat) from your local
system.
3. Click Upload to complete importing the MCU license.
To view 8-way MCU status via the remote control:
1. Press (Menu soft key) to enter main menu.
2. Press or to select the Status menu.
3. Press or to scroll to License, and then press .
- 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.
