Change for Guide Version 15.1

The following sections are new for this version:

•NET Probe Configuration

•Noise Suppression

•Smart Noise Block

•Acoustic Shield

•Remote Provisioning and Sign in from Teams Admin Center

Major updates have occurred to the following sections:

•Proxy Server Configuration

| Getting Started | 9

•User and Administrator Identification

•User and Administrator Identification Configuration

•Hybrid Mode Configuration

•TLS Configuration

•Using CP960 Cascaded Mode

•Provisioning Devices on the Microsoft Teams Admin Center

Getting Started

This chapter provides basic initialization instructions for Teams devices.

•Initialization Process Overview

•Verifying Startup

•Teams Feature License

Initialization Process Overview

The initialization process of the device is responsible for network connectivity and operation of the device in your local network. Once you connect your device to the network and to an electrical supply, the device begins its initialization process.

•Loading the ROM File

•Configuring the VLAN

•Querying the DHCP (Dynamic Host Configuration Protocol) Server

•Contacting the Provisioning Server

•Updating Firmware

•Downloading the Resource Files

Loading the ROM File

The ROM file resides in the flash memory of the device. The device comes from the factory with a ROM file preloaded. During initialization, the device runs a bootstrap loader that loads and executes the ROM file.

Configuring the VLAN

If you connect the device to a switch, the switch notifies the device of the VLAN information defined on the switch (if using LLDP or CDP). The device can then proceed with the DHCP request for its network settings (if using DHCP).

Querying the DHCP (Dynamic Host Configuration Protocol) Server

The device is capable of querying a DHCP server.

After network connectivity is established, the device can obtain the following network parameters from the DHCP server during initialization:

•IP Address

•Subnet Mask

•Default Gateway

•Primary DNS

•Secondary DNS

| Getting Started | 10

By default, the devices obtain these parameters from a DHCPv4. You can configure network parameters of the device manually if any of them are not supplied by the DHCP server.

Contacting the Provisioning Server

If you configure the device to obtain configurations from the provisioning server, it will be connected to the provisioning server, and then download the boot file and configuration file(s) during startup. The device will be able to resolve and update configurations written in the configuration file(s). If the device does not obtain configurations from the provisioning server, the device will use the configurations stored in the flash memory.

Updating Firmware

If you define the access URL of firmware in the configuration file, the device will download firmware from the provisioning server. If the MD5 value of the downloaded firmware file differs from the one stored in the flash memory, the device will perform a firmware update.

You can manually upgrade the firmware if the device does not download firmware from the provisioning server.

Downloading the Resource Files

In addition to the configuration file(s), the device may require resource files before it provides service. These resource files are optional, but if you deploy some particular features, these files are required.

Verifying Startup

After connected to the power and network, the devices begin the initialization process:

1.The power LED indicators of MP58/MP58-WH/MP56/MP54/T58A/T56A/T55A/VP59 glow red. The mute touch key LED indicators of CP960 glow red.

2.The message “Initializing… Please wait” (or “Initializing…”) appears on the LCD screen when the devices start up.

3.The devices enter the language selection interface.

Teams Feature License

Yealink offers MP58/MP58-WH/MP56/MP54/T58A/T56A/T55A/CP960/VP59 devices configured for use with Microsoft Teams. By default, the device has a built-in Teams feature license, which allows users to use Yealink devices with Teams features directly. If the device has not imported a license yet, the screen will be shown as below:

You need to upload the license to use the device normally.

For the Teams feature license and device version, you need to pay attention to the following points

•Any Open SIP build upgrades to Teams build will be required to apply and import the license.

•Any Teams upgrades to Skype for Business will not need to be required additional license. And vice versa.

•Any Teams will not be allowed to downgrade to the Open SIP from this release. If Teams phones are under temporary license (for demo testing purpose) and want to get back to Open SIP, please contact Yealink support team for technical support for an unlock license.

•Once upgraded to the latest Teams, it will not be allowed to downgrade to the previous Teams version.

For information about purchasing a Teams feature license, contact your reseller or sales representative.

| Device Network | 12

Note: If the device running the Skype for Business firmware has been imported a Skype for Business feature license, you do not need to import the license after you upgrade to the Teams firmware.

•Importing License via the Web User Interface

•Importing License Configuration

Firmware Upgrade

Importing License via the Web User Interface

If the device has not imported a license or the license is expired, you need to import the license manually.

Procedure

1.On your web user interface, go to Security > License.

2.In the Load License File (or Upload License File) block, click the white box to select the license from your local system.

3.Click Upload.

Importing License Configuration

The following table lists the parameter you can use to import license.

Description	It configures the access URL of the Teams feature license.
	Example:
	lync_license_dat.url = http://192.168.1.20/License_$MAC.dat
	The devices will replace the characters “$MAC” with their MAC addresses during
	auto provisioning. For example, the MAC address of one T58A Teams device is
	00156543EC97. When performing auto provisioning, the device will request to
	download the License_00156543ec97.dat file from the provisioning server address
	“http://192.168.1.20”.

Device Network

Yealink Teams devices operate on an Ethernet local area network (LAN). You can configure the local area network to accommodate many network designs, which varies by organizations and Yealink Teams devices.

•IPv4 and IPv6 Network Settings

•DHCP Option for IPv4

•DHCP Option for IPv6

| Device Network | 13

•VLAN

•Wi-Fi

•Internet Port and PC Port

•802.1x Authentication

•Proxy Server

IPv4 and IPv6 Network Settings

Teams devices support IPv4 addressing mode, IPv6 addressing mode, as well as an IPv4&IPv6 dual-stack addressing mode. After connected to the wired network, the devices can obtain the IPv4 or IPv6 network settings from a Dynamic Host Configuration Protocol (DHCP) server if your network supports it. To make it easier to manage IP settings, we recommend using automated DHCP which is possible to eliminate repetitive manual data entry. You can also configure IPv4 or IPv6 network settings manually.

Note: Teams devices comply with the DHCPv4 specifications documented in RFC 2131, and DHCPv6 specifications documented in RFC 3315.

IPv6 Configuration

If you configure the network settings on the device for an IPv6 network, you can set up an IP address for the device by using SLAAC (ICMPv6), DHCPv6, or by manually entering an IP address. Ensure that your network environment supports IPv6. Contact your ISP for more information.

When you enable both SLAAC and DHCPv6 on the device, the server can specify the device to obtain the IPv6 address and other network settings either from SLAAC or from DHCPv6, if the SLAAC server is not working, the device will try to obtain the IPv6 address and other network settings via DHCPv6.

The following table lists the parameters you can use to configure IPv6.

Parameter	static.network.ipv6_internet_port.type[1]	<MAC>.cfg
Description	It configures the Internet port type for IPv6.

DHCP Option 160 and Option 161

Yealink Teams devices support obtaining the provisioning server address by detecting DHCP custom option during startup.

If DHCP Option 66 is not available, you can use custom option (160 or 161) with the URL or IP address of the provisioning server. The device will automatically detect the option 160 or 161 for obtaining the provisioning server address.

To use DHCP option 160 or option 161, make sure the DHCP Active feature is enabled and the custom option is configured.

•DHCP Option 160 and Option 161 Configuration

DHCP Option 160 and Option 161 Configuration

The following table lists the parameters you can use to configure DHCP option 160 or 161.

Parameter	static.auto_provision.dhcp_option.enable[1]	<y0000000000xx>.cfg
Description	It triggers the DHCP Option feature to on or off.
Permitted	0-Off
Values
	1-On
Default	1
Web UI	Settings > Auto Provision > DHCP Active
Parameter	static.auto_provision.dhcp_option.list_user_options[1]	<y0000000000xx>.cfg
Description	It configures the custom DHCP option for requesting provisioning server address.
	Multiple DHCP options are separated by commas.
	Note: It works only if “static.auto_provision.dhcp_option.enable” is set to 1 (On).
Permitted	Integer from 128 to 254
Values
Default	160,161
Web UI	Settings > Auto Provision > Custom Option

[1]If you change this parameter, the device will reboot to make the change take effect.

DHCP Option 66, Option 43 and Custom Option

During the startup, the device will automatically detect the custom option, option 66, or option 43 for obtaining the provisioning server address. The priority of obtaining the provisioning server address is as follows: custom option > option 66 (identify the TFTP server) > option 43.

The Teams device can obtain the Auto Configuration Server (ACS) address by detecting option 43 during startup.

To obtain the server address via DHCP option, make sure you have configured the DHCP option on the device. The option must be in accordance with the one defined in the DHCP server.

Note: If you fail to configure the DHCP options for discovering the provisioning server on the DHCP server, an alternate method of automatically discovering the provisioning server address is required. One possibility is that connecting to the secondary DHCP server that responds to DHCP INFORM queries with a requested provisioning server address. For more information, refer to RFC 3925.

| Device Network | 21

If a single alternate DHCP server responds, this is functionally equivalent to the scenario where the primary DHCP server responds with a valid provisioning server address. If no DHCP server responds, the INFORM query process will retry and until the time is out.

DHCP Option 42 and Option 2

Yealink Teams devices can use the NTP server address offered by DHCP.

DHCP option 42 is used to specify a list of NTP servers available to the client by IP address. NTP servers should be listed in order of preference.

DHCP option 2 is used to specify the offset of the client’s subnet in seconds from Coordinated Universal Time (UTC).

VLAN

The purpose of VLAN configurations on the device is to insert a tag with VLAN information to the packets generated by the device. When VLAN is properly configured for the ports (Internet port and PC port) on the device, the device will tag all packets from these ports with the VLAN ID. The switch receives and forwards the tagged packets to the corresponding VLAN according to the VLAN ID in the tag, as described in IEEE Std 802.3.

VLAN on devices allows simultaneous access to a regular PC. This feature allows a PC to be daisy chained to a device and the connection for both PC and phone to be trunked through the same physical Ethernet cable.

In addition to manual configuration, the device also supports the automatic discovery of VLAN via LLDP, CDP, or DHCP. The assignment takes effect in this order: assignment via LLDP/CDP, manual configuration, then assignment via DHCP.

LLDP Configuration

LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which allows devices to receive and/or transmit device-related information from/to directly connected devices on the network that are also using the protocol, and store the information about other devices.

When the LLDP feature is enabled on the devices, the devices periodically advertise their information to the directly connected LLDP-enabled switch. The devices can also receive LLDP packets from the connected switch. When the application type is “voice”, the devices decide whether to update the VLAN

configurations obtained from the LLDP packets. When the VLAN configurations on the devices are different from the ones sent by the switch, the devices perform an update and reboot. This allows the devices to plug into any switch, obtain their VLAN IDs, and then start communications with the call control.

The following table lists the parameters you can use to configure LLDP.

Parameter	static.network.lldp.enable[1]	<y0000000000xx>.cfg
Description	It enables or disables the LLDP feature on the device.
Permitted Values	0-Disabled
	1-Enabled, the device will attempt to determine its VLAN ID through LLDP.

CDP Configuration

CDP (Cisco Discovery Protocol) allows devices to receive and/or transmit device-related information from/ to directly connected devices on the network that are also using the protocol, and store the information about other devices.

If the CDP feature is enabled on the devices, the devices will periodically advertise their information to the directly connected CDP-enabled switch. The devices can also receive CDP packets from the connected switch. If the VLAN configurations on the devices are different from the ones sent by the switch, the devices

| Device Network | 24

will perform an update and reboot. This allows you to connect the devices into any switch, obtain their VLAN IDs, and then start communications with the call control.
