Null Values

You can override any provisioned value by entering %NULL%

I.e. firmware.url.server_type="%NULL%"

Directed Call Pickup

• features.pickup.direct_pickup_enable=“1”
• features.pickup.direct_pickup_code="*35"

Distinctive Ring

The Distinctive Ring feature works by adding a department name to the extension

• account.1.alert_info_url_enable=“1”
• distinctive_ring_tones.alert_info.1.text=“Restaurant”
• distinctive_ring_tones.alert_info.1.ringer=“2”

The example above will cause any Yealink phone to use Ringer 2 whenever a call is received from a member of the ‘Restaurant’ department.

NOTE: If your department has space(s) in it, do not include the space(s) when adding it to the override.

Ringer Volume

It is sometimes necessary to lock the ringer volume at the administrative level. This can be done by setting the below value to 0 through 15, with 15 being the loudest. If any value is set, the rocker switch will not work. You can set this value to %NULL% in order to restore volume rocker functionality.

force.voice.ring_vol=“10”

Speed Dial to Voicemail Without Entering PIN

features.enhanced_dss_keys.enable=“1” linekey.X.type=“73” linekey.X.line=“1” linekey.X.label=“Speeddial VM” linekey.X.value=”9900,Extension,,,PIN#”

(Replace ‘X’ with the number of the BLF key you are setting) The overrides above will let you have a BLF key as a Speed dial to dial into a voicemail box without entering a PIN

Example: Extension 101 has 1234 PIN, the override will look like this: linekey.10.value=”9900,101,,,1234#

Please note, that some Yealink firmware versions have stopped allowing commas as spacers.
Please refer to the override below:

features.enhanced_dss_keys.enable=“1”
linekey.3.type=“73”
linekey.3.line=“1”
linekey.3.label=“Speeddial VM”
linekey.3.value=“9900$Cwc$$Cp5$1019$Tdtmf$$Cp5$7538$Tdtmf$”

In this example the key will be placed on Line 3, 9900 is used to dial Voicemail with prompt for extension and voicemail pin. 1025 is the extension we are trying to reach. 7539 is the voicemail pin.

Substitute the Extension and Voicemail Pin, then save and resync.

Setup Wi-Fi via Override

Via override, you can “pre-install” Wi-Fi SSIDs on Yealink phones once provided. Please replace the X with a number, starting at 1, you can setup up to 99 SSIDs.

static.wifi.function.enable=“1”

Enables the Wi-Fi feature.
static.wifi.enable=“1”

This enables Wi-Fi mode.
static.wifi.X.ssid=“Wi-Fi SSID”
static.wifi.X.security_mode=“WPA/WPA2 PSK”

Permitted values: NONE, WEP, WPA/WPA2 PSK, WPA3-Personal, 802.1x EAP
static.wifi.X.password=“Wi-Fi Password”

Change Transfer Mode

By default, the Transfer mode is Attended Transfer, you can change this mode on devices via this override:

transfer.dsskey_deal_type=“X”

Replace X with one of the following:

• 0 - New Call
• 1 - Attended Transfer (this is the default)
• 2 - Blind Transfer
• 4 - Optional Selection

features.save_init_num_to_history.enable = 0

Enabling Auto Answer via Override

Please use the following override either via domain or via phone hardware page. You will need to just X accordingly to the account this will affect.

account.x.auto_answer=“1”
0 = Disabled
1 = Enabled, the phone can automatically answer an incoming call.

NOTE: The phone cannot automatically answer the incoming call during a call or while dialing even if auto answer is enabled.

Default Directory Key to Remote Phonebook

Issue: Yealink Phones – Directory Key Defaults to Local Directory Only

By default, Yealink phones have the “Directory” programmable key set to open the Local Directory, which is often blank. This behavior prevents users from easily accessing the Remote Phonebook, even though it’s uploaded and available.

Solution: Override Directory Key to Open Remote Phonebook

To make the Directory button open the Remote Phonebook (e.g., “Company Directory”) automatically, apply the following configuration overrides:

programablekey.2.type="22"
programablekey.2.line="Company Directory"
programablekey.2.label="Directory"

These overrides can be pushed via SNAPbuilder. No changes are needed unless you want to customize the label.

Name Scrolling Display

For the case that a long station name in a small phone screen, you can enable or disable the IP phone to scroll the string display on the top-left corner of the LCD screen.

0 = Disabled

1 = Enabled

• features.station_name.scrolling_display=“1”
