Config lines are an excellent way to customise your phone's settings in bulk, all while keeping things hassle-free.

We've compiled a list of practical config lines that you can set up on your Yealink device.

Please enter each config line on it's own line.

Area Code Auto-Dial Prefix

This is helpful for customers who frequently dial numbers with the same area code - such as 01483 for Guildford.

dialplan.area_code.code = 01483

dialplan.area_code.min_len = 6

dialplan.area_code.max_len = 7

dialplan.area_code.line_id = 1

The sections which are customisable are in Bold.

min_len specifies the minimum number of digits the user must dial for the area code to be automatically added as a prefix.

max_len specifies the maximum number of digits the user must dial before the area code won’t be automatically added as a prefix.

line_id specifies the desired line to apply the area code rule to. 0 will apply to all lines. Multiple line ID’s are separated by commas.

Internal/External Ringing Tone

Use this if a customer would like a different ringtone for internal calls. Please note that other custom ringtones are not currently supported on Yay.

distinctive_ring_tones.alert_info.1.text = Internal

distinctive_ring_tones.alert_info.1.ringer = 3

VoIP Spam - Ghost Calls

This can be used if a customer is experiencing issues with their phone(s) ringing but no one is on the other end of the line when answered.

features.direct_ip_call_enable = 0

sip.trust_ctrl = 1

features.direct_ip_call_enable = 0 disables being able to directly dial a phone by IP address (setting to 1 would enable this feature)

sip.trust_ctrl = 1 forces the device to only accept a SIP message from the SIP server (setting to 0 would disable this).

Pausing Call Recording

This feature can be used if a customer wants a line key to pause recording. However, it’s generally no longer necessary, as these settings can now be managed directly through the user’s provisioning tab in the Yay portal. That being said, it still remains a valuable configuration option.

linekey.6.label = Record Off/On

linekey.6.value = *10 [or whatever the shortcode is]

linekey.6.line = 1

linekey.6.type = 11

Changing Incoming Call Information on Display

This changes the information displayed on the phone for an incoming call.

phone_setting.call_info_display_method = 0

Possible settings:

0 shows the name then Number.

1 shows the number then Name - Some devices can only show a single name and number, so you may need to disable your call route name in order to see your contact’s name appear.

2 shows just the Name.

3 shows just the Number.

4 shows their full contact information (display name sip:xxx@domain.com).

5 shows ‘Null’.

Changing Call History To Display Number/Name (even with Route Nickname turned on

Useful if a customer wants to see Caller ID in Call History but has Route Nickname turned on. This changes the information displayed on the phone’s call history log.

features.call_log_show_num = 2

0 shows the Name

1 shows the Number

2 shows the Name and Number

By default, the Yay.com profile is set to show both the name and number (2).

Change User Display Method When Dialling

Changes the information displayed on the phone’s display when the receiver is picked up to make a call.

features.caller_name_type_on_dialing = 1

1 shows the Label

2 shows the Display Name

3 shows the User Name

Yay displays the Display Name (2) by default, but this can be changed by editing the extension's User Nickname in the Yay portal.

Configuring Call Park BLF’s

Used if a customer wants to set up line keys for Call Parking slots. This is mostly no longer required, as all settings can now be managed through the user's provisioning tab in the Yay portal.

linekey.x.label = Park 1

linekey.x.line = 1

linekey.x.type = 10

linekey.x.value = *11

linekey.x.label = Park 2

linekey.x.line = 1

linekey.x.type = 10

linekey.x.value = *12

linekey.x.label = Park 3

linekey.x.line = 1

linekey.x.type = 10

linekey.x.value = *13

linekey.x.label = Park 4

linekey.x.line = 1

linekey.x.type = 10

linekey.x.value = *14

linekey.x.label = Park 5

linekey.x.line = 1

linekey.x.type = 10

linekey.x.value = *15

Codec Enable/Disable

This is used to enable/disable specific audio codecs on devices and change the priority in which they will be used.

account.1.codec.opus.enable = 1

account.1.codec.opus.priority = 1

account.1.codec.g729.enable = 0

account.1.codec.g729.priority = 8

Change opus/g729 to the appropriate codec type where required.

Priority number 1 is higher, 8 is lower.

Enable codec is 1

Disable codec is 0

Please note that the OPUS codec can cause audio issues on older devices if used as the primary codec.

Admin Password

This is used to set an admin username and password.

security.user_password = admin:admin

Expansion Module Configuration

This can be used to add line keys to an attached expansion module.

expansion_module.1.key.x.type = 16

expansion_module.1.key.x.line = 1

expansion_module.1.key.x.value = 1002

expansion_module.1.key.x.pickup_value = *88

expansion_module.1.key.x.label = Example

Commonly used line key types:

16 for BLF

13 for Speed Dial

11 for DTMF

10 for Call Park

Disable Warning Messages

This turns off warning messages e.g. ‘the default admin password is in use’ warning.

phone_setting.warnings_display.mode = 0

Change Length Of DSS Keys

This changes the length of the line key labels on the phone’s display.

features.config_dsskey_length = 3

1 is Extended

2 is Mid-Range

3 is Default

Enable/Disable LED for missed call notifications

This changes whether a notification will pop up on the phone’s display if a missed call is received.

phone_setting.missed_call_power_led_flash.enable = 0

Adding additional Remote Phone Books via config

This is used to add additional phone books to a device if they already have one assigned from the Yay portal.

remote_phonebook.data.2.name = [Example]

remote_phonebook.data.2.url = [Phonebook URL from Yay account]

Restrict Outbound Calling

This line is used to restrict outbound calls via config lines.

This is largely redundant now as restrictions can be applied in the Yay portal.

dialplan.block_out.number.1 = 00.

This line will block any length number beginning 00 (the dot signifies any number of digits following 00).

dialplan.block_out.number.2 = 0.

This line will block any length number beginning 0 (the dot signifies any number of digits following 0)

If you’re experiencing difficulty provisioning a handset to Yay, you can manually enter the following details as an alternative

static.auto_provision.repeat.enable = 1

static.auto_provision.aes_key_in_file = 1

static.security.trust_certificates = 0

static.auto_provision.server.url = https://provision.voipcp.com/yealink

static.auto_provision.weekly.enable = 1

Hotlining configuration lines that enable the phone to automatically dial a number when picked up.

This feature enables the handset to automatically dial a number or destination as soon as the phone is picked up and taken off the hook. Only one hotline number can be configured per handset.

features.hotline_number = 1001

This line is what number you want to dial, so either a mobile number, landline number or extension (1001)

features.hotline_delay = 1

This line specifies the number of seconds (1-10) the phone should remain off the hook before dialing the hotline number.

If you have any issues with this, or have any questions, please contact Yay.com support on 0330 122 6000, or send in an email to help@yay.com.
