When a Yealink phone is [auto-provisioned](https://kb.voipcloud.online/au/phones-and-apps/yealink/auto-provisioning/), you can push extra settings to it from the PBX. This saves configuring each phone by hand, and the settings come back after a factory reset.

## Where to enter settings

1. Go to **PBX** › **Devices** and select the phone's SIP device.
2. Expand **Yealink settings** and type your lines in **Advanced CFG configuration**.
3. Click **Save**, then **Apply configuration**.
4. Restart the phone so it downloads the new settings.

Write one setting per line, as `parameter = value`. Replace everything in angle brackets, such as `<label>`, with your own value and remove the brackets.

**Tip:** Most settings below are per account or per key. The number in the parameter (for example `account.2` or `linekey.3`) says which one.

## Add a second SIP account to one phone

Use this when one person handles two lines, for example two brands with different numbers. Each line shows separately on the phone, so the person can choose which caller ID to call out with.

1. Create a second SIP device in **PBX** › **Devices** and add it to a user. It needs its own device licence.
2. Open the second device and expand **Yealink settings**.
3. Choose the same **Yealink device model** and enter the same **Yealink MAC address** as the first device.
4. Click **Save**, then **Apply configuration**, and restart the phone.

The PBX puts every SIP device with the same MAC address on the phone as a separate account, with the right server, port and transport. For a third account, repeat with another SIP device.

## BLF and speed dial keys

A BLF key shows whether a colleague is free (green) or on a call (red), and calls them with one press. A speed dial key calls a saved number.

```ini
linekey.1.type = <16 for BLF, 13 for speed dial>
linekey.1.value = <internal number, or the phone number for speed dial>
linekey.1.label = <text shown next to the key>
linekey.1.line = 1
linekey.1.extension =
```

Change `linekey.1` to the key you want to set. For a BLF key, use the user's internal number from their [User](https://kb.voipcloud.online/au/pbx/accept-make-divert/user/) settings. To set keys by hand instead, see [BLF and speed dial keys](https://kb.voipcloud.online/au/phones-and-apps/yealink/dss-keys-blf-speed-dial/).

## Make transfers blind instead of attended

By default, an auto-provisioned phone uses an attended transfer: you talk to the colleague before handing the call over. Some teams prefer a blind transfer, which sends the call straight through.

```ini
transfer.tran_others_after_conf_enable = 0
transfer.dsskey_deal_type = 2
transfer.on_hook_trans_enable = 0
transfer.blind_tran_on_hook_enable = 1
transfer.semi_attend_tran_enable = 0
```

See [Transfer calls on a Yealink phone](https://kb.voipcloud.online/au/phones-and-apps/yealink/transfer-calls-on-yealink/) for how each transfer type works.

## Load a shared phonebook

Show a [phonebook](https://kb.voipcloud.online/au/pbx/settings/phonebooks/) from the PBX in the phone's **Directory**.

The first phonebook selected in the person's [User](https://kb.voipcloud.online/au/pbx/accept-make-divert/user/) settings is added to the phone automatically. Use these lines only for extra phonebooks.

1. In **PBX** › **Phonebooks**, open the phonebook, click **URLs**, then **XML Yealink URL**. Copy the web address that opens.
2. Add these lines:

```ini
remote_phonebook.data.2.url = <XML Yealink URL>
remote_phonebook.data.2.name = <name shown on the phone>
features.remote_phonebook.enable = 1
features.remote_phonebook.flash_time = 3600
directory_setting.remote_phone_book.enable = 1
```

Start at `data.2`: the PBX uses `data.1` for the user's phonebook and overwrites it. For another phonebook, add a `url` and `name` pair with `data.3`, and so on. Desk phones work best with no more than 4 phonebooks. `flash_time` is how often the phone refreshes the phonebook, in seconds (3600 is hourly).

## A different ringtone for some calls

Use a distinctive ringtone so people know which number or menu option a call came from, or whether it's internal.

1. Add a [Caller ID prefix](https://kb.voipcloud.online/au/pbx/identifiers/caller-id-prefix/) object to the call path, and enter some text in **Alert info**, for example `Line 1`.
2. Find the ringtone name in the phone's web interface. Built-in tones have names such as `Ring1.wav`; the list differs by model.
3. Add these lines to the phone's SIP device:

```ini
distinctive_ring_tones.alert_info.1.text = <the Alert info text>
distinctive_ring_tones.alert_info.1.ringer = <ringtone, for example Ring8.wav>
```

If people call each other with BLF keys, point those keys at an [Internal number](https://kb.voipcloud.online/au/pbx/receive-calls/internal-number/) that passes through the Caller ID prefix, so internal calls get the tone too.

## Show the caller's number on transferred and parked calls

By default, a transferred or parked call shows the colleague who transferred it. To show the original caller instead, add the line below for each account (`account.1`, `account.2` and so on):

```ini
account.1.cid_source = 3
```

The value 3 is **RPID-PAI-FROM**. See [Caller ID on transferred calls](https://kb.voipcloud.online/au/phones-and-apps/yealink/caller-id-on-transferred-calls/) for the limits and the other step that's needed.

## Change NAT traversal

Auto-provisioning turns NAT traversal (STUN) on for each account. If phones drop their registration behind your router, turning it off for the account can help:

```ini
account.1.nat.nat_traversal = 0
```

`0` is off and `1` is on.

## Hide "Q.850" error text on failed calls

```ini
sip.call_fail_use_reason.enable = 0
```

See [Yealink common issues](https://kb.voipcloud.online/au/phones-and-apps/yealink/yealink-common-issues/#q850-cause-on-the-screen).

## Custom wallpaper or logo

See [Logo and wallpaper](https://kb.voipcloud.online/au/phones-and-apps/yealink/logo-and-wallpaper/) for the file formats and the lines to add.

## Find other settings

Yealink publishes an administrator guide for each model with every parameter you can set. On Yealink's support site, choose your model and open the administrator guide that matches your firmware. Use the parameters from that guide in **Advanced CFG configuration**.
