Most SIP desk phones can connect to your PBX. You enter the SIP details from a **SIP device** into the phone's web interface. Field names differ between brands, so use the table below to match them.

For Yealink phones, see [Auto-provisioning](https://kb.voipcloud.online/phones-and-apps/yealink/auto-provisioning/) instead. There are also guides for [Snom](https://kb.voipcloud.online/phones-and-apps/other-phones/snom-phones/) and [Fanvil](https://kb.voipcloud.online/phones-and-apps/other-phones/fanvil-phones/) phones.

## Before you start

1. Add a **SIP device** to the person's [User](https://kb.voipcloud.online/pbx/accept-make-divert/user/) under **Device configuration**, and click **Apply configuration**.
2. Open **Devices** at the top of the **PBX** tab and select the device. Keep its **SIP credentials** open: **Domain**, **Username** and **Password**, plus the **Transport protocol**.
3. Connect the phone to your network and power. Your computer must be on the same network.

The **Domain** shows the server address, a colon and the port. Some phones want them together, others in separate fields.

## 1. Open the phone's web interface

1. Find the phone's IP address in its menu, usually under status or network information.
2. Type the IP address into your web browser.
3. Sign in with the phone's admin username and password. These are in the phone's manual, or from whoever supplied the phone.

## 2. Enter the SIP account

Open the first account or line, and fill in:

| Phone field (common names) | What to enter |
| --- | --- |
| User ID, Username, Register name, Authentication user | The **Username**. |
| Password, Authentication password | The **Password**. |
| Domain, SIP server, Registrar, Server address, Proxy | The server address: the **Domain**, with or without the port as the phone expects. |
| Port, Server port | The number after the colon in the **Domain**. |
| Transport | **TCP**, or TLS with SRTP if the device's **Transport protocol** shows TLS (the port is different then). |
| Expires, Registration expiration, Subscription expires | **120** seconds. |
| Display name | Any name you like. It only shows on the phone. |

Save the settings. Some phones need a reboot.

## Check it works

1. In **PBX** › **Devices**, the SIP device shows **Online**. The phone's status page usually shows the account as registered too.
2. Make a test call and ask someone to call you.

If it stays offline, check every field again and see [Softphone errors](https://kb.voipcloud.online/phones-and-apps/softphones/softphone-errors/). A device that tries to register with a wrong password is blocked, and the block lifts after 5 minutes.

**Important:** Use each SIP device on one phone only. Keep the SIP password private: anyone who has it can make calls charged to your account.
