# Provisioning SIP Phone Equipment

**You are here:** [PBX User](/en-us/article/becoming-an-nettalk-pbx-user-1x2k2x9/) | [Feature Configuration](/en-us/article/pbx-feature-configuration-v07gfo/) | **Extension: Equipment Provisioning**

# Provisioning SIP Phone Equipment

**SIP Phone Provisioning **will configure your phone with the VoIP SIP username and password credentials of an extension and allow you to make and receive calls using the extension on the phone.

## Where do I find my extension's configuration credentials?

1. Sign in to the PBX Configuration Portal at https://account.ntconnect.com/site/login

2. Select the **PBX Account** you want to configure.

3. Click on **Extensions**.

4. Find the extension you want to provision and click the blue **"Credentials"** button that has the key icon to see the credentials page.

You will find the credentials of your extension on this page. 

* Domain
* Proxy
* SIP Username
* SIP password

You have two ways you can provision your phone: 

* Automatic Configuration (_Some GrandStream phones only!_)
* Manual Configuration

## Automatic Configuration

|| *Automatic configuration and provisioning only works with the Grandstream GRP2612W Phone, sold by NT Connect.
1. Click on the **"Auto-Configuration"** button

2. Click on the **"Update MAC Address"** button

3. **Enter the MAC address** of your GrandStream GRP2612W phone. You can find the MAC address underneath your phone equipment.

4. Click the **"Save"** button to update configuration of the extension.

5. **Power cycle** your GrandStream GRP2612W phone. (Power cycling your phone means you will unplug your phone from the wall outlet, wait a few seconds, and then plug it back in.)

Your GrandStream GRP2612W phone will automatically provision with the extension credentials as it powers back on.

## Manual Configuration

1. Refer to your SIP phone's **instruction manual **to learn how to enter the VoIP SIP credentials.

2. Enter the **Domain, Proxy, SIP Username, and SIP password**, that are displayed on the credentials page, into your SIP phone and save your settings.

3. You may need to **power cycle** your phone. (Power cycling your phone means you will unplug your phone from the wall outlet, wait a few seconds, and then plug it back in.)

Your SIP phone will automatically provision with the extension credentials as it powers back on.
