# Provision Cisco 3PCC Phones for VoIP Service

## Objective

Provision [supported](https://www.8x8.com/products/devices/compatibility) or non-supported Cisco 3PCC phones for 8x8 VoIP service.

## Applies To

- 8x8 supported / BYOP “Bring Your Own Phone” (Cisco Multiplatform Phones “3PCC”)
- 8x8 non compatible (Cisco Enterprise Phones “CP”)

8x8 supports the following Cisco 3PCC phones listed [here](https://www.8x8.com/products/devices/compatibility).

- Phones not purchased from 8x8 must follow the procedures below.
- Cisco 3PCC phones that are not listed in the link provided are considered 3rd party non-supported SIP devices.

To ensure supported CISCO 3PCC devices can be provisioned with 8x8, compatible and non-compatible Cisco Models are:

- **Compatible**: Cisco 3PCC series 7800, 8811, 8841, 8851 and 8861 Product Name will have 3PCC e.g. **CP-88xx-3PCC** or **CP-78xx-3PCC** where **xx** is the full model as example 8841
- **Non-compatible**: **CP-88xx-K9** or **78xx-K9** are not compatible or supported by 8x8 VoIP Services. These are specific to Cisco Enterprise Models
- **How to Convert Cisco Models to compatible Firmware**: [Cisco how to guide converting models to supported firmware](https://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/unified-ip-phone-7800-series/guide-c07-742786.html). 8x8 cannot assist on converting. Consult Cisco.

## Procedure

### Identify the Product Name

From the Cisco phone, press the applications settings **Key ![Button.jpg](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/9961?sv=2026-02-06&spr=https&st=2026-11-03T22%3A20%3A40Z&se=2026-11-03T23%3A20%3A40Z&sr=c&sp=r&sig=7Mxg5sRnUYxiEicr4L7DM%2FP8%2F6YlAS5om%2Bu4nJ4lTso%3D)**

1. Navigate to **Status** > **Product information** > **Product Name** confirm **3PCC** shows, example CP-8841-3PCC.

If the display is not showing 3PCC, refer to the Cisco documents to properly identify and update to a supported firmware version. For more information, see [What is the recommended firmware for 8x8 phones and analog adapters?](/support/docs/what-is-the-recommended-firmware-for-8x8-phones-and-analog-adapters)

### Provision the Phone

1. Connect the phone to the network and power it on. (If you will be using a computer to complete provisioning setup, ensure the phone and computer are on the same VLAN/subnet.)
2. Verify that the device has a valid factory-installed device certificate: **Applications** > **Status** > **Product Info** > **Certificate**. Scroll down to look for the message ***Certificate: Installed***. If you do not see this, the phone cannot be provisioned for use with 8x8.
3. Factory reset the phone: **Settings** > **Device Administration** > **Factory Reset** > **OK**. ***Note****: Ensure the phone and computer are on the same VLAN/subnet to complete the following steps.*
4. On the device, press **Settings** > **Status** > **Network Status** > **IPv4 Status**
5. Note the phone's **IP address** and enter it on a web browser.

> [!NOTE]
> Note:
> 
> Most browsers use HTTPS by default, but when factory reset Cisco devices use HTTP so you should enter something like this:
> 
> - http://10.0.0.1

http://10.0.0.1
6. At the top right click **Admin Login** > **Advanced**
7. Click on **Voice** > **Provisioning**
8. For *Profile Rule* insert https://cisco.8x8.com/cisco/$MA.cfg ![Cisco_8861_Standard_Provisioning-600x363.png](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/9962?sv=2026-02-06&spr=https&st=2026-11-03T22%3A20%3A40Z&se=2026-11-03T23%3A20%3A40Z&sr=c&sp=r&sig=7Mxg5sRnUYxiEicr4L7DM%2FP8%2F6YlAS5om%2Bu4nJ4lTso%3D)
9. Click **Submit All Changes** (Phone should reset).
10. Once the phone boots back up, manually reboot the phone again.
