# Configuring an Avaya J Series Phone

Avaya J-Series IP phones are widely used in business communications environments.

This guide explains how to **manually** register an **Avaya J139 IP Phone** with PortSIP PBX in **3PCC mode**. In this mode, the phone is configured for use with a third-party SIP platform rather than being provisioned by an Avaya PBX.

This guide is intended for administrators who need to manually configure an Avaya J139 IP Phone for use with PortSIP PBX.

### Version Requirements

Before you begin, ensure that your environment meets the following minimum version requirements:

| Component                     | Minimum Version |
| ----------------------------- | --------------- |
| PortSIP PBX                   | v22.6.1         |
| Avaya J-Series phone firmware | 4.1.11.0.9      |

> **Important**
>
> Upgrade PortSIP PBX and the Avaya J-Series phone firmware to the minimum versions listed above or later before following this guide.
