Introduction
Overview
When devices need to communicate using registered SIP accounts, you must deploy a SIP server and register the accounts on the devices. This document describes how to register industrial intercom devices to a PortSIP Server.
Applicable Models
All industrial intercom and SIP devices.
Prerequisite Preparation Tools
① One industrial intercom device (BHP-SOS16V as example), one PoE switch (or DC power supply), one PortSIP Server (installed on a Windows computer). Connect the device to the switch.
② One debugging computer connected to the same switch to ensure network connectivity between the computer and device.
Device and Computer Connection Diagram
Connect the BHP-SOS16V to the switch, connect the computer to the same switch, and install PortSIP Server on the computer. The connection diagram is shown in Figure 1.

Register to PortSIP Server
To register a device to PortSIP Server, you must first set up the server environment. This guide uses a Windows-installed PortSIP Server as an example.
Create Extensions on the Server
(1) Create an extension: Log in to the server Web interface, go to Call Manager — Extensions — click Add to create a new extension.
Enter the extension number and password to complete creation.

(2) Check domain and transport protocol: Go to Call Manager — Domains & Transports to view the SIP domain, transport protocol, and port number, as shown in Figure 3.

Register the Device to the Server
After creating the extension on the server, configure the device to register. Steps are as follows:
(1) Log in to the device: Enter the device IP address in a browser, log in with username and password (default: admin/admin).
(2) Go to the device Web UI: Line — SIP — Registration Settings, configure as shown in Figure 4:
- ① User Name, Authentication ID, Password: Use the extension number and password created on PortSIP Server;
- ② Server Address: Enter the PortSIP SIP domain;
- ③ Server Port & Transport: Enter the port and protocol (UDP as example);
- ④ Proxy Server & Port: Use the static IP of the PortSIP computer and matching port.

(3) After entering the information and ensuring network connectivity, the device Line Status will change to Registered, meaning the device is successfully registered to the SIP server.
