Hot Standby Configuration

Overview

Zycoo IPPBX is built on the Asterisk platform and supports the standard SIP protocol. It can connect to IMS SIP trunks from ITSPs (Internet Telephony Service Providers) as well as SIP endpoints.

This document provides instructions for configuring Hot Standby between two Zycoo IPPBX systems to ensure high availability.

Hot Standby Setup Guide

Prerequisites

Ensure the following conditions are met before beginning the configuration:

• Both devices must have the same system time

• Network configuration example used in this guide:

1. Configure the Master Device

Step 1.1: Log in to the Master Device

Log in to the IPPBX web interface using the admin account via IP address: 192.168.17.147

Step 1.2: Navigate to Hot Standby Settings

1. Navigate to Addons → Hot Standby

Step 1.3: Configure Master Mode

Configure the following parameters:

Step 1.4: Submit Configuration

After completing the configuration, click Submit to save the settings.

2. Configure the Slave Device

Step 2.1: Log in to the Slave Device

Log in to the IPPBX web interface using the admin account via IP address: 192.168.17.43

Step 2.2: Navigate to Hot Standby Settings

1. Navigate to Addons → Hot Standby

Step 2.3: Configure Secondary Mode

Configure the following parameters:

Step 2.4: Submit Configuration

After completing the configuration, click Submit.

Step 2.5: Verify Connection Status

Once the configuration is submitted, the Status should display Connected. This indicates that the Hot Standby feature has been successfully configured.

After successful configuration, return to the master device to configure extensions and other features.

3. Configure IP Phone Registration

Register your IP phone using the Virtual IP Address of the Hot Standby cluster:

4. Verify Failover and Switchback

Test Master/Slave Switchover

To verify that the Hot Standby configuration is working correctly:

1. Simulate a failure by either:

   • Unplugging the network cable from the master device's WAN port, or

   • Powering off the master device

2. Expected behavior: The system will automatically switch over to the slave device within 30 seconds.

Test Switchback

After the master device recovers:

1. Reconnect the network cable or power on the master device

2. The system will automatically register back to the master device after approximately 30 seconds
