Configuring Remote Extension with DDNS

 

Introduction

Yeastar S-Series IPPBX supports DDNS which allows us to register the remote extension without having a static public IP. Dynamic DNS or DDNS is a way to update the Domain Name System (DNS) to point to a changing IP address on the Internet in real time.

Yeaster S-Series IPPBX supports the following DDNS providers:

  • dyndns.org
  • freedns.afraid.org
  • www.no-ip.com
  • www.zoneedit.com
  • www.oray.com
  • 3322.org

 

Register DDNS Account

Register a DDNS account from above supported DDNS servers, and below I will use www.no-ip.com as the example.

If you already have an account please skip this step.

Step 1. Access to this link: https://www.noip.com/sign-up  to Create a free account

            

Step 2. Once you have created account successfully, please login to Create Hostname

You just need fill in the hostname and don't need care about the IPv4 Address.

 

If you create host successfully, you will see the following page, there is a free account so requires you to confirm your hostname every 30 days, if you don't want to be bothered you can upgrade account to Enhanced.

 

Step 3. Configure port forwarding on the router

Below is the setting page in a Linksys router, we must map UDP port 5060 and UDP port 10000-12000.

 

Configure DDNS on Yeastar S-Series
