Prerequisites

Make sure that you have completed the corresponding settings shown below according to the network environment of Grandstream IP phone and Yeastar PBX.

Network Environment Setting
Local Network Register extension in the same subnet /
Register extension in different subnets Enable the Remote Registration feature for the extension (Path: Extension and Trunk > Extension > > Security > SIP Security > Allow Remote Registration).
Remote Network Register extension using Yeastar FQDN
Register extension using Public IP address / External Host domain name
  • Configure PBX network for remote access by a public IP address or by an external host domain name.

Step 1. Gather registration information on Yeastar PBX

Log in to PBX web portal, gather the following information for extension registration.

Information Instruction
Extension information Go to Extension and Trunk > Extension > > User > Extension Information, note down the following information:
  • Extension Number
  • Registration Name
  • Registration Password
Transport protocol Go to Extension and Trunk > Extension > > Advanced > VoIP Settings > Transport, note down the transport protocol of the extension.

In this example, the extension use UDP transport protocol.

Note:
  • If the extension uses TCP transport protocol, make sure that the SIP TCP port is enabled on the PBX, or the registration would fail (Path: PBX Settings > SIP Settings > General > Basic).

  • If the extension uses TLS transport protocol, make sure that the TLS is enabled on the PBX, or the registration would fail (Path: PBX Settings > SIP Settings > TLS).
PBX IP address or domain name

Scenario: Register extension in local network

In this scenario, you can directly utilize the PBX's private IP address for extension registration.
Note: This topic provides the configuration example based on this scenario, where the PBX's private IP address is 192.168.28.39.

Scenario: Register extension remotely using Yeastar FQDN

Go to System > Network > Yeastar FQDN, note down the PBX's Fully Qualified Domain Name (FQDN).

Scenario: Register extension remotely using Public IP address / External Host domain name

Go to System > Network > Public IP and Ports, note down the PBX's public IP address or external host domain name.
SIP registration port

Scenario: Register extension in local network

Go to System > Network > Service Ports, note down the SIP registration port corresponding to the extension's transport protocol.

In this example, we use the SIP UDP port 5060.

Scenario: Register extension remotely using Yeastar FQDN

Go to System > Network > Yeastar FQDN > Features > SIP Access, note down the SIP registration port corresponding to the extension's transport protocol.

Scenario: Register extension remotely using Public IP address / External Host domain name

Go to System > Network > Public IP and Ports > Public Ports, note down the SIP registration port corresponding to the extension's transport protocol.

Step 2. Register extension on Grandstream IP phone

  1. Log in to the web interface of the Grandstream IP phone.

    1. In the browser's address bar, enter the IP address of the IP phone.
    2. Enter the username admin and the associated password.
    3. Click Login.
  2. On the left navigation bar, go to Accounts > Accounts, and select an available account.

  3. In the General Settings tab, complete the registration configurations.

    • Account Active: Select the checkbox to activate the account.
    • Account Name: Enter the name associated with the account, which will be displayed on the phone screen.
    • SIP Server: Enter the IP address / domain name of the PBX along with the SIP registration port.
