Yeastar TG Gateway Integration Guide

Introduction

This guide provides a configuration example to describe how to extend GSM/3G/4G trunks for Yeastar P-Series PBX System using the Yeastar TG Gateway.

Background

The instructions provided in this guide are based on the following test environment:

There are two SIM cards installed in Yeastar TG400 GSM Gateway. The following table shows mobile number prefixes of the two carriers.

Diagram Description: A network diagram illustrating the connection between Yeastar P-Series PBX System and Yeastar TG400 GSM Gateway. It shows Carrier A and Carrier B connecting to SIM Card 1 and SIM Card 2 respectively within the TG400 Gateway. A SIP Trunk connects the TG400 Gateway to the Yeastar IPPBX, which is part of a Local Network with extensions Ext. 2000 and Ext. 2001.

Objectives

This guide provides guidance based on the above scenario to help you achieve the following objectives:

• Connect Yeastar P-Series PBX System and Yeastar TG400 Gateway
• Make Outbound Calls through a Designated GSM Trunk
• Route Calls from Different Carriers to Different Destinations

Chapter 1: Connect Yeastar P-Series PBX System and Yeastar TG GSM Gateway

This topic introduces the steps to connect Yeastar P-Series PBX System and Yeastar TG400 via SIP peer trunks. After the two devices are connected, GSM trunks are extended on the Yeastar P-Series PBX System.

1.1 Create a SIP peer trunk on Yeastar IPPBX

1. Log in to the PBX management portal, go to Extension and Trunk > Trunk, click Add.
2. Configure the trunk basic settings:
   • Name: Enter a name to help you identify it. For example, TG400.
   • Trunk Status: Select Enabled.
   • Select ITSP Template: Select General.
   • Trunk Type: Select Peer Trunk.
   • Transport: Select UDP.
   • Hostname/IP: Enter the IP address of Yeastar TG400 gateway. In this example, enter 192.168.6.200.
   • Port: Enter the SIP port of Yeastar TG400 gateway. In this example, enter the default port 5060.
   • Domain: Enter the IP address of Yeastar TG400 gateway. In this example, enter 192.168.6.200.
3. Click Save and Apply.

Wait for seconds and check the trunk status on the Trunk page. If the status shows ✔️, Yeastar IPPBX is connected to the Yeastar TG400 gateway.

1.2 Create a SIP peer trunk on Yeastar TG400 Gateway

1. Log in to the gateway web interface, go to Gateway > VoIP Settings > VoIP Trunk, click Add VoIP Trunk.
2. In the pop-up window, configure the following settings:
   • Trunk Type: Select Peer Trunk.
   • Type: Select SIP.
   • Provider Name: Enter a name to help you identify it.
   • Hostname/IP: Enter the IP address of Yeastar IPPBX and the SIP port. In this example, enter 192.168.6.124 and the default SIP port 5060.
3. Click Save and Apply Changes.
4. Wait for seconds and check the trunk status on the Status > System Status > Trunk Status page. If the status shows "OK", Yeastar TG400 Gateway is connected to the Yeastar IPPBX.

Chapter 2: Make Outbound Calls through a Designated GSM Trunk

Many carriers have call plans that let you make free or low-cost calls between other numbers through the same carrier network. The following guides you how to make outbound calls through designated GSM trunks to save call charges.

Scenario

In this scenario, you will route outbound calls through designated GSM trunks as follows:

Diagram Description: A network diagram showing the flow for making outbound calls. It depicts dialing a number with prefix 92 (e.g., 921234567) through Carrier A and SIM Card 1, routed via the Yeastar TG400 Gateway and SIP Trunk to the Yeastar IPPBX, and then to an extension. Similarly, dialing a number with prefix 10 (e.g., 108192837) uses Carrier B and SIM Card 2.

Step 1: Create an outbound route on Yeastar IPPBX

To allow PBX users to call through the Yeastar TG400 gateway, you need to create an outbound route on Yeastar IPPBX.

1. Log in to the PBX management portal, go to Call Control > Outbound Route, click Add.
2. Configure the following settings for the outbound route and leave other settings as default:
   • Name: Enter a name to help you identify it. For example, TO-TG400.
   • Dial Pattern: Set the dial patterns according to your needs. In this example, set Pattern to X., which means that users can dial any number without limitation.
   • Trunk: Select the SIP peer trunk that is connected to the Yeastar TG400. In this example, select the trunk TG400.
   • Extension/Extension Group: Select the extensions that are allowed to make calls through this outbound route. In this example, select all the extensions.
3. Click Save and Apply.

Step 2: Create two 'IP to Mobile' routes on Yeastar TG400

Create an 'IP to Mobile' route for carrier A, and create another one for carrier B. These two routes will match the dialed numbers from PBX and send numbers out through designated GSM trunks.

1. Log in to the gateway web interface, go to Gateway > Route Settings > IP to Mobile, click Add IP to Mobile Route.
2. In the pop-up window, configure the route, then click Save and Apply Changes. The following table shows the required configurations for carrier A and carrier B.

Note: If you want to match any incoming calls, you need to set DID Number to . (dot), or outbound calls would fail. ?

Step 3: Make test calls from Yeastar IPPBX

Examples:

• Dial number 921234567, the call will be made through GSM trunk1.
• Dial number 108192837, the call will be made through GSM trunk 2.

Chapter 3: Route Calls from Different Carriers to Different Destinations

When external users call to GSM trunks of different carriers, the calls will reach different destinations. This section gives instructions based on the following scenario.

Scenario

Diagram Description: A network diagram illustrating inbound calls from external users to GSM trunks. It shows a call to GSM trunk 1 (9218273) via Carrier A and SIM Card 1 reaching Extension 2000 on the Yeastar IPPBX. A call to GSM trunk 2 (1019238) via Carrier B and SIM Card 2 reaches Extension 2001 on the Yeastar IPPBX.

Step 1: Create two 'Mobile to IP' routes on Yeastar TG400

Create an 'Mobile to IP' route for carrier A, and create another one for carrier B.

1. Log in to the gateway web interface, go to Gateway > Route Settings > Mobile to IP, click Add Mobile to IP Route.
2. In the pop-up window, configure the route, then click Save and Apply Changes. The following table shows the required configurations for carrier A and carrier B.

Note: The hotline number will be sent to the PBX as a DID number, which can be configured on PBX's inbound route to distinguish calls from different carriers. ?

Step 2: Create two inbound routes on Yeastar IPPBX

Create two inbound routes to distinguish calls from carrier A and carrier B, and route calls to different destinations.

1. Log in to the PBX management portal, go to Call Control > Inbound Route, click Add.
2. Configure the following settings for the inbound route and leave other settings as default, then click Save and Apply. The following table shows the required configurations for carrier A and carrier B.

Step 3: Make test calls to the GSM trunks

• Dial the number of GSM trunk1 (9218273), the call will be routed to extension 2000.
• Dial the number of GSM trunk 2 (1019238), the call will be routed to extension 2001.
