  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 P560 PBX.

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.

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

Table 3.
Outbound Number Format Trunk Carrier
Number with prefix 92 GSM trunk 1 Carrier A
Number with prefix 10 GSM trunk 2 Carrier B

1. Create an Outbound Route on Yeastar P560 PBX

To allow PBX users to call through the Yeastar TG400 gateway, you need to create an outbound route on Yeastar P560.

  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.

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.

    Table 4.
    Setting Description For Carrier A For Carrier B
    Simple Mode To keep simple mode with basic settings or to expand more settings. No No
    Route Name Enter a name to help you identify it. To-CarrierA To-CarrierB
    Call Source Select the SIP trunk that is connected to Yeastar P560 PBX. SPS – P560 SPS – P560
    DID Number Enter the pattern or number to match dialed numbers from Yeastar P560.
    Note: If you want to match any incoming calls, you need to set DID Number to .(dot), or outbound calls would fail.
    		 Enter 92. to allow the numbers with prefix 92. Enter 10. to allow the numbers with prefix 10.
    Call Destination Select the GSM trunk that will be used to call out. Mobile – Trunk1 Mobile – Trunk2

    Figure 2. 'IP to Mobile' route for carrier B

3. Make test calls from Yeastar P560 PBX

Examples:

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

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.

Table 5.
Carrier Trunk Destination
Carrier A GSM trunk 1: 9218273 Extension 2000
Carrier B GSM trunk 2: 1019238 Extension 2001

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.
