Document Purpose

This document details a complete integration blueprint to deploy a Yeastar TA800 8-Port FXS gateway alongside a Yeastar P-Series PBX without using extension licenses. It supports bidirectional discrete public routing, direct internal dialling shortcut codes, and accurate internal Caller Line Identification (CLI) presentation.

System Requirements

• A static local IP address assigned to the Yeastar P-Series PBX.
• A static local IP address assigned to the Yeastar TA800 Gateway.
• An active SIP Peer Trunk configured between both systems (e.g., named TA800_Gateway on the PBX and P_Series_PBX on the gateway).

Part 1: External Inbound Call Routing (Public DIDs to Ports)

Step 1.1: Add the DIDs to your Main SIP Trunk (P-Series PBX)

1. Log into your P-Series Management Portal.
2. Go to Extension & Trunk > Trunk and click Edit on your main external VoIP provider trunk.
3. Click the DIDs/DDIs tab at the top of the configuration window.
4. Click Add and enter your 8 public phone numbers.
5. Click Save.

Step 1.2: Create 8 Inbound Routes (P-Series PBX)

Repeat these configuration steps for each of your 8 external numbers:

1. Go to Call Control > Inbound Route and click Add.
2. Name the route clearly (e.g., Inbound_Port_1, Inbound_Port_2, etc.).
3. In the DID Pattern field, type the specific public phone number you want assigned to that target port.
4. In the Member Trunk section, select your main external provider trunk.
5. Scroll down to the Default Destination section and configure:

• Destination: Trunk
• Trunk: Select your TA800_Gateway peer trunk.

6. Click Save and Apply.

Step 1.3: Catch and Separate the Public Numbers (TA800 Gateway)

1. Log into your TA800 Web GUI.
2. Navigate to Gateway > Route Settings > IP→Port and click Add New Route.
3. Configure the routing rule:

• Route Name: Catch_Number_1
• Simple Mode: No
• Call Source: Select your P_Series_PBX peer trunk.
• DID Number / Dial Pattern: Type the exact phone number matched in Step 1.2.
• Call Destination: Select FXS Port 1.

4. Click Save.
   (Repeat for ports 2 through 8, matching each unique public number to its physical port).

Part 2: Internal Call Routing (PBX Extensions to TA800 Ports)

Step 2.1: Create an "Internal-to-Gateway" Outbound Route (P-Series PBX)

1. In your P-Series Management Portal, navigate to Call Control > Outbound Route and click Add.
2. Configure the route properties:

• Name: Internal_to_TA800
• Dial Pattern: *80[1-8] (Matches *801 through *808)
• Strip: 0

3. Scroll down to Select Trunks and move your TA800_Gateway peer trunk into the Selected column.
4. Scroll to Select Extensions and move your internal P-Series extensions or extension groups into the Selected column.
5. Click Save and Apply.

Step 2.2: Route the Internal Codes to Physical Ports (TA800 Gateway)

1. In your TA800 Web GUI, navigate to Gateway > Route Settings > IP→Port and click Add New Route.
2. Configure the rule for the first port:

• Route Name: Internal_Port_1
• Simple Mode: No
• Call Source: Select your P_Series_PBX peer trunk.
• DID Number / Dial Pattern: *801
• Call Destination: Select FXS Port 1.

3. Click Save.
   (Repeat for the remaining 7 ports, matching *802 to Port 2, up to *808 to Port 8).

Part 3: Internal Analog Outbound Routing & Internal CLI Mapping

Step 3.1: Configure Outbound Caller ID Presentation (TA800 Gateway)

1. In your TA800 Web GUI, navigate to Gateway > Route Settings > Port→IP and click Add New Route.
2. Configure the outbound rule for the first port:

• Route Name: Outbound_Port_1
• Simple Mode: No
• Call Source: Select FXS Port 1.
• Dial Pattern: .
• Call Destination: Select your P_Series_PBX peer trunk.
• From User / Caller ID: Type *801

3. Click Save.
   (Repeat this step 7 more times for Ports 2 through 8, changing the Route Name, Call Source Port, and modifying the Caller ID field sequentially to match *802 through *808). Click Apply Changes when finished.

Step 3.2: Configure the Internal Inbound Route Engine (P-Series PBX)

1. In your P-Series Management Portal, navigate to Call Control > Inbound Route and click Add.
2. Configure the route properties:

• Name: TA800_Internal_Transit
• DID Pattern: .
• Member Trunk: Select your TA800_Gateway peer trunk.
• Destination: Select By Dialled Number (or use regular routing settings to point incoming dialled extensions straight through).

3. Click Save and Apply.

Operational Verification

• External Inbound: A call to Public Number #3 passes over the peer trunk, matches pattern #3 inside the gateway, and rings the phone on hardware Port 3.
• Internal Inbound: An IP desk phone dials *803. The PBX pushes the call down the peer trunk, the gateway matches the string, and rings hardware Port 3.
• Internal Outbound with Custom CLI: An analog device on Port 3 dials internal extension 105. The gateway tags the call stream source header as *803 and shoots it to the PBX. Extension 105 rings, displaying *803 on its screen. If Missed, the user can hit redial to dial *803 straight back.
