Perform the procedures in the following workflow to configure the
device for a basic SIP Trunk to SIP IP PBX application. The resulting configuration connects an existing LAN-side IP PBX host to a WAN-side Border Element host, such that internal callers can reach an outside Internet Telephony Service Provider (ITSP) and vice-versa. (Provisioning for a specific dial plan is beyond the scope of this workflow.)
For a complete illustration of the entire provisioning process, including sample outputs of the Setup Wizard, Network Interface provisioning, Static Route provisioning, and the Easy Configuration Wizard, refer to SIP Trunk Configuration for IP PBX Deployment.

Prerequisites
- Completion of the initial setup procedures per the Workflow for Initial Setup. This includes physically installing the device, configuring the initial platform settings (Setup Wizard), and installing the license.
- Login access to the WebUI as user administrator (admin)
Workflow
Use this procedure to manage the way the
within the
device interfaces with the external network.
The
supports:
- four system-created logical interfaces: the Administrative IP, Ethernet 1 IP, Ethernet 2 IP, and Ethernet 3 IP interfaces
- user-created VLAN logical sub-interfaces
The following table explains the nature of each of the logical interfaces.
Logical Interfaces for a SIP to SIP IP PBX Application
| Logical Interface | When and How Configured | Purpose |
|---|
| Admin IP | Set during the execution of the Setup Wizard1, under Swe-Edge Settings: Mgmt Host IP. | Provides access to the WebUI of the | Spacevars |
|---|
0product | device |
| Ethernet 1 IP | Configured manually. | Provides access to the LAN-side IP PBX |
| Ethernet 1.2626 IP | Configured manually. | Provides a VLAN logical sub-interface to the LAN-side IP PBX |
| Ethernet 2 IP | Configured manually. | Not used in this SIP to SIP IP PBX application |
| Ethernet 3 IP | Configured manually. | Provides access to the WAN-side Border Element (Internet Telephony Service Provider, ITSP) |
1 References to the Setup Wizard refer to the procedures in Running Setup Wizard, either for the
stand-alone or
High Availability deployment.
Start
- In the Web UI, click the Settings tab.
- Navigate to SBC > Networking Interfaces > Logical Interfaces.
Configure each of the logical interfaces per your network plan.
For field definitions, refer to Configuring and Modifying Logical Interfaces in the documentation.
Use this procedure to configure static routes required by your device to communicate with remote networks.
In a production environment, static routes are mainly configured for routing from a specific network to another network that can only be accessed through a gateway (for a single path access or default route). When planning your network, consider these factors:
- For smaller networks with just one or two routes, configuring static routing is preferable. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.
- For networks that have a LAN-side gateway on Voice VLAN or Multi-Switch Edge Devices (MSEs) with voice VLAN towards the SBC Edge, static routing configurations are not required.
In the following example, two static routes are defined:
- The first static route gives access to the SWe Edge WebUI through a VPN subnet.
- The second static route gives access to SIPP servers on the WAN side of the device.
Start
- In the Web UI, click the Settings tab.
- Navigate to SBC > Protocols > IP > Static Routes.
Configure each of the static routes per your network plan.
For field definitions, refer to Creating Entries in a Static IP Route Table in the documentation.
Run the Easy Config Wizard
Use this procedure to configure the basic call routing framework for a SIP Trunk to SIP IP PBX application.
The
WebUI includes an Easy Configuration Wizard, which enables end-users to
quickly configure settings for different deployment scenarios. Based on a template, you can configure items including:
- an endpoint, with a defined user and provider
- a routing scheme, with a routing configuration applied to the scenario
- a country, with tone table parameters and emergency numbers for the chosen country
| Info |
|---|
|
Once you complete the Easy Config Wizard, you must apply additional provisioning before making calls. This includes changing entries to the Transformation Tables, Signaling Groups and Routing Tables according to the network topology and dialing plan unique to your particular deployment. |
Start
- In the Web UI, click the Tasks tab.
- Navigate to SBC Easy Setup > Easy Config Wizard.
From the Step 1 menu, complete the fields for Scenario Parameters, SIP Trunk and IP PBX.
For the SIP Sessions parameter, enter a value based on the license allocation for concurrent call sessions you ordered when you placed your order.
For field definitions, refer to Configure a SIP Trunk With IP PBX in the documentation.
| Info |
|---|
|
The value entered for Scenario Description will be prefixed to all SBC configuration elements that the Easy Config Wizard creates. Example: If you enter SIP to SIP for the description, then the Call Routing tables for this deployment will be SIP to SIP: From IP PBX and SIP to SIP: From SIP Trunk. |
Example:
| Panel | Area | Field | Value |
|---|
| Scenario Parameters |
| Application | SIP Trunk ↔ IP PBX |
| Scenario Description | SIP to SIP |
| Telephone Country | United States |
| Emergency Services | None |
| SIP Properties | SIP Sessions | 100 (or whatever number you have licensed) |
| SIP Trunk |
| Name | Other SIP Trunk |
| IP PBX |
| Type | Other IP PBX |
- Click Click Next.
From the the Step 2 menu, complete the fields for SIP Trunk and IP PBX.
For field definitions, refer to Configure a SIP Trunk With IP PBX in the documentation.
Example:
| Panel | Field | Value |
|---|
| SIP Trunk: Other SIP Trunk | Border Element Server | 10.230.98.141 |
| Protocol | UDP |
| Port Number | 5060 |
| Use Secondary Border Element Server | Disabled |
| IP PBX: Other IP PBX | Host | 10.230.98.142 |
| Protocol | UDP |
| Port Number | 5060 |
| Use Secondary Server | Disabled |
- Click Click Next.
- From the the Step 3 menu, examine the SBC Setup Configuration Summary.
Click Previous to make a change in a previous step.
Click Finish when you are satisfied with the entries. - After clicking clicking Finish, click OK when you are ready to continue.
Note that after clicking Finish, a confirmation message appears stating that a standard configuration is being applied and that you will need to configure additional parameters (especially for Transformation Tables, Signaling Groups and Routing Tables) before making calls. Click OK when you are ready to complete the Easy Configuration process.
