Step 4 - Configure SIP Trunking

Important: Before Proceeding with this step please ensure you have completed Step 3: Update Network Settings and that EasySBC is in a Running state.

Purpose of this step: In this step you will configure SIP trunking between your Internal VoIP server and your SIP Trunk Provider.

Required for this step: 

  • SIP Address for your SIP Trunk Provider (usually sip.<providers domain>.com or an IP address)
  • The SIP Transport for your Provider's connection TCP or UDP (usually UDP)
  • Is Registration is required? If Yes, Registration Details will be needed. You will need a Username, Password and Registration Address (domain or IP address)
  • SIP Address for your Internal VoIP Server (IP Address or FQDN)
  • The SIP Transport for your Provider's connection TCP or UDP (usually UDP)
  • You must be logged into the EasySBC Web Management Interface

Once you have the above information you can proceed onto the next steps to start configuring you SIP trunk connection.

Note: By now we are sure you are getting comfortable with the navigation of the EasySBC settings, so we'll miss out the basic pointers and get straight to the task at hand. If you need any help with navigation please revisit steps 1 to 3 in the Configuration section.

Navigation: Navigate to the Settings menu, and under Active Feature Modules please select EasySBC.

You will be presented with the following screen:

Configure the SIP Trunk Provider section with the correct settings, and if SIP Registration is required pleased add that information too, remembering the check the Enabled checkbox.  If you don't know, or weren't provided with a Realm then please leave this blank.

Add the details of your Internal VoIP Call Server and add the Transport type.  Click on the Update button and you're done.

Hint: If you are using SIP Registration  to your Trunk Provider you can verify the status of the registration.

Here's how: From the Home screen, navigate to Status. Under Real Time Information you will see SIP Trunk Registration.  If you select this option you will see the SIP Trunk registration status.  For more information go here

You are now ready to move onto the next section which will tighten up the Network Access to the EasySBC.  The next step is Step 5: Add Network Access Rules
