Introduction #
3CX Caller ID gives you complete Control Over Your Outbound ID Number. The application temporarily changes your extension’s outbound caller ID number making it simple for your call center agents to select the desired caller ID number before placing a call.
The selected caller ID may represent a specific organization or geographical region. Regardless of the purpose, you have complete control over your outbound caller ID number.
For example, to make calls on behalf of an organization, you can make the agent’s outbound Caller ID reflect the phone number of the selected organization. And, if your agent calls customers of a specific geographical region, you can match the caller ID with that of the customer’s region.

These include .NET Framework (Web Installer), SQL Server Express (Web Installer), and, SQL Server Management Studio.

- On the Select Installation Folder window, the Folder field displays the location where the ‘3CX Caller ID’ will be installed. Note that you cannot change the path.
- Click Next to continue with the installation.

Step 4: Test Relay Settings #
- In the 3CX Relay Services window, in the Relay Host field, enter the FQDN of your 3CX server.
- Enter 8801 in the Relay Port field.
- Enter the public key you took from VoIPTools Relay services in the Public Key text area.

- Click the Test Relay Settings to confirm ‘3CX Queues Wallboard’ can communicate with the Relay services running on the 3CX server.
- If the ‘3CX Queues Wallboard’ is successfully able to communicate with the Relay services that run on the 3CX server, a Success message box appears. Click OK. If the test fails, you will not be able to continue until communication with the relay is established.
- Click Next to continue with the installation.

NOTE:
If the test was unsuccessful:
- confirm you have the correct firewall port open (default TCP 8801) on the 3CX server and the firewall protecting the 3CX server.
- confirm that you have entered the correct IP address / FQDN for the 3CX server.
- confirm that 3CX Caller ID and the Relay are using the same port and protocol.
Step 5: Configure the database #
When configuring 3CX Caller ID, select an existing Microsoft SQL Server instance in your environment. The database server can be a remote SQL Server (How-to configure SQL Server to permit remote connections), or a local instance running on the VoIPTools server.
- On the SQL Database window, in the Server field, select the desired instance of SQL Server
NOTE:
We encourage you to use SQL Authentication rather than Windows authentication. Many of our tools leverage a Call Flow Designer (CFD) application running on the 3CX. Frequently our CFD applications require access to a SQL database. If the 3CX server and the database server are not in an Active Directory domain, Windows authentication will fail. To use SQL authentication, your SQL Server must be configured to run in “Mixed Mode”. If you installed SQL Server with one of our tools, we configure SQL in “Mixed Mode”.

- To use SQL Authentication, be sure to uncheck the Trusted Connection checkbox.
- In the Username and Password fields, enter valid SQL login account credentials
- To use Windows Integrated Authentication (not recommended), check the Trusted Connection (Windows integrated authentication) checkbox.
- In the Database field, the installer will automatically display the default database name. We encourage you to use the default name. If you are upgrading or reinstalling 3CX Caller ID, select the existing database name from the list.
- Click the Test Sql Connection button to confirm connectivity to SQL Server and then click Next to continue.

Step 6: Installing 3CX Caller ID #
- In the Ready to Install window, click Install to start the installation of the ‘3CX Caller ID’.

The application installation progresses.

- Once the installation is complete, check Launch 3CX Caller ID check box and then click Finish. The 3CX Caller ID configuration screen opens. If you want to close the installer without opening the configuration screen, then uncheck Launch 3CX Caller ID check box and then click Finish.
