With 3CX Call Router it is simple to route inbound calls based on Caller ID.  This tool allows you to identify a caller based on any number of digits (not just area code) and route to a selected extension.  Further, you can optionally choose to route to different locations based on time of day.

For example, do you need to route sales calls based on geographical region to the correct salesperson?  Do you want a customer to always be routed to the same agent?  You can do that.  Need to route these calls to a different location outside of office hours?  You can do that too.  It’s all easily managed with a secured web portal using 3CX Call Router.

2). To maximize security, we strongly urge you to configure the Relay and 3CX Call Router to use of https (TLS encryption).  To use TLS security, ensure the Relay Port is set to 8801 and the Protocol to HTTPS.  However, if your Relay is not configured to use TLS encryption, change the Relay Port to 8800 and the Protocol to HTTP.

Figure 12: Relay Protocol

3). Click Test Relay Settings to confirm ‘3CX Call Router’ can communicate with the Relay services running on the 3CX server.

If the test was unsuccessful: 

(1) confirm you have the correct firewall port open (default TCP 8801) on the 3CX server and the firewall protecting the 3CX server.
(2) confirm that you have entered the correct IP address / FQDN for the 3CX server.
(3) confirm that 3CX Call Router and the Relay are using the same port and protocol.

4). If the ‘3CX Call Router’ 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.

Figure 13: Success message box

5). Click Next to continue with the installation.

Step 5: Configure the database

When configuring 3CX Call Router, 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.

1). On the SQL Database window, in the Server field, select the desired instance of SQL Server

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”.

Figure 14: SQL Authentication

2). To use SQL Authentication, be sure to uncheck the Trusted Connection checkbox.

3). In the Username and Password fields, enter valid SQL login account credentials

Figure 15: Configure Database

4). To use Windows Integrated Authentication (not recommended), check the Trusted Connection (Windows integrated authentication) checkbox.

5). 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 Call Router, select the existing database name from the list.

6). Click the Test Sql Connection button to confirm connectivity to SQL Server and then click Next to continue.
