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.

Step 4: Download the VoIPTools 3CX Relay (if required)

3CX permits one 3rd party application to communicate with the 3CX server at a time.  To overcome this limitation, VoIPTools created the 3CX Relay Service.  The Relay is a lightweight application that is installed directly on the 3CX server.  The Relay exposes the 3CX Call Control API (and other VoIPTools services) to all our applications, and manages requests and events between VoIPTools products and 3CX.  The Relay also makes it possible to install our VoIPTools products on a remote server (including over the internet).

1. If you have not previously installed the Relay on your 3CX Server, you can download the Relay installer by clicking on the Download Relay button. The Relay must be installed directly on the 3CX server.

2. If you are installing ‘3CX Call Router’ directly on the 3CX server, you can install the Relay simply by clicking the Install/ Upgrade Relay button and following the Relay install instructions.

If you have already installed the Relay, you need not install it again unless a newer version is required.

Step 5: Test Relay Settings

1. In the Relay Type drop down, select Legacy Relay for old Relay or New Relay for new Relay based on the 3CX version of your application.

Figure 2: Test VoIPTools 3CX Relay settings

If you choose ‘Relay Type’ as ‘Legacy Relay’ then ‘3CX Call Router’ will communicate with old Relay Service, and if you choose ‘New Relay’ then it will communicate with new Relay Service.

2. In the Relay Services Host field, enter “localhost” if installing ‘3CX Call Router’ on the 3CX server. If 3CX resides on a different server, enter the IP address or FQDN of the 3CX server.

3. In the Relay Services Port field, enter the value as 8700 for Legacy Relay or 8800 for New Relay.

The ‘3CX Call Router’ will take default port as 8700 for ‘Legacy Relay’ and 8800 for ‘New Relay’. If the default port number doesn’t appear automatically, you can manually enter the respective default port number.

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

5. 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 SQL Server is installed on a server other than the server where ‘3CX Call Router’ is installed, you will need to configure SQL Server to allow remote connections
