Introduction #
3CX Monitor is a perfect diagnostic tool for monitoring call progress from “dialling” to “disconnecting”. With this tool, you can see all the events of a call. You can follow the path the call took, and see a complete list of attributes.
Why 3CX Monitor? #
3CX Monitor was originally designed as a programmer’s tool for monitoring call progress from “dialing” to “disconnect”. We have found, however, that it’s also one of the great diagnostic tools for monitoring the legs of a call to troubleshoot call routing issues.
If you need to know how a call ended up at a particular extension, 3CX Monitor can help. If you need to know how long a call rang at each leg of the call, this is the best tool for the job. With this tool you can see all the legs of the call and all attributes of a call. It is great for CRM integration projects.

- On the Select Installation Folder window, the Folder field displays the location where the ‘3CX Monitor’ will be installed. Note that you cannot change the path. Click Next to continue.
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 Monitor’ can communicate with the Relay services running on the 3CX server.
- If the ‘3CX Monitor’ 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 FQDN for the 3CX server.
- Confirm that 3CX Monitor and the Relay are using the same port and protocol.
Step 5: Configure the database #
When configuring 3CX Monitor, 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
- In the Username and Password fields, enter valid SQL login account credentials
- 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 Monitor, 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 Monitor #
- In the Ready to Install window, click Install to start the installation of the ‘3CX Monitor’.
The application installation progresses.
- Once the installation is complete, check the Launch 3CX Monitor check box and then click Finish. The 3CX Monitor configuration screen opens. If you want to simply close the installer without opening the configuration screen, then simply uncheck Launch 3CX Monitor check box and then click Finish
Step 7: Register your Software #

Retention #
Retention screen enables you to configure delete policy settings. 3CX Monitor logs several “events” for each call. A highly active PBX could generate a large number of transactions in the events table. To minimize the disk space utilized, and to keep queries running quickly, it is recommended that you minimize the size of the events tables. To automatically delete old transactions, you can configure how often records are deleted, and what records are deleted based on the creation date.
If you enable ‘Delete Retention Policy’, the records will be deleted based on the time zone of the server in which the relay is installed.
- Hover over the mouse on Settings tab and from the dropdown menu, select Monitor Settings.
- On the Settings menu, and in the Retention tab, under Delete Policy, check Enable Delete Policy check box if you want to enable the feature of automatically deleting old transactions.
