Introduction #
3CX Auto Voicemail allows your staff to record personalized voicemail messages, and automatically play these messages when connected to a customer’s voicemail box.
Primarily envisioned for call center agents who are making outbound calls, when a call center agent is transferred to a customer’s voicemail box, the agent can select from a list of prerecorded messages and have 3CX leave the voicemail for them.
Having 3CX leave the voicemail has the following benefits: #
- Immediately disconnects the agent from the call, thus instantly making the agent available to place the next call.
- Relieves some of the tedium of leaving repetitious voicemails by having 3CX do it for you.
- Eliminates wasted time saying the same voicemail message over and over throughout the day.
- Ensures a consistent, carefully crafted voicemail is delivered every time.

Step 4: Test Relay Settings #

NOTE:
If the test was unsuccessful:

- confirm that you have entered the correct IP address / FQDN for the 3CX server.
- confirm that 3CX Auto Voicemail and the Relay are using the same port and protocol.
Step 5: Configure the database #
When configuring 3CX Auto Voicemail, 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 Auto Voicemail, 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 Auto Voicemail #
- In the Ready to Install window, click Install to start the installation of the ‘3CX Auto Voicemail’.
The application installation progresses.
- Once the installation is complete, check Launch 3CX Auto Voicemail check box and then click Finish. The 3CX Auto Voicemail configuration screen opens. If you want to simply close the installer without opening the configuration screen, then simply uncheck Launch 3CX Auto Voicemail check box and then click Finish
Step 7: Register your Software #
Registration is required to enable your software. Registering also makes it possible for VoIPTools to provide a replacement key if your license key is ever lost. Also, it enables VoIPTools to notify you of any product updates, and reminders if your key is reaching the renewal date.
To register, click the icon that appears on the desktop once the installation is successfully done.
- On the 3CX Auto Voicemail configuration screen, in the License tab, enter your registration information in all the required fields (Note the red dot denotes a required field).
