In the VoipNow interface, follow the steps below:

Set the password for the diagnostic extension. The Diagnostic Extension Password (*011) can be enabled server-wide from the Unified Communications → Zero Priority → Monitoring tab. Fill in the Password control field and confirm it in the Confirm password control text box.
Install a Cepstral voice engine.

Please note that VoipNow supports only Cepstral 5.1.

For this feature to work, you need to ensure that there is at least one Cepstral voice engine installed on your server.

Download a voice from this page (e.g. Cepstral_Allison_i386-linux_5.1.0.tar.gz).
Make sure you download either the i386 or x86_64 version, depending on your OS.
After downloading it, open a server console window, log in as root using a SSH client (e.g. Putty) and run:

tar zxvf Cepstral_Allison-8kHz_x86-64-linux_5.1.0.tar.gz
cd zxvf Cepstral_Allison-8kHz_x86-64-linux_5.1.0
./install.sh

Follow the messages on the screen and agree to the terms.
The voice is going to be installed by default in the /opt/swift/voices folder.
To verify what voices you have installed you can use the /usr/local/voipnow/admin/bin/cepstrallic5 tool with --get parameter.

To access this extension, dial *011. You will be asked for the password that you have set earlier.

VoipNow will announce the values of the following parameters:
