This sample is probably the simply form of a
voicemail system. It is basically an answering machine. Other voice
mail samples will further extend the feature set, such as adding
more mailboxes and voicemail to email.
The call flow is straightforward for an
answering machine applications. It
consists of one Record Element and one Prompt
Element. A record element sets the system in recording mode. A
caller can end the pound key (#) or simply hang up to finished
the recording. A Prompt Element plays the prompts
defined in the element.
You can open this design by selecting File > Samples >
Voicemail from the program main menu.
A record element (Leave Message element
in the call flow diagram) requires audio message to
prompt a caller to start recording. You can use three types of
prompts described in the Auto Attendant sample.
Here we are going to use a text-to-speech engine to generate
an audio file. Please note that Voicent
Natural Text-to-Speech is a separate product. The default
text-to-speech engine is a free one from Microsoft.
Select Audio > Create Audio by
Text-to-Speech... from the program main menu. Simply type in
any text, and click Save to Wave... button.
To set the newly generated audio file for an element
prompt, right
mouse click on an element, then choose Properties...
from the popup menu. Click the Prompt tab, then click the
New... button. Click the Browse button to select the newly
created audio file.
You can use the sample application as is. To deploy the
application, select Deploy > Submit to Gateway... from
the program main menu. If the menu item is grayed out, select
Validate... first.
If you have multiple IVR application deployed, please see
IVR select application for more information.
Once deployed, restart the gateway to have the
changes to take effect.
When an incoming call is answered by the
gateway, the application will execute the record element,
which first plays the Prompt, and
then wait for caller to record his or her message. If the caller presses
#, it then
executes the Prompt Element, which plays the thank-you
message.
The voice mail message is saved on your
computer as an audio file. You can find the audio file under
the folder:
C:\Program
Files\Voicent\Gateway\apps\<deployment name>\recording
The
Voicemail
to email sample adds more
features to this simple voicemail system.
