Voice SMS

The "Voice" solution is an automated service for the delivery of voice messages synthesized from text or pre-recorded voice messages.  

The user can create and manage voice campaigns, monitor campaigns, track spending, interaction with the end user (interactive campaigns), and service behavior. The voice module is made up of two sections: Campaigns and Create a campaign, each described in the following chapters.


The Campaigns tab shows a list of campaigns already created, allowing you to preview and manage them. Campaigns are displayed in chronological order, most recent first. By clicking the Modify button, the order will be changed and the old campaigns will be displayed first.

Depending on the progress and settings, the campaign can have one of the following states:

  • Draft – Campaign creation started, but not finished.
  • Scheduled – Campaign scheduled for a future time.
  • In Progress – Campaign currently running.
  • Failed – The campaign could not be started.
  • Paused – Campaigns paused.
  • Canceled – Canceled campaigns.
  • Active – Active campaigns.
  • Finished – Campaigns completed.

Depending on your state, each campaign could be:

  • paused.
  • Duplicate, creating a new campaign with the same settings as an existing one.
  • View, ie visible, but also to edit the campaign.
  • Deleted.

filter and search

The campaigns listed in a campaign section can be filtered or searched. Filtering is done using the dropdown menu, as shown in the figure below.

The user can check the status they are interested in and click Apply. To find the campaign by name, the user must use the search option available by clicking on the magnifying glass button and entering the name of the campaign. 

campaign details

Individual voice campaign statistics are available by selecting the campaign row and clicking the campaign name or the view campaign details icon.

The available statistics show: 

  • Campaign completion status. 
  • Average duration of calls with minimum and maximum values. 
  • Answered calls versus live calls. 
  • Actual cost and estimated cost. 
  • Number of voice messages sent. 
  • Total time of the call. 
  • GSM/Landline phone ratio. 
  • Distribution by reason of error: BUSY, NO ANSWER, NOT DELIVERABLE. 
Furthermore, it is possible to preview the voice file used for the selected campaign.

Create a campaign

To create a voice campaign, the user must select the Create campaign tab. The page for creating voice campaigns is made up of:

  • The Create Campaign form, where the user enters all relevant data for a campaign.
  • The Alerts and Tips section at the bottom right of the screen provides guidance through the campaign creation process.

Steps to create a campaign:

  1. Campaign name : The user must enter the name of the voice campaign. This name will be used to monitor and manage the campaign. 
  2. Countryside "For”: The user must choose the recipients of the campaign using one of the following possibilities: 
  3. Write recipient numbers (up to 15K) 
  4. Upload File: Select a file from your PC. 
  5. Add one of the subscriber lists: Choose the existing subscribers from the dropdown list. 
  6. Countryside "From”: The user must choose the sender of the campaign from the dropdown menu. Available numbers are white labeled caller ID numbers.

Account administrators are in charge of creating or changing caller ID numbers. 

4. Programming Options: The user can not only define the start and end date of the campaign, but also the time window of the campaign. By selecting the start and end time it is possible to place a call during a specific time of the day and avoid calls late at night, for example. The system allows you to set the correct time zone. In case the date and time are not set, the campaign will start immediately (according to the specified time zone) after the user presses the button.

5. There are two ways to create a voice message: Synthesized with Text-2-Speech, then upload the file. With Text-2-Speech, the user converts text messages into voice messages. The text must be entered in the message field and the language must be selected from the dropdown menu. Voice preview is available by pressing the Preview button.

File Upload allows the user to upload the file from their PC. The UPLOAD FILE option must be selected to select and upload the file. Audio files up to 4MB in size and in various audio formats are supported. 
  1. Basic customer interaction is available right now: 
  2. Call transfer: Allows you to define a number to which the call will be forwarded in case defined DTMF response codes have been entered. 
  3. Add contact list: Based on defined DTMF response codes, send a contact to a specific list. 
  4. Remove from contact list: Based on defined DTMF response codes, remove the contact from the specified list. 

The user could open a field + ADD A TRIGGER FIELD and create interaction patterns.

It is possible to create different action groups depending on whether the response code is identical to any dtmf key. 

Action groups are linked to certain actions: code transfer, add or remove from contact list. The user could save the draft campaign and continue working on it later, or launch the campaign according to the date and time selected in step 4.

Alerts and Advice Form

The user must check the alerts and advice form to obtain additional information and advice about the steps and actions for the creation of the campaign.
