Create a Mass Calling System in 7 Steps

Learn how to create an effective mass calling system for large customer outreach.

Step 1) Visit SigmaVoice.com

Click the Sign Up button for a free trial of our mass calling service.

Step 2) Sign In To Your Account

In your account, you can set your Caller ID, create recordings, upload your contacts, send out your calls and view call reports.

Step 3) Set Your Caller ID

The Caller ID is one of your organization's phone numbers. This 10 digit phone number will be displayed to your contacts on their phone. Your organization name will be displayed as well for most of the calls.

Step 4) Create Your Recording

You can upload a voice recording file from your device or you can record your voice message by calling our dedicated recording line. Most recordings are between 30 to 60 seconds however your recording can be much longer if you want. We also have a free text-to-speech option.

Step 5) Upload Your Contacts

It's fast and easy to import your contacts into your Sigma Voice account. Our system accepts many 10 digit phone number formats. In addition to the phone number, you can also include the first name and last name of each contact. Our system automatically checks for and removes any duplicate phone numbers.

Step 6) Send Your Calls

You can schedule your calls to be sent at a future date and time or send the calls immediately. You can also choose how fast your calls are sent by selecting how many Sigma Voice phone lines you want to use. For example, you can send 1,000 calls in less than 1 hour using 50 phone lines.

Step 7) Call Report

The call report shows detailed information for each phone call. This includes the date and time of the phone call as well as if the call was answered by a human or a machine. The report also shows the length of each phone call.
