What is Voice Broadcasting?

Voice broadcasting is a way to send a recorded audio message to a group of phone numbers within a short period of time.

It's similar to an email broadcast or a text broadcast in terms of sending a mass notification.

How it works

There are 4 simple steps.

1) Set up and verify your Caller ID so your contacts know who's calling

2) Upload your contact list as an excel file

3) Record your audio message over the phone or upload your recording

4) Send the calls now or at a specific date and time in the future

Is Voice Broadcasting Legal?

Yes, it is when complying with federal and state laws.

"Most recently, in 2012, the FCC revised its TCPA rules to require telemarketers (1) to obtain prior express written consent from consumers before robocalling them, (2) to no longer allow telemarketers to use an "established business relationship" to avoid getting consent from consumers when their home phones, and (3) to require telemarketers to provide an automated, interactive "opt-out" mechanism during each robocall so consumers can immediately tell the telemarketer to stop calling."
