Mass Calling

Has anyone used a service where you can upload a “greeting/message” and input a group of numbers and the system would call the numbers and answer with the greeting/message? for future outages/maintenance or other reasons.

We use for this. Not integrated into Sonar, but we have a custom report that gives us the fields we need which we upload to phonevite.

Phonevite calls each customer and plays a message. It also sends them an email with a link to play the message.
