What is OBD

Automated voice calls that people actually listen to

OBD (outbound dialing) sends a pre-recorded voice message to a list of mobile or landline numbers automatically. It is also called voice broadcasting, bulk voice calls or automated voice calls.

Voice works where text does not: for customers who prefer listening, who read little English, or who need an urgent reminder. Our OBD platform runs at scale, retries unanswered calls and records every keypress, so a voice campaign can also collect feedback, confirmations and leads.
