What is promotional voice SMS (voice broadcasting)?
Promotional voice SMS — also called voice broadcasting or OBD (outbound dialing) — is an automated bulk voice call that plays your pre-recorded or text-to-speech message to thousands of recipients at once. Instead of an agent dialing manually, the system dials your list, plays the audio, and can capture responses through the keypad.
It is one-to-many and automated, unlike a regular voice call which is one-to-one and manual. OBD simply describes the outbound-dialing engine that powers the broadcast. Voice is especially powerful in India, where roughly 90% of users are non-English speakers — a spoken message in Hindi, Tamil, Telugu, Bengali or any regional language lands far better than text, and reaches people who cannot read a promotional SMS. Pair it with a “Press 1” prompt and every campaign doubles as a lead-generation channel.
