IVR Blast / Outbound Dialing (OBD)
NobleStack's IVR Blast and Outbound Dialing platform lets you broadcast interactive voice calls to thousands of customers in a single click. From simple announcements to multi-level IVR surveys and call-patch campaigns, it puts high-volume voice engagement and detailed reporting in the hands of your marketing and support teams.
Voice Broadcasting That Gets Heard
Email and SMS can go unread, but a well-timed voice call cuts through. Our OBD engine delivers pre-recorded or dynamic voice messages at scale, captures customer responses through keypad input, and connects interested callers directly to your agents — turning a broadcast into a conversation.

How It Works
From Contact List to Campaign Report
Broadcast interactive voice calls to thousands of customers, capture what they press, and act on the responses the same day.
Upload
Load your audience
Import contacts from a file, your CRM, or the API. Duplicates are removed and DND numbers are screened before a single call is dialled.
Build
Design the voice flow
Record or synthesise prompts, then lay out single-level or multi-level IVR branches with keypress options, retries, and call-patch to an agent.
Blast
Dial at scale on schedule
Launch immediately or schedule inside permitted calling hours. Concurrency, pacing, and retry rules for unanswered calls are all yours to set.
Report
See who answered and pressed what
Live dashboards show attempts, connects, keypress breakdowns, and patch-through outcomes — exportable per campaign for follow-up.
