NetLumen BlastX · Voice Blasting Services
Bulk voice calls and voice broadcasting
High-volume automated voice broadcast platform for sending pre-recorded or text-to-speech messages to thousands of recipients simultaneously with delivery tracking.
Overview
What is voice broadcasting?
Voice broadcasting — also known as bulk voice calling or voice blasting — delivers a recorded or computer-generated voice message to a large list of phone numbers at once. It is used for reminders, alerts, announcements and promotional calls.
NetLumen BlastX is a high-volume automated voice broadcast platform. Send pre-recorded audio or text-to-speech (TTS) messages, capture keypad (DTMF) responses, schedule campaigns, scrub numbers against DNC lists, retry unanswered calls automatically and review delivery reports. An API is available for triggering calls from your own systems.
In plain terms: BlastX sends a recorded voice message to many phone numbers at once, for reminders, alerts and announcements.

What BlastX does, feature by feature
Bulk Voice Broadcasting
BlastX places a bulk voice call campaign to a large contact list at once, so one recorded message reaches many numbers without an agent dialling each one. Buyers care because it frees staff from repetitive calling while keeping the message consistent for every recipient.
Text-to-Speech (TTS)
Text-to-speech converts a typed script into a spoken message, so you can launch automated voice calls without recording audio first. It is useful when wording changes often, because editing the text is quicker than arranging a new recording.
DTMF Response Capture
DTMF response capture records the keys a recipient presses on their phone keypad during the call, such as pressing a key to confirm or decline. This turns a one-way voice message into a simple way to collect answers you can act on afterwards.
Scheduled Campaigns
Scheduled campaigns let you prepare a voice broadcasting run in advance and set when it should go out. Teams can plan calls for hours when recipients are more likely to answer, without anyone needing to start the campaign by hand.
Delivery Reports
Delivery reports show what happened to each call in a campaign, such as whether it was answered or failed to connect. This gives you a clear record of who received the message and which numbers may need another attempt.
DNC Scrubbing
DNC scrubbing checks your contact list against do-not-call entries and removes matching numbers before a campaign runs. It helps you respect recipients' stated preferences and avoids spending calls on people who have asked not to be contacted.
Retry Logic
Retry logic automatically attempts a call again when the first try is not answered or does not connect. This improves the chance that your message reaches people who were busy, without staff having to rebuild the list manually.
API Access
API access lets your own software start campaigns and collect results from BlastX without someone logging in to do it. Buyers value this when a voice message to many numbers should be triggered by an event in another system.
How it works
From setup to everyday use
- 1
Prepare list and message
Bring in the contact numbers you want to reach and either record your message or type a script for text-to-speech. Use DNC scrubbing to remove do-not-call numbers before you continue.
- 2
Configure the campaign
Choose whether to send now or schedule the campaign, decide how unanswered calls should be retried, and set any keypad responses you want to capture.
- 3
Run the broadcast
BlastX dials the list and plays your message to each recipient who answers. Keypad responses are captured as the calls progress.
- 4
Review the results
Open the delivery reports to see which calls connected and what recipients pressed. Use that record to plan follow-up calls or refine the next campaign.
Who it is for
Where teams use it
Political Campaigns
Campaign teams often need to carry one message to a large number of voters or volunteers at short notice. BlastX combines bulk voice broadcasting with scheduled campaigns and DNC scrubbing, so outreach is planned ahead and respects recipients' do-not-call preferences.
Emergency Alerts
When something urgent happens, an organisation may need to send a voice message to many numbers quickly. Text-to-speech lets you write the alert as text, while retry logic and delivery reports help you see who has been reached.
Promotional Calls
Businesses announcing an offer or event want a consistent message delivered without tying up their sales staff. Automated voice calls with DTMF response capture let interested recipients press a key, giving the team a clear set of people to call back.
Reminders & Notifications
Appointments, payment dates and service updates are easy for customers to miss when they arrive only as text. Scheduled campaigns and API access let your systems trigger reminder calls, and delivery reports show which ones were answered.
