Omnichannel Communication

Overview

Voice broadcasting, also known as outbound dialing or OBD, lets you deliver a pre-recorded voice message to a large contact list automatically. Office24by7 dials your entire audience in parallel and plays your message the moment they answer — ideal for alerts, reminders, promotions, notifications and awareness campaigns that need to reach thousands of people quickly and personally in their own language.

It is more than one-way announcements. Add press-key options so listeners can confirm attendance, opt in, request a callback or connect to an agent — turning a broadcast into an interactive campaign. Every call is tracked for answered, unanswered and keypress outcomes, campaigns respect DNC and DPDP suppression lists, and results flow back into the CRM so you can measure reach and follow up with anyone who responded.

Payment alerts

A finance company sends automated voice reminders for due EMIs in the customer's language, with a press-key option to reach the collections team directly.

Awareness campaigns

Interactive, not one-way

Press-key responses turn a broadcast into a two-way campaign that captures intent and callbacks.

Built for compliance

DNC, opt-out and DPDP suppression lists are checked before every campaign, in line with TRAI rules for commercial calls.

Measurable outcomes

Answered, unanswered and keypress data show real reach and feed responders back for follow-up.

FAQ

Questions, answered

Because voice broadcasting dials contacts in parallel rather than one at a time, you can reach thousands of people within minutes, depending on your channel capacity and carrier concurrency.

Yes. You can add press-key options so recipients confirm attendance, opt in, request a callback or connect to a live agent, and every keypress is tracked and can trigger follow-up in the CRM.

Your contact list is automatically checked against do-not-call and suppression registries before dialing, and opted-out numbers are excluded, helping your campaigns stay compliant with DNC and DPDP rules.

You can schedule campaigns for the ideal hours and stagger sends by list, language or region, so messages land when recipients are most likely to answer.

You can configure retry rules to re-attempt busy or unanswered numbers a set number of times, and all outcomes — answered, unanswered, busy and keypresses — are reported for the campaign.
