Voice Calling Service for Business
What is a business voice calling service?
A business voice calling service lets a company place automated calls to customers, run IVR menus that respond to keypad input, and turn missed calls into leads, through an API or a campaign panel. Teleopedia's voice tools cover outbound dialer (OBD) campaigns, IVR workflows, voice OTP and missed-call numbers, on the same panel as bulk SMS, WhatsApp and RCS.

IVR API
Menus, call routing and keypad (DTMF) input for automated voice workflows, with SMS and WhatsApp follow-ups.

IVR pricing in India
What goes into the cost of an IVR setup: call charges, platform fees, flow complexity and volume.
When a call works better than a message
- Urgent reminders: a payment due today or an appointment tomorrow is harder to ignore as a call than as a text.
- OTP fallback: if an SMS code is not delivered or read, an automated call can read it out. See Voice OTP.
- Customers who prefer calls: some people do not read long messages, or are more comfortable listening, including in their own language.
- Lead capture: a missed-call number costs the caller nothing, so it lowers the barrier to enquire or opt in.
Most teams combine voice with other channels, for example WhatsApp first, SMS next and a call last. See omnichannel fallback routing for how that order is set.
Rules to plan for in India
Voice campaigns in India are subject to TRAI's rules, including customers' DND preferences and permitted calling hours. Read DND compliance in India and DLT registration before you launch a campaign, and confirm with your account team which registrations apply to your use case. Primary source: TRAI.
Voice calling questions
What is an OBD call?
OBD stands for outbound dialer. It places automated calls to a list of numbers, plays a recorded or text-to-speech message, and can collect keypad input. Teleopedia returns call status for every call.
Can voice be used as a fallback for SMS or WhatsApp?
Yes. You can set an order such as WhatsApp, then SMS, then an automated call, and stop as soon as one channel delivers.
Do voice campaigns need DLT registration?
Voice campaigns in India follow TRAI's rules, including DND and calling hours. Your account team will confirm which registrations apply to your use case before you start.
How is voice calling priced?
Cost depends on call volume, call length and the complexity of the flow, not on a fixed per-seat fee. See IVR pricing in India for the factors, or talk to the team for a quote.
