Quick answer: A press-1 voice campaign is an automated call that plays a recorded message and asks the listener to press a key on their phone, for example "press 1 to confirm". The platform records which key was pressed against each number. Your team can then follow up with the people who responded. It works on any phone that can receive a call, including basic handsets.
Plain broadcast calls tell people something. Press-1 calls let them answer back. That small difference turns a one-way announcement into a way to collect confirmations, interest and feedback at scale. This guide explains how it works in practice. For the wider picture, start with our guide to bulk voice call service in India.
What happens on a press-1 call
- The platform dials a number from your uploaded list.
- When the person answers, the recorded or text-to-speech message plays.
- The message asks for a keypress, such as "press 1 if you are interested".
- The phone sends the key tone back as a keypad signal, usually called DTMF.
- The platform logs the number, whether the call was answered, how long it lasted and which key was pressed.
The listener needs nothing but a phone. There is no app to install and no internet connection involved, which is why the format suits audiences that do not use smartphones or data much.
Where press-1 campaigns fit
- Confirmations. Appointment, delivery or event reminders where you want a yes.
- Interest capture. A property launch or admission drive where "press 1 if you want a call back" gives your team a shortlist.
- Quick feedback. A one-question survey with answers on keys 1 to 5.
- Opt-in or opt-out. Letting people say whether they want future calls.
Our article on bulk voice call use cases across industries shows where each of these tends to appear.
Designing the keypad question
Ask one question
One question with one or two options is the sweet spot on an outbound call. The listener did not ask to be called, so every extra option costs you responses.
Say the option after the reason
Give the reason first, then the key. "Your policy renews on the 20th. To get a call from our team, press 1." If the key comes first, the listener has not yet heard what they are pressing for.
Keep the keys predictable
Use 1 for yes and 2 for no, and keep that pattern across campaigns. Do not use keys like star or hash for outbound questions.
Write the script for the ear
The same rules apply as for any voice message. Our guide to writing a bulk voice call script covers the wording.
What to do with the responses
A keypress is only useful if someone acts on it. Before launch, decide who will see the list of responders, how soon they will call back, and what they will say. A person who pressed 1 and heard nothing for three days will remember it. For a long list of responders, the people who pressed a key are your warm leads, and a CRM keeps them from getting lost.
The responses and call logs appear in the campaign report, including answered calls, call duration and key-press inputs. See our guide to voice campaign reports for how to read them.
Where the Nexcomm service fits
Nexcomm's bulk voice call service supports press-1 campaigns, scheduling, retries for unanswered numbers, and call logs that include keypress inputs. If you need a menu with several levels rather than a single question, that is a different tool: an IVR. Our guide to IVR menu design explains the difference.
Common mistakes
- Too many options. Three or more choices on an outbound call, and people stop listening.
- No follow-up plan. Responses collected, nobody called back.
- Asking for sensitive information by keypad. Do not ask people to key in card or account numbers on a promotional call.
- Calling without consent. A keypad option does not change the rules on who you may call. See our summary of TRAI rules for bulk voice calls.
Frequently asked questions
What does DTMF mean?
Dual-tone multi-frequency. It is the tone a phone sends when a key is pressed. The platform listens for it during the call.
Does the listener need a smartphone?
No. Any phone that can receive a call and press keys during it will work.
How many options should a press-1 call offer?
One or two. If you need more, use an IVR instead, where the caller chooses their own route.
What happens if the person does not press anything?
The call is logged as answered with no key pressed. Decide in advance whether to treat that as no interest or to retry on another day.
Can a press-1 campaign be used for political outreach?
Voice is an allowed channel for election outreach, but the Election Commission's rules and TRAI's rules both apply. Our rural voter voice guide covers this.
