What is an AI voice agent?
An AI voice agent is software that holds spoken conversations over phone calls to answer common questions, qualify leads, confirm appointments and update records. Stack18 builds voice agents that connect to your CRM, support desk and telephony, escalate to a person when needed and log every call.

AI Voice Agent questions.
Which languages are supported?
We start with Hindi and English, which most of our clients need. Regional languages are assessed during discovery against quality and cost.
Will callers know it is an AI?
We recommend telling callers they are speaking with an automated assistant, and we design the opening script and compliance rules with you.
What if the agent cannot answer?
It hands the call to a person with a summary of the conversation so far, or books a call-back, rather than guessing.
Are there calling regulations to follow?
Yes. Outbound calling in India has consent and do-not-disturb rules. We build in consent checks and confirm requirements with your legal advisor.
Can we pilot it on one use case?
Yes. A common start is after-hours inbound or lead qualification, measured against your current call-back time.
