In education the person who answers is usually a parent, not the student. Language coverage is not a feature line on a comparison sheet here. It is the difference between a call that converts and a call that wastes a lead.
An enquiry from a tier-two or tier-three town is often answered by a parent perfectly comfortable reading an English WhatsApp message and not at all comfortable holding a ten-minute conversation about fee structures in it. This is where a lot of education calling deployments quietly fail: the agent speaks English, the parent switches to Marathi or Telugu, and the conversation ends politely with nothing captured.
Troika supports English, Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada, Malayalam, Bengali and Punjabi, plus the mixed Hinglish register most Indian families actually speak on the phone.
Worth testing before you sign: ask any vendor for a recorded call in the specific language your enquiries arrive in, not a demo in Hindi. A platform that lists twenty-four languages and performs well in two is common, and you will only find out in the first week of admission season.
