The problem
Every missed or queued call is a customer you might lose.
Inbound lines still drop calls outside hours, stall at peaks, and burn staff time on questions your systems already know how to answer.
Long hold times when call volume peaks
Repetitive status and FAQ questions tying up staff
Customers who prefer to speak in their own language
Capabilities
Built for real conversations, not scripted menus.
Low-latency streaming voice with barge-in — callers can interrupt — plus knowledge, actions and human hand-off when it matters.
11 languages
English, Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil and Telugu — Indian-language speech recognition and natural voices.
Knowledge base (RAG)
Answers from your documents and FAQs so callers get self-service help before anything needs escalation.
Actions in your systems
Takes real actions via your systems’ APIs — proven on Tecell’s EV-charging platform for live status, session control, payments and diagnostics.
Verification before actions
Step-by-step confirmation with the caller before any action runs, so operations stay under control.
Live-agent hand-off
Transfers the call to a human with full context. Agent directory with rotation and availability.
Multi-agent routing
Conversations route to specialised agents — for example support, operations or sales — based on intent.
Guardrails
Prompt-injection and restricted-information protection, abuse and rapid-redial detection, progressive throttling, trusted/blocked numbers, duration and turn caps, analytics.
Transcripts & admin console
Call records and transcripts stored; admin console for agents, knowledge, live agents and guardrails.
Proof
Proven on our own customer line.

Caller reports a problem
A caller reports that a charger won’t start.
Identify & check live status
The agent identifies the station and checks live status via the charging platform API.
Confirm, then act
Station and connector are confirmed with the caller; the agent starts the session or guides the fix.
Transfer if needed
If the issue needs a person, the call transfers to a human with full context.
11 languages

FAQ
Questions teams ask before a voice-agent demo.
Straight answers on languages, telephony, actions, hand-off, guardrails and go-live.
What can the voice agent do?
It answers inbound phone calls in natural conversation, draws on your knowledge base, takes verified actions through your systems’ APIs, and transfers to a live agent with context when needed.
Which languages?
Eleven languages with Indian-language speech recognition and natural voices: English, Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil and Telugu.
Can it use our existing phone numbers?
Yes. Your numbers connect via SIP telephony. Exotel is verified; other SIP providers are configured per deployment.
Can it take actions in our systems?
Yes. The agent calls your systems’ APIs — proven on Tecell’s EV-charging platform for live status, session control, wallet look-ups and diagnostics — with step-by-step verification before any action.
What happens when it can’t help?
It hands the call to a human with conversation context. An agent directory supports rotation and availability so transfers reach someone who can help.
How is misuse handled?
Guardrails include prompt-injection and restricted-information protection, abuse and rapid-redial detection, progressive throttling, trusted and blocked numbers, call-duration and turn caps, plus analytics.
Cloud or on-premises?
Both. Managed cloud or fully self-hosted / on-premises (including a self-hosted media server) — the same application, with no code changes between deployment modes.
How fast can we go live?
Go-live is measured in weeks and depends on scope and integrations. A focused single-line setup on your number and FAQs is the fastest path.
