Voice & phone numbers

Give your agent a phone number and it can place and answer calls — using your own telephony and your own voice keys, so there's no per-minute platform markup.

Connect a number

Under Phone Numbers, connect a number from Plivo, Exotel, Twilio, or your own SIP trunk. Bring your own provider account (BYOK) and paste the keys once.

🇮🇳 In India, incoming calls are ₹0/min — inbound is already wired for Exotel, Plivo, Twilio and SIP.

Assign an agent & go live

  1. Create a voice agent (or install a voice template) and set its voice, language and persona.
  2. Assign the agent to your number and choose inbound, outbound, or both.
  3. For outbound, launch a campaign to call a contact list.

Voices & voice cloning

Pick India-native voices from Sarvam or Smallest.ai, or use OpenAI / ElevenLabs. Manage and clone voices in the Voice Library. The agent can auto-detect the caller's language and switch to it mid-call, and hand off to a human number when asked.

✅ Every call is transcribed and can trigger post-call actions: an AI summary, a WhatsApp follow-up, a CRM lead, or a team notification.

Call behaviour — noise, interruptions & acknowledgement

Each agent has a Call behaviour section so it stays natural on real-world lines:

  • Background noise handling — Quiet, Normal or Noisy. Pick Noisy for a shop counter, street or factory floor so background sound doesn't make the agent stop or talk over the caller.
  • Let the caller interrupt — on by default; turn it off on very noisy lines so noise can't cut the agent off mid-sentence.
  • Acknowledgement style — how the agent reacts before answering: a natural short word (“sure”, “haan”), a full phrase, none, or your own custom line.
  • Advanced — fine-tune raw mic sensitivity and the silence-before-reply timing, or reset to the preset.
🎧 Customer on a noisy line? Set Noisy and turn interruptions off — the agent then ignores background sound and finishes what it's saying.

Frequently asked questions

Can the AI make and receive phone calls?
Yes. Connect a number from Plivo, Exotel, Twilio or your own SIP trunk, assign a voice agent, and it can handle inbound, outbound, or both.
Are there per-minute charges from Convo360?
No. You use your own telephony account (BYOK), so you pay your provider directly. In India, incoming calls are ₹0/min.
Which voices and languages are supported?
India-native voices via Sarvam and Smallest.ai, plus OpenAI and ElevenLabs. Agents can auto-detect the caller's language and switch to it mid-call.
The agent stops answering when there's background noise — how do I fix it?
Open the agent's Call behaviour section and set Background noise handling to Noisy, then turn off "Let the caller interrupt". The agent then ignores background sound instead of treating it as the caller speaking, so it doesn't stop mid-sentence. You can also fine-tune raw mic sensitivity under Advanced.
Can I change how the agent acknowledges the caller?
Yes. Each agent's Acknowledgement style can be a natural short word (like "sure" or "haan"), a full phrase, none at all, or a custom line you write.
