WHY VOICE AI ON REPLYAGENT
Three reasons it beats a DIY voice stack.
Telephony, AI orchestration, transcription, recording, MCP connectors, CRM. The voice stack you would otherwise glue together over six weeks, pre-wired into one platform.
Realtime by default
Sub-second response latency on every call. Interruptions, pauses, and topic shifts handled the way humans handle them. No awkward gaps, no robotic delay.
AI Studio inside every agent
Voice agents share the same brain as your chat assistants. One knowledge base, one prompt, one prompt-chain, one fallback policy. Talk or type, same intelligence.
MCP-native by design
Plug Cal.com, Supabase, Baserow, or any MCP server into a voice agent. Book meetings, query live records, write structured data, mid-call, without code.
BRING YOUR OWN TWILIO
Your number. Your carrier. Zero middleman.
Voice on ReplyAgent runs on Twilio Elastic SIP Trunking, the same infrastructure trusted by the world's largest brands. Connect your own Twilio account in one click. You pay Twilio at their published carrier rate, we add nothing on top of minutes.

RealtimeOne platform. No middleman. Realtime voice AI from end to end.
AI STUDIO ON VOICE
A real AI brain on the phone line.
Connect any AI Studio assistant to a Twilio number. Pick the realtime model (OpenAI Realtime or Gemini Realtime), point it at your knowledge base, and inbound calls get answered in your brand voice with full conversation context. Auto-fallback if the primary model degrades, mid-call.
- OpenAI Realtime + Google Gemini Realtime, switch per agent
- Train on your website, PDFs, plain text, or live database
- Auto-fallback with full call context preserved end-to-end
- Multi-agent orchestration: triage, handoff, escalate
MCP SERVERS ON VOICE
Connect any tool mid-conversation.
Voice agents speak MCP (Model Context Protocol) natively. Plug in Cal.com to book meetings live, Supabase or Baserow to query and write records, or any other MCP server you connect. The caller asks for an appointment, the AI checks your calendar, books it, and confirms, before they hang up.
- Native MCP: Cal.com, Supabase, Baserow, and more
- Book meetings, query databases, update records live on the call
- Add custom MCP servers, no platform-side code changes
- Same MCP layer as your chat AI Studio assistants
AUTOMATIC TRANSCRIPTION
Every call. Transcribed and searchable.
Every voice conversation is transcribed in real time, with speaker labels and timestamps, and saved against the contact. Search across hundreds of calls by keyword, intent, sentiment, or any custom field. Export anywhere. Trigger Smart Flows on any phrase.
- Realtime transcription with speaker labels and timestamps
- Full-text search across the entire call archive
- Sentiment, intent, and topic tagging per call
- Trigger Smart Flows on keywords, escalation signals, or outcomes
CALL RECORDINGS
Every minute, on record.
Inbound and outbound calls are recorded automatically and stored against the contact in the CRM. Replay any call, share it with your team, audit the AI's behavior, train new agents, or close compliance loops. Encrypted storage. Retention policies you control.
- Inbound + outbound recordings, stored against the CRM contact
- One-click playback inside the conversation timeline
- Configurable retention and per-workspace data residency
- Compliance-ready audit trail, exportable on demand
AI CALL TRANSFERS
Describe when to transfer. The AI does the rest.
Write the rule in plain English, pick the destination agent, save. The voice AI listens for that signal on every call, a frustrated customer, a billing question, an explicit request, and forwards the line to the human you chose. No code, no IVR menu, no missed escalations.
- Define transfer rules in plain language, the AI matches them live
- Pick a specific destination agent per rule
- Auto-escalate on frustration, intent, or any keyword you describe
- Powered by Twilio call forwarding, carrier-grade reliability
BULK CALLING AT SCALE
100 concurrent calls. One campaign.
Launch outbound voice campaigns with hundreds of AI agents working in parallel. Cart recovery, COD confirmation, lead qualification, re-engagement, appointment reminders. Per-call delivery status, recording, and transcript fed straight into the CRM and your downstream automations.
- Up to 100 concurrent AI calls per campaign out of the box
- Per-contact dial-out scheduling with retry logic
- Live campaign dashboard: dials, connects, durations, outcomes
- Outcomes auto-tagged on the CRM contact and pipeline stage
WORKFLOW INTEGRATIONS
Trigger workflows on any voice event.
Every voice event, call placed, call answered, call ended, transcript ready, keyword matched, can fire a Smart Flow, an n8n workflow, a Make.com scenario, or any external webhook. Branch on what was said, who said it, and what the AI inferred.
- Smart Flows triggered by voice events or keywords
- Native connectors for n8n, Make.com, and webhooks
- Branch on transcript content, sentiment, or AI output
- Update CRM, hit APIs, schedule follow-ups, all hands-free
