Phone calls that sound human and never miss
Latency-optimized for natural conversation. 85+ languages. The same knowledge base as your Chat Agent.
Every missed call is a missed customer. EchoCall’s AI Voice Agent answers inbound calls, places outbound calls, and handles both directions of a conversation with natural, latency-optimized speech in real time.
Built for real-time conversation
A single end-to-end latency-optimized pipeline instead of a multi-hop speech-to-text-to-speech detour.
including German dialects
Bavarian, Swabian, Berlinerisch and more, at native-grade quality.
for local phone numbers
Establish a local presence wherever your customers are.
Why Latency Is the Metric That Actually Matters
Most competing voice AI platforms advertise "fast" responses without publishing real numbers, because their architecture routes audio through several hops: speech-to-text, a general-purpose language model, then text-to-speech, each adding noticeable round-trip delay. Callers notice this instantly.
EchoCall is engineered to minimize round-trip delay across the full pipeline. The goal: the natural pause a human takes before answering a question and the pause our system takes should be indistinguishable.
What's Included
Everything you need to put a reliable voice agent in front of every phone call, without replacing your existing telephony stack or hiring a single additional receptionist.
- Batch outbound / mass-dialer
Run structured outbound campaigns at scale: appointment reminders, payment follow-ups, satisfaction surveys.
- SIP / bring-your-own-carrier
Works with Twilio, Telnyx, Vonage, or Sinch, so you keep your existing numbers.
- Live human handover
Escalate seamlessly mid-call, complete with a summary of what has already been discussed.
- Shared knowledge base with Chat Agent
One RAG source of truth across every channel, so answers never contradict each other.
How It Works
From signup to a live phone number in roughly five minutes.
Connect a number
Port an existing business line via SIP, or provision a new number in 60+ countries directly inside EchoHub.
Train the knowledge base
Upload FAQs, pricing, and booking rules, or point EchoCall at your website. The same base your Chat Agent uses.
Set escalation rules
Decide which topics should trigger an immediate handover to a human.
Go live
Calls start flowing through EchoHub’s real-time dashboard, every conversation logged and searchable.
Built for Every Industry
A dental practice, a real estate agency, and a logistics call center have very different call patterns, but all three lose money every time a phone rings unanswered.

How EchoCall Compares
Most AI voice platforms on the market, including ElevenLabs Conversational AI, Vapi, Retell, and Parloa, are voice-only - if you also need chat coverage, you’re integrating a second vendor, a second knowledge base, and a second bill.

Frequently Asked Questions
Most customers use it to handle the volume a receptionist can’t cover alone: after-hours calls, simultaneous calls, and routine requests, while keeping a human in the loop for anything that needs judgment.
Yes. EchoCall’s 85+ supported languages include native-grade handling of regional German dialects, not just standardized Hochdeutsch.
The agent is configured to say so honestly rather than guess, and can route the caller to a human or take a message, based on the escalation rules you define.
Initial setup typically takes about 5 minutes for a basic configuration; most customers spend additional time refining the knowledge base over the following days.
