Phone calls that sound human and never miss
Latency-optimized for natural conversation. 85+ languages. The same knowledge base as your Chat Agent.
EchoCall’s AI Voice Agent is an AI phone assistant for businesses - from an intelligent AI answering service to a full AI receptionist. 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.
In short: what the AI phone assistant does and what it costs
The EchoCall AI phone assistant answers calls for your business, responds to questions from your own content and books appointments in your calendar. It starts at €75 a month for 250 voice minutes, plus applicable taxes, and setup costs €0. To try it, you get 30 voice minutes of starting credit for 14 days, no credit card required.

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.
Integrations That Fit Your Existing Stack
EchoCall’s Voice Agent does not ask you to rip out your CRM, calendar, or phone system.

How EchoCall Compares
EchoCall runs phone and chat on one shared knowledge base, with one dashboard and one bill. Running voice and chat with two different vendors means two knowledge bases to maintain and two bills to pay.

When EchoCall is not the right fit
An AI phone assistant does not pay off for everyone. In these cases we advise against it.
You need something for your personal phone
EchoCall only contracts with businesses. It is not meant as a voicemail for your private mobile.
You only get a few calls
The Starter plan costs €75 a month even if only ten calls come in. With a few calls a week, a voicemail with fixed callback times is often enough.
Almost every call needs personal advice
If callers mainly want a legal, medical or tax assessment, the agent only handles appointments and routine questions. The advice stays with your team.
The agent is supposed to decide about people on its own
EchoCall is not intended to decide on loans, insurance risks or access to public services without human review. The agent takes down such requests, and your team makes the decision.
Our AI Voice Agent runs on the same knowledge base as our chat agent, so a caller and a website visitor always get the same accurate answer, latency-optimized, in the caller’s own language.

Frequently Asked Questions
An answering machine only records a message, and a traditional answering service depends on human staffing. An AI voice agent like EchoCall holds a real conversation: it answers questions from your knowledge base, books appointments straight into your calendar, qualifies requests, and hands over to a human live when needed - around the clock.
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.
