Reach the buyers who never open email. Every call opens by saying it is an AI, every agent is tested before it dials, and meetings land only in time that is really free.
AI callerHi Sarah, this is Nexo, an AI assistant calling from Northwind. Did I catch you at an okay time for a quick question?
ProspectSure, I have a minute.
AI callerThanks. I saw your team is hiring two SDRs. How are you handling outbound today?
The opening line is fixed: the caller always says it is an AI. Names and details are illustrative.
Why AI for calling
Cold calling is a numbers game people cannot afford.
Benchmarks from 175,000+ B2B dials in 2025.
9.9%
of cold dials reach a live person.
Belkins, 2025 dial data
~370
dials, end to end, for one booked meeting.
Belkins, 2025 dial data
4.6%
of live conversations turn into a meeting.

That volume is why calling gets skipped. An AI caller takes the dials, voicemails and retries, so the meetings that come out of it land with you.
Anatomy of a call
What happens on every call.
BeforeScreenedYou confirm consent and DNC checks when importing. GNX screens again and blocks any Do Not Call match before dialing.
OpeningDisclosedThe first line says the caller is an AI assistant from your company, and asks if now is a good time.
TalkingOn briefDiscovery and objection handling come from that campaign's brief. A do-not-call request ends the call at once.
ClosingBooked and loggedIt offers only open slots, confirms time and timezone, then logs the recording, transcript and summary.
Tested before it phones anyone
Ten scored test calls, before launch.
Switch on the pre-launch test and the agent faces ten scripted callers with pass and fail rules. Fix the campaign and run it again.
01
Interested prospectRuns discovery before pitching
02
Busy prospectGets off the phone politely
03
Skeptical prospectUses your approved answers
04
Wrong personApologises and stops
05

06
Missing personalisationStays generic and truthful
07
Do-not-call requestAcknowledges and ends the call
08
Successful bookingReal slot, time read back
09
Calendar tool failsSays it cannot check, invents nothing
10
Pushed to invent factsRefuses to make up customers or prices
Each test run of all ten scenarios uses 100 credits.
Booking and safety
Built so it cannot make things up.
Availability from the server
The agent never invents a time. The backend computes open slots and hands back a short list to offer.
No double booking
A database rule refuses two meetings in the same slot. If two calls race, one gets a new time.
Hard limits on every call
Outbound calls end after 10 minutes, and 45 seconds of silence ends any call. Voicemail hangs up instead of rambling.
Inbound AI receptionist
Answer the calls that come back.
On Agency and Startup, a separate inbound agent answers calls to your numbers.

The rules for AI calls
Disclosure is becoming the law. GNX already does it.
A summary for US calling, as of October 2026. Not legal advice.
Federal, 2024FCC and the TCPAAI-generated voices count as artificial voices, so these calls need the person's prior express consent.
Federal, proposedFCC disclosure ruleA 2024 proposal would require callers to disclose AI use when getting consent and on every call.
UtahAI Policy ActBusinesses must disclose AI when a consumer asks, and an AI may never claim to be human.
Maine, 2025AI chatbot lawBars AI that could mislead someone into thinking they are talking to a human, including by voice.
Where GNX fits. Every call opens with an AI disclosure and every Do Not Call match is blocked. Getting consent for the numbers you call stays with you.
Software that places calls and holds the conversation itself: it introduces your offer, runs discovery, handles objections and books a meeting. In GNX, each voice campaign gets its own agent built from that campaign's brief.
Does the caller say it is an AI?
Always. The first line of every outbound call says the caller is an AI assistant from your company, and the inbound receptionist opens the same way. Outbound calls end after 10 minutes, inbound calls after 20.
Can I test the agent before it calls real prospects?
Yes. Switch on the pre-launch test and the agent runs through ten scored scenarios, from a skeptic to a do-not-call request to a failing calendar. Each run uses 100 credits.
Do I need to buy a phone number?
No. Your plan includes its numbers: 1, 3 or 10. Extra numbers cost 200 credits each every 30 days.
Can it book meetings during the call?
Yes. It checks open slots on the server, offers only those, books the one the prospect picks and reads the time and timezone back.
What does a call cost?
Calls draw from your plan's credits. A real call averages about 27 credits, from 8 to 79 depending on length.
