AI cold calling software that works your list at a steady pace
AI cold calling software dials a list of prospects and holds a real conversation with the ones who pick up. In Orbit, Dex is the cold caller: you tag the contacts you want called, and Dex works that list at a steady pace, inside the hours and limits you set. Every call is recorded and transcribed on the contact.
Meet Dex
Dex is the cold caller on Orbit's AI team, and it is deliberately unglamorous. No mass blasts, no parallel-dialing tricks. You build a list by tagging contacts in your CRM, give Dex context, and it works through the list one conversation at a time.
When someone picks up, Dex has the contact's history in front of it, so the call sounds prepared rather than random. Whether the call goes well or nowhere, it leaves a record: the recording, the transcript, and a note on what was learned, saved on the contact.
What Dex does
- Works the list you tag, at a steady pace instead of a burst.
- Dials only inside the calling hours you set.
- Stops at the daily cap, which defaults to 25 calls.
- Discloses the recorded line and answers honestly if asked whether it is an AI.
- Logs every call on the contact: recording, transcript, and what it learned.
The guardrails
Cold calling is where guardrails matter most, so here is Dex's full fence. It is off by default, and you choose who it can call, by tag. It dials only inside the hours you set, stops at the daily cap (default 25), limits retries, and will not touch anyone on your do-not-call list.
On the call, it discloses the recorded line and tells the truth if asked whether it is an AI. It calls from your own Vapi account and number, so your reputation stays in your hands. Afterward, the recording and transcript sit on the contact timeline, and any follow-up it proposes is a card you approve, edit, or dismiss.
AI cold calling vs grinding the list yourself
| Orbit | Doing it yourself | |
|---|---|---|
| Pace | Steady, capped at 25 a day by default | Ten dials, then dread wins |
| Consistency | Works the list every day it is on | Skipped when the calendar fills up |
| Records kept | Recording and transcript on every contact | Tally marks and vague memory |
| Cost | Your own Vapi minutes, billed at cost | Hours of your week, every week |
| What slips | Nothing dials outside the fences you set | Follow-up on the ones who said maybe |
Cold calling fails from inconsistency, not bad scripts. Dex shows up daily, stays inside the fences, and writes everything down.

Frequently asked questions
Is AI cold calling legal?+
Rules differ by country and state, and you are responsible for the ones where you call. Orbit builds the safety habits in: calling hours, daily caps, do-not-call lists, recorded-line disclosure, and honest AI disclosure when asked.
How many cold calls does Dex make per day?+
The default daily cap is 25. Caps, calling hours, and retry limits are settings you control; Dex never dials outside them.
Does Dex use my phone number?+
Dex calls from your own Vapi account and number, never a shared pool. Vapi bills you directly at cost, and typical solo usage is cents to a few dollars a month.
Who decides which contacts get cold called?+
You do. Dex only works contacts you have tagged into its calling list, and it checks your do-not-call list before every dial.
