How it works
There’s no separate test environment and no reserved test phone numbers that skip actually dialing. An originate call, once it reaches a connected carrier, is a real phone call.When to use it
Most API development doesn’t touch origination at all — building and testing against campaigns, CDRs, and webhooks doesn’t place a single call. Where you do need to exercise real dialing, do it deliberately:- Use a workspace or campaign set up specifically for testing, not a production one.
- Dial numbers you control — your own mobile number, a colleague’s extension — never a real customer or lead number.
- Keep test campaigns paused except when you’re actively testing, so nothing dials unattended.
