Buying numbers
Your caller-ID numbers are what rotation spreads calls across. The more numbers, the lighter each one's daily load — and the healthier they stay.
How many numbers do I need?
Rotation keeps each number well under its daily cap, but it can only spread across the numbers you own. A quick rule:
| Daily calls (account) | Suggested numbers |
|---|---|
| Up to 180 | 1–2 |
| ~360 | 3 |
| ~600 | 4–5 |
| 1,000 (full ramp) | 6+ |
Aim to keep each number under ~200 calls/day — that's the Monitor's soft-warning line. Divide your expected daily volume by ~180 and add one for headroom.
Adding numbers
- Buy numbers from your account — they're added to your rotation pool automatically and start healthy.
- New numbers join rotation right away and share the load evenly with the rest.
- useasan dials on a carrier matched to your number; rotation only ever spreads across numbers of that same carrier.
Frequently asked
Can I dial everything from one number?+
You can, but it'll hit its daily cap fast and is far more likely to get flagged. Spreading across several numbers is what keeps them healthy.
Do new numbers need their own warm-up?+
Your account-level warm-up governs total daily volume; rotation keeps each number's share modest. A dedicated per-number ramp is on the roadmap.
