Caller IDs & spam scores

Every outbound call goes out from one of your team’s caller IDs. Carriers score those numbers, and a number carriers don’t like starts showing up as Spam Likely on handsets — or stops connecting at all. ColdDialr watches for that and pulls numbers before it gets that far.

They live under Lists → Caller IDs. Adding, pausing and assigning numbers needs the Manage caller IDs permission.

What’s on a number’s card

• The number, its area code, region and country.
• Spam score — the coloured badge, 0 to 100. Lower is better.
• Active toggle — pause a number by hand without deleting it.
• Answer rate — the share of dials the carrier recorded as answered, over the last nightly pass.
• Dials today — a live counter, the one the daily cap acts on.
• Dials (nightly) — the health check’s own total, up to 24 hours stale. It’s shown because it’s the denominator the answer rate is built from.
• List — pin the number to one list, or leave it in the general pool.
• Last used, and an Inbound section for what happens when someone calls the number back (log it, or notify the team).

The spam score

A nightly health pass looks at each number’s recent calls and builds one 0–100 score out of three signals:

Signal	What it means	Weight
Blocked rate	Calls the carrier refused outright	up to 50 points
Short-call rate	A human answered and hung up inside 10 seconds	up to 40 points
Low answer rate	Nobody picking up at all	up to 10 points

The badge colour is a warning system, not a verdict:

• Under 12 — green. Healthy.
• 12 to 22 — yellow. Worth watching.
• Over 22 — red. Heading for deactivation.

Roughly, those bands are “under 14% / 14–28% / over 28% of the humans who answered hung up within ten seconds.” Red doesn’t mean dead — it means this number is on a path, and it’s time to ease off.

Two numbers that aren’t what they sound like

Answer rate counts answering machines and voicemail, because a machine picking up still proves the carrier put the call through. It is not a human-contact rate, and it will always look higher than your connect rate.

The short-call rate ignores machines entirely. A machine answering and being hung up on is normal AMD behaviour, and counting it would make voicemail-heavy lists look like reputation problems.

When ColdDialr pulls a number

The health pass runs once a day and deactivates a number that trips any of these:

• Blocked rate above 5%
• Answer rate below 15%
• Short-call rate above 50%
• Composite score of 65 or more

There are floors on the evidence, so one bad afternoon can’t cost you a number: the rate-based checks need at least 20 calls behind them, and the short-call check needs at least 30 human answers.

A deactivated number stays on the page with its reason recorded. It’s out of rotation until someone turns it back on.

Resting, and the daily cap

No single number may take more than 150 dials a day. When one hits the cap it picks up a Resting badge and steps out of the rotation until the counter rolls over.

Resting is not a punishment and not a fault — the number is still active, and it comes back on its own. The cap exists because without one, rotation kept handing the same number the majority of a day’s calls, which is precisely how a number gets flagged.

How ColdDialr picks which number to call from

1. A number pinned to the list wins. Assigning a caller ID to a list on this page is a stronger statement than any preference below.

2. Same country as the person being called. This is a floor, never a preference — a cross-border caller ID can break the audio path, and on bridged parallel calls it produced several times the rate of dead-air complaints.

3. Then the list’s caller-ID strategy. Local presence ranks by proximity: exact area code first, then same state, then the healthiest number available. A list can also be pinned to US-only or Canada-only numbers.

4. Then health. Among what’s left, the lowest spam score and the least recently used number goes first — skipping anything resting on its daily cap.

A brand-new number has no measurements yet, so it can’t be ranked on health. Rather than letting it either dominate the pool or never get used, it’s given a warm-up quota — about one call every fifteen minutes — until it has earned a real score.

Keeping numbers healthy

• Watch the yellow, not the red. By the time a number is red you’ve already spent most of its goodwill.
• Go easy on Parallel. It’s the hardest mode on reputation, which is why lists stop offering it after a few sessions. See Dial modes.
• Spread the load. More active numbers in the pool means fewer dials each, and the daily cap does the rest.
• A red number isn’t rescued by resting it a day. The score is built from recent traffic; the fix is fewer aggressive sessions against it, not a pause.
