Who moves, and why

We did not go by job title. Every line below was scored on its own call records over six months: how many calls it makes, how long they last, how often it dials a number it has never dialled before, and how much comes back the other way. Cold calling has a shape, and it shows up clearly.

lines move to a metered plan

lines stay on their unlimited plan

lines barely used - no impact either way

How we decided

A line is marked as a cold caller if it hits three or more of these four:

200 or more outbound calls a month. Volume is the first thing any carrier looks at.
60% or more of the numbers dialled were dialled once and never again. That is working through a list, not managing relationships.
Average answered call of 50 seconds or less. Short conversations mean pitches, not business.
More than 15% of answered calls under 6 seconds, or an answer rate below 80%. These are the two markers the industry scam-call code names directly.

Lines with fewer than 50 calls in six months are set aside. They cannot move any measurement either way.

Calls per month is the average across the months each line was actually active. Dialled once is the share of destination numbers that appear exactly one time in six months.

The thirteen that stay

These lines are not doing cold outreach, so moving them to a metered plan would cost us money and fix nothing. Two deserve a note.

Jennelyn must not move. She dials New Zealand almost exclusively - about 515 minutes a month. New Zealand mobile is free on Unlimited Australia Plus, because that plan includes 50-plus countries. Every metered plan charges it as international, billed in whole minutes. Moving her would create a bill of roughly $100 a month that does not exist today. She is not a cold caller. Leave her alone.

Health Reach is client reception work. The two Health Reach lines take 1,314 inbound calls over six months and average 69 and 102 seconds. That is a switchboard, not outreach. However, three people share those two numbers, which is its own Fair Use problem - see Gaps and checks.
