Are you inside the 3% abandonment limit?
Open more lines than a rep can answer and some of the people who pick up get nobody. Both the FTC and the FCC cap that at 3% of calls answered by a person. Put in your line count and your answer rate — the rest is arithmetic.
Assumptions
A call is abandoned only if a second person answers between the first answer and the rep being bridged — everything else is hung up while it is still ringing. So the window matters as much as the line count, and both are yours to set.
Answer rate is the share of dials a person picks up, not the share that turns into a conversation. Published B2B benchmarks sit around 8–12% on generic data and 18–22% on verified mobile — the sources are on the parallel dialing guide.
1.1%
of calls answered by a person, against a 3% limit
Anything past 3% is outside the safe harbour. The scale runs to 10%.
Which rule applies to you, and why
Two regulators cap abandoned calls at the same 3%, and they do not have the same scope. Most pages on this subject cite one of them and imply it is the whole picture.
| FTC — Telemarketing Sales Rule | FCC — TCPA rules | |
|---|---|---|
| Where the 3% lives | 16 CFR 310.4(b)(4) | 47 CFR 64.1200(a)(7) |
| What it is measured against | Calls answered by a person | Calls answered live by a person |
| Over what period | A single campaign under 30 days, or each successive 30 days | A 30-day period, per calling campaign |
| When a call counts as abandoned | Not connected to a representative within two seconds of the completed greeting | Same two-second test |
| Business-to-business calls | Exempt — 16 CFR 310.6(b)(7) | No exemption in the subsection |
The practical answer for a B2B team. The FTC's rule exempts calls between a telemarketer and a business under 310.6(b)(7), keeping only the deceptive-practice provisions at 310.3(a)(2) and (4) and a carve-out for retail sales of nondurable office or cleaning supplies. The FCC's rule contains no such exemption and reaches telemarketing calls generally. So the 3% still applies to you — through the FCC rather than the FTC. That distinction changes who enforces it and under which authority, and it does not change the number you have to hit.
Why the window matters as much as the line count. A dialer hangs up the lines that are still ringing the moment someone answers, so most surplus calls are never answered by anyone and cannot be abandoned. A call is only abandoned if a second person picks up between that first answer and the rep being connected. That makes the abandonment rate directly proportional to how long your dialer takes to bridge — halve the delay and you halve the rate, at the same line count and the same answer rate. It is the one lever on this page that costs nothing in dials.
What the safe harbour asks for besides the 3%. 16 CFR 310.4(b)(4) is a four-part test, not a single threshold: ring for at least 15 seconds or four rings before disconnecting; play a recorded message identifying the seller within two seconds of the greeting on any call you do abandon; and keep records showing you did. The recorded message does not make an abandoned call un-abandoned — the rule requires it of abandoned calls — so it changes your exposure, not the figure above.
This is not legal advice. It is arithmetic against two published rules, with the subsections named so you can check both. State law adds requirements this does not model, calling mobile numbers raises consent questions under the TCPA that have nothing to do with abandonment, and none of it substitutes for your own counsel.

Common questions
How is the abandonment rate calculated?
Against calls answered by a person, not against dials. With L lines open for one rep and an answer rate of a, the expected answers per burst are L × a and exactly one of them reaches the rep, so the rate is 1 − (1 − (1−a)^L) / (L × a). Measuring against dials instead is a common and self-flattering error: on a list with a 10% answer rate, 3% of answered calls is a far smaller number than 3% of dials.
Does the 3% limit apply to business-to-business calls?
Yes, but through the FCC rather than the FTC. The FTC’s Telemarketing Sales Rule exempts calls between a telemarketer and a business at 16 CFR 310.6(b)(7), keeping only the deceptive-practice provisions and a carve-out for retail sales of nondurable office or cleaning supplies. The FCC’s rule at 47 CFR 64.1200(a)(7) contains no business-to-business exemption and applies to telemarketing calls generally.
Why does the line count matter so much?
Because a rep can only take one call. Every additional line raises the chance that two people answer within the same moment, and the second one has nobody to hand it to. But the line count is only half of it: the other half is how long your dialer takes to connect the rep, because a surplus call that arrives after the rep is already talking gets hung up while still ringing rather than abandoned.
Does this apply to a predictive dialer?
No, and the number would be wrong if you used it that way. A predictive dialer opens lines for a pool of reps, so a surplus answer can go to whoever is free. This models a parallel dialer, where the lines belong to one rep and there is nobody to pass a surplus to. The difference between the two is set out in our guide to parallel versus predictive dialing.
Can I dial four lines and still be compliant?
On this arithmetic, usually yes — but it depends on your bridge delay far more than on the four. Set the bridge slider to your own dialer’s figure and read the answer: a dialer that opens audio in a fraction of a second abandons a fraction of what one that waits several seconds for answering-machine detection does, at the identical line count. If a vendor will not tell you their bridge time, that is the number to ask for.
Does playing a recorded message fix it?
No. 16 CFR 310.4(b)(4)(iii) requires that message of an abandoned call — it is a condition of the safe harbour, not a way out of the count. A call that gets the message is still an abandoned call for the purposes of the 3%.
