The 3% abandonment rule explained

The FTC allows no more than a 3% Abandonment rate — measured as the share of answered outbound calls that were not transferred to a live agent within 2 seconds of the consumer's greeting. That 3% cap applies per Campaign per rolling 30-day period, not across the whole dialer.

What counts as an abandoned call

An Abandoned call happens when a consumer answers the phone and no agent connects within 2 seconds of that greeting. In a Predictive dialing setup, the dialer calls more lines than there are available agents, gambling that some will go to voicemail or ring out. When the prediction is wrong and too many people answer at once, the surplus calls become drops.

The formula is simple: drops divided by total answered calls, over a 30-day window. If a campaign answers 10,000 calls and 310 of them are not connected to an agent in time, the Drop rate is 3.1% — over the limit.

How VICIdial measures the 30-day window

VICIdial tracks drops per campaign. The 30-day period is rolling, so it is not a calendar month reset — it is a continuous window. A spike in drops on one day does not reset on the first of the next month; those drops stay in the calculation for 30 days from when they occurred.

**Gotcha:** Running multiple campaigns is not a way to average down your drop rate. Each campaign is evaluated independently. A campaign sitting at 4% is out of Safe Harbor even if another campaign in the same organization is at 1%.

Drop rate vs abandonment rate in VICIdial

In VICIdial's real-time report and whiteboard, the drop percentage shown reflects calls that hit the Drop Call Seconds threshold with no agent available. The Drop Call Seconds field controls how many seconds after answer the system waits before classifying the call as a drop. The FTC's clock starts when the consumer finishes their greeting, which typically takes about 3 seconds. Setting Drop Call Seconds to 5 gives the consumer 3 seconds to finish and the system 2 seconds to find an agent — matching the FTC's 2-second transfer requirement.

  end

Every dropped call must trigger the Safe Harbor message — a recording stating the company name, reason for calling, and a callback number. Without that message playing, the company violates a second FTC provision on top of the drop itself.

Keeping the number below 3%

• Watch the Drop rate column in the VICIdial real-time report throughout each shift. A spike in one hour can push the campaign's 30-day average over the line.
• Lower the Dial level or switch to a more conservative dialing ratio if drops climb. Predictive dialing dials ahead; backing off the ratio directly reduces the chance of surplus answered calls.
• Use adaptive dialing mode so VICIdial automatically adjusts dial level based on current agent availability and answer rates.
• Make sure AMD (answering machine detection) (answering machine detection) is tuned well. False positives that hang up on live humans count as drops even though the call never reached an agent.
