Abandoned call
An abandoned call is an inbound call where the caller hangs up while waiting in the queue, before any agent answers.
An abandoned call is an inbound call where the caller hangs up while waiting, before any agent answers. They reached your virtual queue, heard the welcome message and maybe some music on hold, then gave up. Every abandoned call is a customer you lost contact with, so the count is watched closely on inbound teams. A rising abandon count is often the first sign that your queue is outpacing your staffing.
Note that the inbound meaning differs from the outbound one. In dialing, an abandon usually means the dialer connected a live person but had no agent to give them, which the regulators care about under tcpa. Inbound abandons are caller-initiated hang-ups while waiting. Both feed an abandonment rate, but they describe very different events, so be sure which one a report is counting before you read too much into the number.
Reducing them
The simplest fix is shorter waits, which usually means more agents during peak hours. When you cannot add staff, announcing an estimated hold time and a place in line keeps people on the line longer, and offering an in queue callback turns a would-be abandon into a kept appointment. Each abandon also pulls down your service level, so cutting them helps two numbers at once and makes the queue feel calmer for everyone still waiting.
It helps to set a "short abandon" threshold, often a few seconds, so callers who hang up almost immediately are not counted the same as those who waited a minute. Without it, accidental dials and quick hang-ups make your abandon numbers look worse than the real caller experience. Decide on that threshold once, document it, and apply it consistently across your reports so the trend line means something. Changing it midway makes a quiet week look like an improvement when nothing actually changed, so pick a number and stick with it.

Abandonment rate
The percentage of answered outbound calls that ended without the caller reaching a live agent — closely tied to, and often used alongside, drop rate.
Estimated hold time
Estimated hold time is the system's guess of how long a waiting caller will sit in the queue before reaching an agent, often announced to the caller.
In-queue callback
An in-queue callback lets a waiting caller hang up but keep their spot, so an agent calls them back when their turn arrives instead of holding.
Place in line
Place in line is a caller's numbered position in the waiting queue, often announced so they know how many callers are ahead of them.
Service level
Service level is the percentage of inbound calls answered within a target time, such as 80 percent answered within 20 seconds.
Virtual queue
A virtual queue holds inbound callers who are waiting for an agent, ordering them and tracking their wait while they listen to messages or hold music.
