Drop Call Seconds for inbound: when a queued call counts as dropped

Every inbound queue needs a limit on patience. If a caller sits on hold forever because no agent ever frees up, that is bad for them and bad for your numbers. Drop Call Seconds is the setting that draws that line. It is the number of seconds a queued caller can wait before VICIdial declares the call a drop and sends it somewhere else.

What the timer measures

For an inbound call, the clock starts the moment the customer line is picked up and the caller is sitting in the in-group queue. From there VICIdial counts up. If an agent answers before the limit, the timer never matters. If the count hits your Drop Call Seconds value first, the call is logged as a drop and handed off to whatever you have chosen as the Drop Action.

This matters because a drop is not the same as a caller hanging up on their own. A drop is the system deciding the wait went too long. Those drops show up in your reporting, and a queue with a low drop timer and not enough agents will rack up a lot of them.

Where the call goes after it drops

Drop Call Seconds only sets the timer. A separate Drop Action setting decides what happens when the timer fires. The caller can be hung up, sent to a recorded message, dropped into a voicemail box, routed to another in-group, or pushed into a phone menu. We cover those destinations in detail in our piece on Drop Exten, Drop Transfer Group, and Drop Call Menu. The point here is that the timer and the destination are two different decisions you make together.

Changing the timer by time of day

One fixed number does not always fit. Maybe you can tolerate a longer wait during your busiest hour because you would rather hold callers than turn them away, but you want a tighter limit the rest of the day. VICIdial supports this with an override container. You write one rule per line, each with a day of week, a start time, an end time, and the drop seconds to use during that window.

A line targeting Monday from 0900 to 0930 with a value of 300 would let callers wait five minutes during that half hour, even if your normal limit is much shorter. Times are in 24-hour server time, and you can use ALLDAYS to cover the whole week. If two rules overlap, the last matching line wins, so order your entries with the broad rule first and the specific exceptions after it.

Picking a sensible value

There is no single right number. A short timer keeps callers from stewing on hold but creates more drops when you are short-staffed. A long timer keeps more people in line but tests their patience. Set it against your real staffing and watch your Disposition reports for a week, then adjust. If you are also tracking how a queued call relates to your Abandonment rate, remember that a system drop and a caller-initiated Abandoned call are counted differently.
