Why did average call duration change in Aircall?
The Aircall help pages give 4 common reasons. The first to rule out: Average call duration mixes answered inbound and outbound calls, so a change in the mix of the two can move it.
What causes it?
Average call duration mixes answered inbound and outbound calls, so a change in the mix of the two can move it.
In the Aircall help:
Average duration of all answered inbound and outbound calls, measured from the moment the call is connected until it ends.
Analytics+: Overview+ dashboard, read 2026-11-12.Call duration starts when the call connects, so greeting and menu time are not in it, unlike wait time.
In the Aircall help:
This duration does not include welcome messages or time spent in IVR
Analytics+: Overview+ dashboard, read 2026-11-12.Talk time covers only answered inbound calls, so it can differ from overall call duration.
In the Aircall help:
Average time agents spent talking on answered inbound calls.
Analytics+: Overview+ dashboard, read 2026-11-12.Outbound talk time also counts time in voicemail after the call connects, so more outbound calls reaching voicemail can change it.
In the Aircall help:
Average time spent in conversation or voicemail after the call is connected.

How do I check it myself?
Look at answered inbound and outbound calls separately, since average call duration counts both together and a shift between them can move it.
In the Aircall help:
Average duration of all answered inbound and outbound calls, measured from the moment the call is connected until it ends.
Analytics+: Overview+ dashboard, read 2026-11-12.If your team uses voicemail drop, its tag shows which calls reached a voicemail.
In the Aircall help:

How does Aircall work with Feder?
- Connect Aircall to Feder and it joins your Experience apps.
- When you connect Aircall, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Aircall, one of your Experience apps. Feder only reads. It never changes anything in Aircall.
