Real situations
When teams bring us in on Retell AI
Callers wait for the agent to answer
There is a noticeable gap before each reply and some callers hang up.
What we doWe tune responsiveness and test the timing on real calls.
Callers cannot get a word in
The agent keeps talking when a caller tries to correct it.
What we doWe adjust how easily callers can interrupt, then check it with recordings.
Nobody knows how the calls went
Calls are handled, but outcomes are never reviewed or reported.
What we doWe set up call review and reporting so you see what the agent achieves.

Questions
Retell AI management — common questions
How many concurrent calls does Retell AI include?
Every account includes 20 concurrent calls. Additional concurrency costs $8 per concurrent call per month.
What does responsiveness do in Retell AI?
It controls how quickly the agent responds. Lowering it by 0.1 adds about half a second of wait, which helps with callers who pause between thoughts.
What is interruption sensitivity in Retell AI?
A value from 0 to 1 that controls how easily a caller can interrupt the agent.
Can Retell AI handle short spikes above our concurrency?
Retell documents a burst option that allows extra concurrent calls — up to the lower of three times your limit or 300 more — billed per minute.
How much does Retell AI management cost?
From $100 a month. The exact price depends on users, volume and what needs setting up, and you get it in writing within 2 working days, without giving us access.
Is there a minimum term?
