Pick-up by hour of the day, IST, from the pre-sales calls in our audit: 14:00 had 35%, 15:00 had 21%, 17:00 had 26%, 18:00 had 27%, 19:00 had 18% and 20:00 had 29%.
The mistake
1,363 calls, about half of all calls, went out in the 18:00 hour. Crowding one hour also pushed us over the voice provider's concurrency limit, which billed a burst rate.
What we do now
Calls are spread across the hours people answer, with about ten conversations running at once, and never crowded into a single hour.
