What are Short Duration Outbound Calls?
Short Duration Calls (SDCs) are outbound calls that are 6 seconds or less in duration. We allow 15% of your traffic to be SDCs on our platform. If your Short Duration call traffic goes above 15% you'll receive an email and can be penalised for this traffic with additional charges.
Short duration calls are calculate based on:
Count of short duration calls connected / Total count of connected calls (which includes the short duration call count). The time-frame will always be based in UTC from 00:00:00.
Start Date = 23rd January 2023 00:00:00
End Date = 30th January 2023 00:00:00
Short Duration Call Count = 200
Total Connected Call Count = 1000
200 / 1000 = 20% of calls considered short duration.
