Wait
The Wait scenario block will pause scenario execution for a specified number of seconds.
Settings
The Wait duration setting is where you specify the number of seconds for which any scenario execution should be paused. Decimal fractions are allowed. In the scenario shown, the wait duration is set for 2 seconds, which gives the system 2 seconds to wait before answering the call.
Note: Regarding the use of decimals, there is a known issue that rounds the wait time up to the next second. It will be addressed in a future release.
