Wait for retries to become due is not recommended as you could have agents waiting for a long time for a connect. In essence you could be calling a bunch of no answers and busies and never get a connect.
Stop Campaign – This is the recommended option. You can always restart the campaign at a later time and tray all the accounts that were not connects. (must have a “Y” in the fields “restart control option and Leave non connects eligible for recalls” in the campaign on the I-series.
Accelerate retries then stop campaign – Again this feature is not recommended as it could cause your agents to have long wait times. However, this feature is preferred over “Wait for retries to become due”.
