New from Koodo: Call Control (block robocalls)
Call Control helps reduce unwanted calls by prompting incoming callers to enter a randomly-generated number (0-9), which the caller must enter correctly before the call can be connected. Callers with no response (e.g. robo-dialers) or an incorrect response won’t be able to complete the call and will hear a standard Call Control message instead.
This feature also lets you manage preferences and maintain lists of Authorized and Blocked Callers.
