Researchers should note that a number of countries restrict the use of auto-diallers and other automated
dialling equipment including predictive diallers1
. Some countries2 may permit the use of such equipment
only if a person has given prior explicit consent (for example, as a member of an access panel) to be dialled
by automated dialling equipment. Where automated diallers are permitted and used, “abandoned or silent
calls”, where no live interviewer is immediately available, are not allowed.
