Telephone Answering Machines in India must comply with safety and quality criteria by means of the BIS CRS (Compulsory Registration Scheme) certification. Under the direction of Bureau of Indian Standards (BIS), it adheres to IS 13252 (Part 1): 2010, which addresses safety criteria for electronic equipment and IT. Manufacturers have to apply with the necessary paperwork, test their goods in BIS-approved labs, and name an Authorized Indian Representative (AIR) should they be headquartered outside. Approved, products can feature the CRS mark. Before goods might be lawfully sold in India, this certification guarantees consumer safety, quality assurance, and regulatory compliance.
