The DoT by a Notification dated June 23, 2021 has issued revised guidelines (‘OSP Guidelines’) for Other Service Providers (‘OSPs’) superseding the existing guidelines. The OSP Guidelines aim to improve the ease of doing IT business in India, particularly for voice-based business process outsourcing (‘BPO’) services. The key changes introduced under the OSP Guidelines to the existing framework include inter alia: (a) removal of the distinction between international OSPs and domestic OSPs; (b) allowing the sharing of Electronic Private Automatic Branch Exchange (‘EPABX’) and ‘Public Land Mobile Phone Network’ infrastructure for office use; (c) permitting the interconnectivity of voice calls between two or more OSP Centres (whether of group or unrelated companies) for OSP operations and there being no restrictions on data interconnectivity between 2 (two) OSP centres; (d) OSPs being allowed to have EPABX at foreign locations subject to certain conditions; (e) entities that are not carrying voice based business process outsourcing services are not to be regulated under the OSP Guidelines. The no registration requirement for OSP centres in India and the security conditions provided in the existing guidelines continue to apply.
