What is self-accreditation?

Manufacturers with in-house VoLTE testing facilities, can self-accredit themselves under the GSMA Interoperability testing service. As part of this service, manufacturers test their devices in line with the test cases defined in GSMA PRD IR.25 and share successful test results with GSMA for cross-verification. GSMA then issues them a self-accreditation certificate that can be identified with an ‘-S’ suffix.
