The GSMA launched the RCS Universal Profile v3.1 update, enhancing audio messaging with the xHE-AAC codec for clearer voice notes. This builds on March's v3.0 update, which introduced end-to-end encryption. The v3.1 update also improves RCS service reliability, particularly in areas with weak coverage. These improvements stem from a collaborative effort to boost media quality, service flexibility, and global scalability.
