Anonymous call rejection meaning

A network or handset feature that automatically blocks incoming calls where the caller has deliberately withheld their number (calling line identification, CLI). In practice, organisations enable anonymous call rejection (also called anonymous caller rejection or withheld number rejection) to reduce nuisance or malicious calls and to manage contact policies. The expression is descriptive rather than a defined statutory term. However, the underlying functionality is required in law: UK Privacy and Electronic Communications Regulations 2003 (PECR) and Ireland’s 2011 ePrivacy Regulations (implementing Directive 2002/58/EC) require providers to ensure subscribers can, by a simple and free procedure, reject incoming calls where the caller has prevented CLI presentation. Ofcom (UK) and ComReg (Ireland) regulate implementation alongside CLI rules. Key features: - Operates at network or device level and typically plays an automated message to the caller. - Targets calls where CLI is deliberately withheld; it does not generally block calls where CLI is unavailable for technical reasons or where invalid CLI is presented. - Available to fixed and mobile subscribers; provider terms, availability and default settings vary. Usage and effect are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, though product names and activation processes may differ by provider.
