scope:

This Recommendation provides the general framework for countering IP multimedia spam. The framework can be applied to IP-based multimedia applications such as IP telephony, instant messaging, multimedia conference, etc. The framework includes four anti-spam functions, i.e., core anti-spam functions (CASF), recipient-side anti-spam functions (RASF), sender-side anti-spam functions (SASF), and spam recipient functions (SRF). It describes the functionalities and the interfaces of each function for countering IP multimedia spam. Technical means for the implementation of the framework are outside the scope of this Recommendation.

Compliance with all relevant laws and regulations should be considered before adopting the antispam methods described in this Recommendation.
