The PSTN/Internet Interworking (PINT) working group will address connection arrangments through which Internet applications can request and enrich PSTN services. PINT will study the architecture and protocols needed to support services in which a user of the internet requests initiaton of a telephone call to a PSTN terminal. Note that the PINT working group will not study Internet telephony (that is the realm of AVT) or session control (MMUSIC).
