Abstract
Public Switched Telephone Network (PSTN) services such as 800-number
routing (freephone), time-and-day routing, credit-card calling, and
virtual private network (mapping a private network number into a
public number) are realized by the Intelligent Network (IN). This
document addresses means to support existing IN services from Session
Initiation Protocol (SIP) endpoints for an IP-host-to-phone call. The
call request is originated on a SIP endpoint, but the services to the
call are provided by the data and procedures resident in the PSTN/IN.
To provide IN services in a transparent manner to SIP endpoints, this
document describes the mechanism for interworking SIP and Intelligent
Network Application Part (INAP). This memo provides information for
the Internet community.
