I think a SIP to Public Switched Telephone Network(PSTN) gareway terminates both the signaling and media paths. SIP can be translated into, or interwork with, common PSTN protocols such as Integrated Services Digital Network(ISDN),ISDN User Part (ISUP), and other Circuit Associated Signaling (CAS) protocols

A SIP gateway is an application that interfaces a SIP network to a network utilizing another signaling protocol. In terms of the SIP protocol, a gateway is just a special type of user agent, where the user agent acts on behalf of another protocol rather than a human.

A PSTN gateway also converts the RTP media stream in the IP network into a standard telephony trunk or line.The conversion of signaling and media paths allows calling to and from the PSTN using SIP.
