SIGTRAN is not the only IETF Working Group protocol involved in defining new protocols to enable the integration of the PSTN with IP networks. PSTN and Internet Interworking (PINT) and Service in the PSTN/IN Requesting Internet Service (SPIRITS) are two IETF Working Group recommendations that address the need to interwork telephony services between the PSTN and the Internet. PINT deals with services originating in an IP network; SPIRITS deals with services originating from the PSTN.

In PINT, PSTN network services are triggered by IP requests. An SIP Java client embedded in a Java servlet on a web server launches requests to initiate voice calls on the PSTN. The current focus of this initiative is to allow web access to voice content and enable click-to-dial/fax services. In SPIRITS, IP network services are triggered by PSTN requests. SPIRITS is primarily concerned with Internet call-waiting, Internet caller-ID delivery, and Internet call-forwarding.12

Interworking between an H.323 architecture and SS7 could be similar to interworking between softswitch and SS7 (see Figure 9-11). The approach would be to use signaling gateways that terminate SS7 signaling. The SS7 application information would be carried by using SIGTRAN from the SS7 gateways to one or more H.323 gateways. The gateway itself can terminate SS7 links directly. In the H.323 architecture, the gateway itself contains a great deal of the application logic required for call setup, and the gateway is also the entity that performs the media conversion. By holding the application logic, it must send and receive

call control signaling information. As the gateway performs the media conversion, it should be placed at the edge of the IP network. Because the gateway is at the edge of the network, it is likely to be easier and more efficient for the gateway itself to terminate SS7 links from the PSTN directly. This architecture is shown in Figure 9-12.
Conclusion
A major misperception regarding VoIP networks is that they don t support SS7. As explored in detail in this chapter, SIGTRAN and other functions facilitate the transport of SS7 over IP networks. The advantages of this are many. Most importantly, the 3,500 features (assuming 3,500 features were truly necessary) of a Class 5 switch can be transported over a softswitched VoIP network. It also allows the interconnection of VoIP networks with the PSTN, thus making any telephone in the world reachable from either network. Interworking facilitates the migration from Time Division Multiplexing (TDM) to VoIP networks by coopting existing circuit-switched infrastructure into IP networks.

One objection many service providers have regarding Voice over IP (VoIP) and softswitch technologies is the perception that they do not duplicate the 3,500 features of a Class 5 switch. The first question many would have is, what are those features by name and what functions do they perform A consensus in the industry is that a residential customer may use a maximum of four or five features. A business customer may use upwards of a dozen features. Centrex 21 offers 21 of the most often used features. Private branch exchanges (PBXs) do not offer 3,500 features, as no such demand exists in the enterprise market. Subscribers access those features via their dual-tone multifrequency (DTMF) dial pads on their telephone handsets. Although in U.S. markets some regulatory agencies may require some features beyond Centrex 21, E911, and the Communications Assistance for Law Enforcement Act (CALEA), the race by Class 5 vendors to offer more and more features can be described in terms of Christensen s Innovator s Dilemma as technology over abundance. Softswitches that replace a Class 4 switch, for example, transmit features over the Internet Protocol (IP) network. Softswitches that replace a Class 5 switch utilize application and media servers that replicate the features found on a Class 5 switch. They potentially offer features not found on a Class 5 or not even possible with a Class 5 switch. These features are usually written in text-based languages using open standards. It is possible that, given the flexibility in creating new features, some softswitch solutions that replace Class 5 switches may eventually offer more than 3,500 features. If 3,500 features were a buying criteria for some service providers, then those same buyers will find softswitch very attractive. This chapter will provide an overview of how those features are delivered over a softswitch network. This chapter will also address the implication of new features in the market.
