Feature Interaction in Internet Telephony
While Internet telephony aims to provide services at least equal to traditional telephony, the architecture of Internet telephony is sufficiently different to make it necessary to revisit the issue of feature interaction in this context. While many basic feature interaction problems remain the same, Internet telephony adds additional complications. Complications arise since functionality tends to be more distributed, users can program the behavior of end systems and signaling systems, the distinction between end systems and network equipment largely vanishes and the trust model implicit in the PSTN architecture no longer holds. On the other hand, Internet telephony makes end point addresses plentiful and its signaling makes it easy to specify in detail the desired network behavior. Many techniques for resolving interactions in the PSTN are no longer easily applied, but several new techniques, explicitness, authentication, and verification testing, become possible in the Internet enviro...
