IP Telephony Interconnection: Service Requirements

This chapter does not make any assumption about the signaling protocol used to establish interprovider multimedia sessions nor the transport protocol used to exchange media traffic. These requirements are drawn with the objective of being valid for any type of Service Provider. From a solutions perspective, many technical implementations may be investigated and proposed to meet those requirements. This chapter is organized as follows: Section 10.2 identifies numerous requirements drawn from the perspective of an IP Telephony Service Provider. Section 10.3 is dedicated to customer's requirements. This section identifies a set of requirements drawn from the view-point of end users with regards to telephony services and their reachability scope.
