摘要: An apparatus and method achieve a level of telephony application functionality commensurate with TDM (Time Division Multiplex) device interfaces used in legacy PSTN (Public Switched Telephone Network) voice facsimile applications. The rely upon the architectural model embraced by VOP (Voice Over Packet) carrier network standards, include elements protocol framework. build SIP to incorporate essential functions previously only available using infrastructure. service interface incorporates mechanisms for both call control media operations. Together, transition services data-centric exploiting switching digital signal processing capacity software switch controller gateway defined as core
