Automated interoperability assessments based on iterative profling and emulation of SIP or T.38 fax-relay enabled devices

摘要

A system for and method of efficient interoperability assessment based on automated Behavioral Profiling and Emulation of SIP or T.38 Fax-relay Enabled Devices, for example, for profiling and emulating VoIP Phones such as SIP Phones, or T.38 Fax-relay devices such as Internet Aware Fax Terminals. The method includes a Multi-step/Multi-technology Iterative Profiling Stage that allows creating a Behavioral Profile based on the analysis of a plurality of traffic samples. Also, the method presents an efficient process of Device Emulation of an actual device to be used in interoperability assessment, including a Standard State Machine parameterized by a set of characteristics stored in the Behavioral Profile. The Emulation method can be used to duplicate one or more device behaviors exhibited either by different firmware revisions, software upgrades or by different OEM product models.
