摘要：Day by day, the number of companies interested in IP Telephony are increasing continuously. Session Initiation Protocol (SIP) is one of the most popular VOIP protocol that creates, modifies and terminates associations between Internet end systems, including conferences and point-to-point calls. This paper deals with the design and the implementation of a SIP debugger tool that can be used in the validation process of SIP devices. SIP debugger is a software tool that can be used to verify the compliance of Voice over Internet Protocol (VoIP) devices, such as soft phones to the SIP specifications. Different tools are available on the market to conduct a compliance and interoperability validation phase (Example: Wireshark). However, they often have features limited to packet capturing and decoding. The proposed tool, instead, can be inserted into an SIP network and is capable of observing and analyzing, in an automatic way, the communication steps. It operates by executing three subsequent phases. (1). Capturing and filtering the SIP messages (2). Analyzing them and (3). Comparing the message flow with a set of rules. When verification of some rules fails, an Output is reported by indicating the rule that failed and a list of possible causes.
