Patent ID: 7630319

Claim:
A method of decoding tokenized Session Initiated Protocol, the method comprising: collecting, at a server, a plurality of tokenized Session Initiated Protocol packets from calls that are not successfully completed; receiving, at the server, a first tokenized Session Initiated Protocol packet from the plurality of tokenized Session Initiated Protocol packets; extracting, at the server, a string table from a user datagram payload in the first tokenized Session Initiated Protocol packet; decoding, at the server, the string table from the user datagram payload; creating, at the server, an index for the string table, wherein the index includes an IP address for a server that generated the first tokenized Session Initiated Protocol packet; storing, at the server, the index for the string table; accessing, at the server, a decoding table; determining, at the server, a corresponding entry in the decoding table for each token in the first tokenized Session Initiated Protocol packet; executing, at the server, the corresponding entry for the each token to decode the first tokenized Session Initiated Protocol packet; and displaying, through a user interface communicatively coupled to the server, the decoded first tokenized Session Initiated Protocol packet on a display device as a Session Initiated Protocol message, thereby allowing an evaluation of the Session Initiated Protocol message to determine what caused a call to not be successfully completed.
