ABSTRACT:
A method for analyzing ISVM signaling messages that includes copying, to a message file, messages being transmitted through a signaling link, extracting ISVM messages from the message file that meet at least one trouble criterion, storing the extracted messages in an error report file, and generating an error report from the error report file. The error report lists the extracted messages. Examples of the trouble criterion include messages referencing a designated directory number, messages reporting an error, messages having a signaling point code and a destination point code that are equal, query messages having no matching responses, and unit data service messages.
