Inter-switch voicemail analysis tool
First Claim
1. A method for analyzing inter-switch voicemail signaling messages comprising:
- copying, to a message file, transaction capability application part (TCAP) messages being transmitted through a signaling system 7 link of a public switched telephone network, wherein the TCAP messages are copied for a period of time, wherein the inter-switch voicemail signaling messages conform to a signaling protocol, and wherein the signaling protocol defines a maximum query response time;
identifying TCAP messages that reference a designated directory number;
copying the TCAP messages that reference the designated directory number into an error report file;
identifying TCAP messages that are unit data service messages;
copying the unit data service TCAP messages into the error report file;
identifying TCAP messages that are unit data messages;
defining a beginning portion of the period and an ending portion of the period, wherein the beginning portion and the ending portion are at least as long as the maximum query response time, wherein unit data TCAP messages that were copied to the message file during one of the beginning portion and the ending portion are buffer unit data TCAP messages, and wherein unit data TCAP messages that were not copied to the message file during one of the beginning portion and the ending portion are non-buffer unit data TCAP messages;
determining which of the non-buffer unit data TCAP messages are query messages;
copying the non-buffer unit data TCAP query messages into a table;
determining which of the non-buffer unit data TCAP messages are response messages;
deleting, from the table, non-buffer unit data TCAP query messages that have transaction identifiers equal to a transaction identifier of the non-buffer unit data TCAP response messages, thereby leaving remaining non-buffer unit data TCAP query messages in the table;
copying the remaining non-buffer unit data TCAP query messages into the error report file; and
generating an error report from the error report file.

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.
