Patent ID: 7295577

Claim:
A method for generating a call flow record, comprising: detecting, on a first communication network, a first number of call signaling messages using a first communication protocol; detecting, on a second communication network, a second number of call signaling messages using a second communication protocol; and for a particular message in the first or second number of messages, the particular message being part of a particular call, extracting a first call identifier from the particular message; when a call reference exists for the first call identifier, adding the particular message to a call flow record for the particular call; when the call reference does not exist for the first call identifier, i) associating the first call identifier with a unique call reference for the particular call, ii) using the first call identifier to retrieve a second call identifier for the particular call, wherein the first and second call identifiers have formats defined by different ones of the first and second communication protocols, iii) associating the second call identifier with the unigue call reference, and iv) adding the particular message to the call flow record for the particular call; and updating a call flow record display based on the addition of the particular message to the call flow record for the particular call.
