WILMINGTON, Mass. -- Empirix Inc., the innovative provider of test and monitoring solutions for business-critical voice and network applications, today announced the Hammer Call Analyzerä, the industry's first VoIP application-aware analysis tool. Unlike more generic protocol analyzers, this new tool is designed specifically for debugging VoIP signaling problems. The analyzer's VoIP awareness manifests in its unique abilities to take actions based on values of protocol fields, to recognize individual call sessions and to display complete calls in a ladder diagram. This allows, for example, capturing packets based on a particular Megaco error code, even packets that come before such a trigger event. Having identified errors, one can quickly understand the bigger picture through the Call List, which presents bad messages within the context of a call session. Visualizing the cause of the problem is then easy with the multi-stage ladder diagram, displaying messages on each leg of a network, even with a mix of IP and TDM protocols. "Every aspect of the Hammer Call Analyzer has been designed to increase the users' productivity in fixing VoIP protocol problems and to reduce the protocol expertise required to solve signaling problems," said Phil Odence, director of business development for Empirix. "This focus has enabled us to 'wow' people who have been struggling with existing tools." Empirix Inc.
