By combining the strengths of active testing for even complex end-to-end transactions with best of breed passive VoIP monitoring, Hammer XMS provides a multi-dimensional view of test calls as well as live traffic propagating through the network.

For Active VoIP monitoring, Hammer XMS emulates IP or TDM end points and simulates both basic and featured voice and fax calls between active probes. Media and signaling quality metrics and test results are forwarded to a centralized server for correlation, analysis, reporting and storage.  Additionally, Hammer XMS passively probes, captures, correlates and analyzes signaling and media packets to assess the quality of every call — 24x7.  Using specialized packet processing hardware the system handles Gigabit wire rates.

The Hammer XMS Operations Server correlates active test results and passive metrics captured in multiple call records, manages a high performances call record database,  provides web accessible reports and feeds real time metrics to Network Management Systems.

IXCs, LECs, Cable MSOs and VoIP carriers rely on Hammer XMS to keep the networks running and their customers happy.
