Problem diagnosis in VoIP and IMS environments is often a complex and tedious job. Unlike generic protocol analyzers, Hammer Call Analyzer enables users to quickly visualize signaling and voice quality problems in VoIP networks. For example, the unique call list and multistage call flow display features walk engineers through the legs of a particular call.

In addition, Hammer Call Analyzer displays waveforms with full playback and media scores on any call you choose. These features allow engineers to isolate issues in the exchange of messages and media between various network devices and quickly understand the problem.
