With the 925VST, installers place test calls to a Sage responder and perform automated packet voice tests to quickly profile end-to-end, network performance. The 925VST can place and receive test calls from a 2-Wire analog interface (POTS), or test from an IP Phone/Digital Phone 4-Wire analog handset interface.

Ensure QoS across the network, qualify ECHO, DELAY, MOS (clarity) and voice packet loss and much more!
