925VST

THE 925VST is a powerful handheld voice over packet (VoP) service qualification tool for field deployment and troubleshooting personnel who need a rapid and reliable installation tool.

No return customer visits or truck rolls!
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!
