Sage 925VST Handheld VoIP Service Tester

The 925VST is a versatile handheld Voice Over Packet (VoP) service qualification tool, for both deployment and troubleshooting personnel who require a simple, reliable tester.

The 925VST makes and receives test calls, quickly profiling end-to-end performance and Telephony QoS across a network, qualifying ECHO, DELAY, Voice CLARITY (MOS) and packet loss. Calls can be made using a standard 2-Wire (POTS) or 4-Wire handset style interface enabling testing via an IP/Digital Phone or mobile or wireless handset. This product also includes other telephony over packet tests for services such as FAX. (T.30)

With the 925VST, field personnel place test calls to a Sage responder and perform automated packet voice tests to quickly Troubleshoot, Tune-up and underpin Service Level Agreements.
