Calculate Your Mean Opinion Score (MOS)

A Mean Opinion Score (MOS) is the value assigned to a hosted
PBX system assessing its data transmission and compression efficiency.
Running a MOS test can help users pinpoint present and future issues
with service stability and audio quality. MOS values range from 1 to 5 —
5 as the ideal. A typical hosted PBX sits in-and-around 3.5 to 4.2. By
calculating your system's measurement, you can map changes in voice
quality over time, which may help track and troubleshoot problematic
network components.

Digital and Analogue VoIP Gateway Options

VoIP gateways may be purchased in digital or analogue form. Analogue
gateways connect traditional telephones to a PBX system (or vice versa).
A digital VoIP gateway, however, connects a PBX system to digital voice
lines on the IP network. In terms of features, both analogue or digital
gateways are typically SIP, H.323 and MGCP compliant and offer G.711,
G.723.1, G.726, and G.729A codecs support. On top of this, many
interfaces provide echo cancellation, jitter buffer, VAD and CNG, as
well as various other capabilities like call routing.
