| MySpeed Server VoIP simulates a VoIP connection and measures the key factors affecting connection quality. The information below is provided in the VoIP test results. | |

| VoIP TEST | |
| VoIP Simulation Test • All VoIP editions |
UDP VoIP traffic is simulated between your server and the browser client, diagnostic tests are performed to measure the critical factors that impact VoIP connection quality. |
| MOS Score • All VoIP editions |
MOS is a numeric measure of the sound quality
of a communication connection. Although the score
is subjective it provides a widely-used method to
rate the quality of voice communication. The score is normally between 1 and 5 with 5 being the best. In MySpeed VoIP, a VoIP simulation that drops below 3.5 is considered poor quality, a measure of 4.2-4.5 is considered good quality. |
| Jitter • All VoIP editions |
Jitter a plays a major role in the quality of a
VoIP call. Jitter is the variation in time between
packets sent and packets arriving caused by network
difficulties such as route changes, congestion, packet
loss, traffic regulators, etc. VoIP works by sending
voice data as a stream of packets from source to
destination. These packets can take a varying amount
of time to reach the destination and invariably do
not arrive in the order in which they were sent.
If packets are lost or arrive too late to be put
back in the correct order, it adversely affects the
sound quality. MySpeed VoIP measures the amount of jitter during the VoIP test and reports the corresponding level of expected sound quality. |
| Packet Loss • All VoIP editions |
Packet loss plays a key role in the quality of
VoIP connections, as high packet loss causes some
of the voice data not to arrive to the recipient.
Packet loss occurs when voice packets are discarded
by the jitter buffer, or dropped by network routers/switches
due to high congestion. MySpeed VoIP measures the percentage of packet loss and reports the associated level of sound quality. For more accurate results Packet Loss is measured in one direction only, which is normally not possible using traditional methods such as ping, where routing can affect the reply. |
| TraceRoute Analysis • VoIP NOC, Support Editions |
The NOC
Edition includes RTAs (remote test agents)
and Support
Edition RSAs (remote support agents) can be
deployed to multiple remote systems for automated
VoIP and bandwidth testing. The RTAs and RSAa can
run traceroute tests from the remote system to
the MySpeed Server, and report the diagnostic information
to the central performance
database. Internet connections involve multiple networks and device, and the routing path between 2 points can change frequently, complicating the process of pinpointing connectivity problems. Traceoute analysis is extremely useful in identifying the network device or segment that is causing poor performance. |
| Advanced Statistics • VoIP Professional, NOC, Support Editions |
The Advanced Statistics report tab provides a summary
of the above test results for each VoIP simulation
test, along with more detailed statistics including:• Jitter: from server to client |
| NEW! VoIP
Quality Graph • VoIP Professional, NOC, Support Editions |
The VoIP Quality Graph shows the variance of UDP jitter and packet loss during the test. For good sound quality variance of jitter and number of lost packets must be kept to a minimum. |
