supports ITU-T P.564, G.107, ETSI TS101329-5 Annex E, RFC 3611 (RTCP-XR), RFC
6035 (SIP PUBLISH/NOTIFY). Most other competing products in industry
leverage a straight ITU-T G.107 E-model implementation which a) doesn’t
correlate well to true subjective opinion b) doesn’t support the 150+
codecs and their variants that VQmon does c) doesn’t typically provide
intra-call reports d) doesn’t handle wideband and super-wideband codec
measurements e) doesn’t support the analysis of video (e.g. conferencing or
IPTV) like VQmon can/does. It is extremely well regarded and enthusiastically
trusted by carriers (and large enterprise) worldwide, is the de facto industry
standard and has almost 200M units deployed to date.<o:p></o:p></span></font></p>

dual pronged approach, whereby they separately license the functionality on the

12.0pt'>Chiming in from the vendor perspective here... Telchemy manufactures a<br>
variety of embedded and non-embedded applications that are focused on<br>
measuring voice, video and other real-time service application performance.<br>
<br>
<br>
Our VQmon software is the de facto industry standard, is P.564 Class 1<br>
compliant and serves as the cornerstone for many industry products that<br>
feature MOS scoring and associated diagnostics, such as Adtran (mentioned by<br>
Jay below) as well as Edgewater, Polycom, Cisco and a wealth of network<br>
measurement / management tools and applications. A full list of vendors<br>
with products currently shipping can be found on our website -<br>
<a href="http://www.telchemy.com/partners.php" target="_blank">http://www.telchemy.com/partners.php</a>.<br>
<br>
There are typically three methods employed to measure/report on call/session<br>
quality:<br>
<br>
1. Measure live call quality @ the endpoint - typically achieved with an<br>
embedded performance analysis model (VQmon) baked into the device.<br>
Here's pointer to a joint solutions guide<br>
(<a
href="http://community.polycom.com/polycom/attachments/polycom/technology-partner%0d%0as/12/1/Telchemy-SQmediatorSolution%20Guide_01082013.pdf"
target="_blank">http://community.polycom.com/polycom/attachments/polycom/technology-partner<br>
s/12/1/Telchemy-SQmediatorSolution%20Guide_01082013.pdf</a>) that covers how we<br>
measure and report on EOL performance with Polycom, though there are a<br>
number of other IP endpoint vendors that support the rfc6035 distributed<br>
reporting model. The benefit of this approach is being able to account
for<br>
all impairments that affect your customer experience - but the downside is<br>
that sometimes you're measuring things (e.g. LAN performance) that you're<br>
not directly responsible for or have no control over. However - at the
end<br>
of the day - being able to understand what the net effect is of the total IP<br>
connection can certainly be of immense value.<br>
<br>
2. Measure call quality @ the WAN demarcation point - typically achieved<br>
with:<br>
a) a hardware probe (<a
href="http://www.telchemy.com/appliances.php" target="_blank">http://www.telchemy.com/appliances.php</a>)<br>
passively analyzing live customer traffic - providing full call setup,<br>
teardown and media quality metrics<br>
b) a software probe running on customer provided
hardware<br>
(<a href="http://www.telchemy.com/sqprobe.php" target="_blank">http://www.telchemy.com/sqprobe.php</a>)
passively analyzing live customer<br>
traffic - providing full call setup, teardown and media quality metrics<br>
c) an active test agent (<a
href="http://www.telchemy.com/dvqattest.php" target="_blank">http://www.telchemy.com/dvqattest.php</a>)<br>
generating synthetic voice, video and data transactions to create a profile<br>
of application performance and serve as a test head that can both probe the<br>
carrier network as well as the local LAN for real-time, proactive diagnostic<br>
purposes.<br>
<br>
Recalling that Kris was looking for a tool that enabled him to isolate WAN<br>
performance - it sounds as if our hardware/software probe line would make<br>
most sense for his application though collecting performance information<br>
from EOL devices certainly provides useful diagnostic information when one<br>
needs to provide empirical data as to which side of the WAN connection is<br>
causing the issue.<br>
<br>
Questions? Happy to help however I can.<br>

We use the Adtran TA900 series as a demarcation point, they are a very<br>
versatile SIP toolbox with huge feature set. They also do voice quality<br>
monitoring, can do packet capture, and can (but aren't required to)<br>
interface with Adtran's N-Command central server that can store<br>
historical data, back up configurations, etc.<br>
<br>
This isn't passive, but it provides very good monitoring in addition to<br>
PRI conversion, analog drops, SIP proxy, etc.<br>
