Telegate Voice Quality Reporting project is about catching CDR’s form Telegate PABX system CDR URL and extract information around call quality and present it in a simple format with ability to send email notifications and set alerts.
What is Mean Opinion Score?
In voice and video communication, quality usually dictates whether the experience is a good or bad one. Besides the qualitative description we hear, like 'quite good' or 'very bad', there is a numerical method of expressing voice and video quality. It is called Mean Opinion Score (MOS). MOS gives a numerical indication of the perceived quality of the media received after being transmitted and eventually compressed using codecs.
MOS is expressed in one number, from 1 to 5, 1 being the worst and 5 the best. MOS is quite subjective, as it is based figures that result from what is perceived by people during tests. However, there are software applications that measure MOS on networks, as we see below.
5 - Perfect. Like face-to-face conversation or radio reception.
4 - Fair. Imperfections can be perceived, but sound still clear.
3 - Annoying.
2 - Very annoying. Nearly impossible to communicate.
1 - Impossible to communicate
The values do not need to be whole numbers. Certain thresholds and limits are often expressed in decimal values from this MOS spectrum. For instance, a value of 4.0 to 4.5 is referred to as toll-quality and causes complete satisfaction. This is the normal value of PSTN and many VoIP services aim at it, often with success. Values dropping below 3.5 are termed unacceptable by many users.
Data we need:
I have attached [url removed, login to view] to this email which is data pushed from Telegate PABX - 'MOSCQ' column hold the data we want - We need to also need to collect the following:
Domain or PABX that made call
Extension inside that domain that made call
Date and Time of call
Direction of call
I would like to log into the application and see a horizontal bar chart of all domains and their MOS score - I want the ability to change from last 24 hour view, last 7 day view and last 30 day view.
If I select a domain I would like to see same data but sorted by Extensions for last 24 hour view, last 7 day view and last 30 day view.
Finally I would like to be able to configure a daily notification that would allow me to enter and admin email address for each domain and a report is sent with 24 hour view, last 7 day view and last 30 day view on 3 horizontal bar charts. I want to be able to edit this email template to add generic info on MOS scores and what is needed to improve them.
If there is an option to toggle between inbound, outbound or both call types it would be helpful.
That is it for stage 1 - Stage 2 could include ability to search by domain, extension or callID and possibly ability for customer logins.
