Ritesh<br><br>ASR and ACD are not the major quality measures. QoS consists of a combination of jitter in ms, packet loss%, and delay in ms. Calling on a given system may have excellent ACD and ASR, but the calls may present conversation that is difficult to understand or annoying (high delay), causing users to migrate to another system even when 100% of calls connect. This can easily be the case as the route to the SBC or switch may be good, while the RTP or voice route may suffer from high packet loss, delay and jitter.<br>

<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">ASR: Average Successful rate - in essence what percentage of<br>
calls are going to be answered.<br>
ACD: Average Call Duration - the average duration of all calls.<br>
<br>
>From a business perspective - the higher the ASR the better<br>
because this means more calls actually connect. You can have<br>
a great quality route with high ACD - but if the ASR is only<br>
10% then it's pointless as 90% of calls will just get bounced.<br>
<br>
The higher the ACD the better because this typically indicates<br>
that the route is good quality (people talk longer). Another<br>
very important aspect to ACD is that high ACD also indicates<br>
less false answers, see below:<br>
<br>
FAS: False Answer Supervision - it's a fancy name to basically<br>
having the route operator rip you off and transmit an answered<br>
signal and start billing you as soon as it starts ringing, many<br>
times even if they don't actually deliver your calls anywhere.<br>
In this case ACD will be very low because calls aren't actually<br>
getting through - they're just billing you as-if they got through.<br>
<br>
That's all I could think of right now..<br>
