Understanding Average Call Duration (ACD) 📱

The Average Call Duration (ACD) is calculated by taking the sum of billable seconds (billsec) of answered calls and dividing it by the number of these answered calls <br />VoIP providers mostly offer Least Cost Routing (LCR) to ensure higher quality of service. <br />LCR efficiently and successfully transfers your calls at a reasonable cost. It saves time and <br />effort for routing international calls by using most cost effective method for transferring traffic. <br />Thus improving the overall quality of the service provided.In order to route a call effectively, certain issues should be considered and improved <br />accordingly such as: <br />Average Call Duration (ACD) <br />It is the total amount of time taken by the call. In case of lower ACD, it is expected <br />that the quality of the connection is not good enough for the subscriber to continue <br />the call. <br />Post Dial Delay (PDD) <br />On dialing phone number, either there is a ring or busy tone that tells us that whether <br />the called party is available or not. The time elapsed between dialing a number and <br />hearing a tone is referred to as Post Dial Delay (PDD). In case of higher PDD, it is <br />expected that there is no dial tone for the subscriber to initiate a call. <br />Answer-Seize Ratio (ASR) <br />It is the ratio between the successful calls and the attempted calls that cannot be <br />answered for any reason. In case of lower ASR, it is expected that the route provided <br />to the call is choked-up for the subscribers to make phone calls.
