The answer-seizure ratio (ASR) is the percentage of telephone calls which are answered, a measure of network quality

telecommunications
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that fe ...

Definition
In telecommunication an attempted call is termed a ''seizure''; the answer-seizure ratio is defined as 100 times the ratio of answered calls, i.e. the number of seizures resulting in an ''answer'' signal, to the total number of seizures:

s and other call rejections by the telephone network count as call failures. However, the inclusion in the ASR accounting of some failed calls varies in practical applications. This makes the ASR highly dependent on end-user action. Low answer-seizure ratios may be caused by far-end switch congestion, not answering by called parties and busy destination circuits.
