Total telecom revenue lost to Short Stopping and Call Stretching attacks around the world amounted to $4 billion
in 2021. Total telecom-related losses in the same year amounted to $39.89
billion - a 28% increase on the year before. As the years pass, telecom fraud steals enormous amounts of revenue from operators worldwide and these two dubious telecom fraud schemes are key factors.
These two fraud schemes not only steal revenue, but they increase customer churn, create unresolvable dispute tickets and trigger country-wide blockages of entire numbering plans. Callers can't reach family and friends in these destinations and the terminating operators there lose major revenue due to lost traffic.
Local operators in high termination rate destinations like the Maldives, Algeria, the European Union and elsewhere are particularly vulnerable. But unfortunately, unlike spam calls
, the industry hasn't seen much of a response from regulators.
As Call Stretching and Short Stopping attacks become more prevalent in specific regions of the world, the prospects for preventing them become dimmer and dimmer. But call validation technology has changed this.
To understand the impact of Call Stretching
and Short Stopping
and how to stop it, we need first to understand the mechanism of how these fraud schemes work.
