A shadow call refers to a covert or secret communication made between two or more individuals, often for the purpose of discussing sensitive or confidential information. This type of call is typically conducted in a discreet manner, away from the prying eyes and ears of others, and can involve the use of code words or encrypted technology. Shadow calls are commonly used in espionage, criminal activities, and clandestine operations, but can also occur in personal relationships where secrecy is desired. The term ‘shadow’ alludes to the hidden or obscured nature of these calls, which often take place in the shadows of society.
