Abstract
To verify the identity of the sender of a telephone call over an Internet network, there is inserted into a field of a call set-up request frame an encrypted control code containing parameters relating to the identity of a telecommunications terminal from which the telephone call is sent. A remote call management server decrypts the control code. At least one parameter extracted from the decrypted control code is compared with corresponding information stored in a database hosted in the server, and the call is set up as a function of the result of the comparison.
