Abstract: A method for qualifying identity in a communication network upon initiation by caller terminal of a communication to a called terminal is described. The method is performed by the called terminal and includes receiving at least one identity of the calling terminal certified by a trusted third-party, as well as at least one non-certified identity of the calling terminal, and presenting the user of the called terminal with information representative of at least one of the identities of the calling terminal, accompanied by an indication representative of a qualification information indicating whether the at least one identity of the calling terminal is or is not certified by a trusted third party.

Abstract: Methods and devices for supervising a transfer of a call or of processing a call set up between first and second terminals in a communications network implementing an SIP type signaling protocol. The method is implemented after sending or receiving, as the case may be, a command to transfer the already-set up call to a call between the first terminal and a third terminal. The supervision method obtains an item of information relating to setting up the call between the first and third terminals and sends a command to resume the call between the first and second terminals as a function of whether at least one non-set up criterion is true. The processing method transmits information relating to setting up the call between the first and third terminals and sets up a call between the first and second terminals as a function of whether the resumption command is received.
