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.
