  • Method for setting up a conference call in telecommunications network using the SIP protocol
    Patent number: 8406404
    Abstract: This invention relates to a method for setting up a conference call in a telecommunications network using the SIP protocol to set up a communication between a first terminal (30) and a second terminal (32), call controllers (36ca30, 36ca32) relaying signals for this communication. According to the invention, such a method is characterized in that it comprises the following steps: the step to interrupt communication of the first terminal (30) with the second terminal (32) to set up a communication between this first terminal (30) and a conference bridge (38pc), the step to simulate the second terminal (32) maintaining its communication with the first terminal (30) using at least one of the call controllers (36ca30, 36ca32), and the step to simulate the second terminal (32) interrupting its communication with the first terminal (30) to set up a communication between this second terminal and the conference bridge (38pc).
