Abstract: A method is provided for managing a plurality of media flows to be reproduced by a calling device prior to the finalization of the establishment of a communication. The method is implemented by the calling device prior to the finalization of the communication. The method includes sending a request for the creation of the communication to at least one called device. For each media stream of the plurality of media streams, a first degree of priority associated with the media stream is searched for in a message received in response to the request for creation of the communication. A media stream to be played is selected from the plurality of media streams, according to second degrees of priority associated with the media streams of the plurality of media streams, the second degrees of priority obtained according to the result of the search.

Abstract: Method of routing in a telecommunications network an SIP message intended to be routed through intermediate entities constituting nodes of a signaling path. According to the invention, said method comprises a step of bypassing an intermediate entity able to be bypassed if unavailable. Application to the IMS architecture.

Abstract: The invention concerns a method for connection to IP communication entities (Ex,pu,, Ey,pu) via a residential gateway (PZ). It consists in registering (A) the public identity (pu) of each connected terminal associated with the network address (z) of the residential gateway, so that any message should be addressed to said residential gateway (Pz) and in transferring (B) said message to all the IP communication entities connected to the residential gateway (Pz), thus permitting each of the latter to filter (C) the message and to determine whether the message is addressed to a public identity which is assigned thereto. The invention is applicable to IP terminals managed in accordance with SIP or H323 protocol.

Abstract: Devices, systems, and methods for sending and processing session initiation protocol (SIP) responses are disclosed. According to one aspect, a method for sending an SIP response through a first telecommunications network node is described. The method includes receiving, by means of the first node, a SIP request sent by means of a second node of the network. The method includes detecting an event that interferes with processing of said request by means of the first node. The method further includes sending, to the second node, a SIP response notifying said interference. The method also includes, before the sending step, activating, within the SIP response, a parameter that allows the request to be rerouted, said parameter being configurable by means of the second node.

Abstract: This method is for managing flows between a first appliance and at least one second appliance, these appliances being designed to operate according to the so-called SIP protocol on a telecommunications network, wherein, the second appliance being preferably registered with the first appliance. The method comprises upon reception of a notifying message related to the loading state of said first appliance sent according to the SIP protocol, the implementing a procedure for spacing communications sent from the second appliance to said first appliance as a function of the loading state of the latter.

Abstract: This method of managing public identities in an information transmission network (11) of internet type implementing an SIP protocol for establishing data transmission links between said network and equipment for managing a group public identity (10) connected to this network is characterized in that it comprises: —a prior step of recording a group common public identity representative of at least one group of several individual public identities managed by said management equipment (10), at a public identities record management server (12); —a step of verifying a request to establish an incoming call, said request containing a numbering sequence, intended to verify whether said sequence corresponds to a recorded group public identity; and a step of sending said request to a contact address corresponding to the recorded group public identity.
