To access a communication managed by a host communicating entity between participant communicating entities including the host communicating entity via a packet network (RP), a third-party communicating entity transmits a message (MI) to the host communicating entity, which message comprises at least one parameter (PM) associated with an identifier of at least one participant communicating entity. The third-party entity's access to a peer-to-peer communication established between the host entity and a participant entity may create a conference between the three entities. The third-party entity's access to a conference communication may cause a participant to be added to the existing conference. The host communicating entity applies a restrictive policy on mixing communication flows exchanged between the communicating entities as a function of the parameter and the identifier of the participant communicating entity associated with the parameter.

Establishment of a conference with a communication flow mixing policy

The present invention relates to a method for establishing telecommunication between at least a first and a second users within a telecommunication network comprising the following steps:

Method and equipments for establishing telecommunication

The invention concerns a method of setting up a call-back to a caller in a packet-based telecommunications network, and a terminal and a media server to execute this method. The call-back is initiated by a user receiving a media stream. The user sets up a packet-based connection to a media server and receives the media stream from the media server. After choosing by the user to call back the caller, the media server generates a cookie with data defining a state of the media stream and sends the cookie to the user. The user initiates the call-back to the caller independently of the media server. After termination of the call-back, the data defining the state of the media stream are sent to the media server and are used to resume the transmission of the media stream to the user from a state following the state defined by the data.

Method of setting up a call-back

The invention pertains to a method for retrieving at least one piece of information regarding a telephone communication between at least two telephone terminals () belonging to different users () via a communication server (), from at least one of the telephone terminals (). The invention further pertains to the corresponding communication server (). The inventive information retrieval method comprises the steps of the communication server detecting the closing of communication by one of the users () and the communication server () activating, for at least one of the users, an information retrieval service (). The retrieval service comprises, for each of the users (,) for which it is activated, the steps of selecting a form based on a criterion, submitting the form to the user (), and transmitting the completed form, along with said at least one piece of information, to a database ().

A method of playing a personalized clip offers a choice between a clip played locally by a device associated with a terminal of a calling party and a clip played remotely by a device associated with a terminal of a called party when the calling party's terminal is put on hold by the called party's terminal. It includes a step of interrogating the first terminal to determine if the clip must be played locally in the network to which the first terminal belongs or if the clip must be played remotely in the network to which the second terminal belongs.

The invention concerns a method of setting up a call-back () to a caller () in a packet-based telecommunications network, and a terminal and a media server () to execute this method. The call-back () is initiated by a user () receiving a media stream (). The user () sets up a packet-based connection to a media server () and receives the media stream () from the media server (). After choosing by the user () to call back the caller (), the media server () generates a cookie with data defining a state of the media stream () and sends the cookie to the user (). The user () initiates the call-back () to the caller () independently of the media server (). After termination of the call-back (), the data defining the state of the media stream () are sent to the media server () or an associated media server and are used to resume the transmission of the media stream () to the user () from a state following the state defined by the data.

The present invention relates to a method for improving communication confidentiality including the following steps:

Method and equipment for improving communication confidentiality

The invention concerns a method of providing an improved call forwarding service in a telecommunications network, and a network unit and a computer program product to execute this method. A call initiated by a caller () to a first callee () is consecutively forwarded, starting from the first callee (), to one or more further interlinked callees (), thereby forming a call forwarding chain (). A set of data is added to the call, the data comprising an identifier of each of the callees () involved in the call forwarding chain () and an address associated with a respective message memory () assigned to each of the callees () involved in the call forwarding chain (). When the call is forwarded to the message memory () assigned to a last callee () of the call forwarding chain (), the caller () is prompted to provide a message to be stored in one or more of the message memories (). From the set of data one or more of the addresses associated with the message memories () are retrieved. And the message received from the caller () is delivered to one or more of the message memories () by routing the message to the retrieved one or more addresses.

Method of providing an improved call forwarding service

To simplify the sending of signalling messages, a coupler of a switch is provided with an interpreter. The interpreter is capable of preparing the sending of a signalling message as soon as it receives an order of predetermined syntax. By acting in this way, the transmission of signalling messages is made transparent to the variety of protocols that might be used.

Switch provided with a signaling coupler, and a method of sending a signaling message

A method of routing a call in a private network, with overflow (alternate routing) onto another network, calculates various routes for setting up the call, with one or more overflows onto the other network, and chooses a route as a function of the overflow cost and the number of overflows. This minimizes the overflow cost and maximizes the use of private network resources. Taking the number of overflows into account limits the call setup time.

Routing calls with overflows in a private network

An interchange unit for a private telecommunications network executing partly in real time and partly in mixed mode, which interchange unit includes a half-link which has an interface using a protocol used by the interchange unit for connecting real time applications to the outside and an application-oriented interface to at least one mixed mode application. The invention enables dialog between a real time application and a mixed mode application without entailing modification of the real time applications.

Private network interchange unit application-oriented half-link

A multichannel dynamic telephone link provisionally sets up an internode medium connecting two nodes of a telephone network and including a plurality of channels each carrying a call between the two nodes. Time-delayed controllers associated with respective channels each assume a measurement state or an overshoot state or a latent state according to whether a call has been supported by the channel associated with the controller for a time less than an authorized duration or a call has been supported by the channel for a time at least equal to the authorized duration or no call has been supported by the channel, respectively. They clear down the internode medium when none of the time-delayed controllers is in its measurement state. One particular application is to private networks including a dynamic link via a public network.

Multichannel dynamic telephone link and method of operating it

To solve problems of standardization in signaling channels, which are becoming inextricable because of the proliferation of manufacturers and services, telephone configuration instructions are sent on data channels. Telephone central office receiving circuits include means for detecting in received messages an indication as to whether the received message must be interpreted as a modification instruction or as a normal data message.
