Method for managing a failure to establish a communication between a first and a second terminal

A device for managing communication between a calling terminal and a called terminal in the event that it is impossible to reach the called terminal using a first mode, the device comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium comprising instructions stored thereon which when executed by the at least one processor configure the device to perform acts comprising:
• receiving a message comprising an address of the called terminal and an indication according to which the communication is not able to be established,
• obtaining a welcome card comprising at least one item of information relating to reachability of a user of the called terminal based on identifiers associated with the calling terminal and with the called terminal, the at least one item of information comprising at least one alternative communication identifier associated with the user of the called terminal, which is selected and inserted into the welcome card by the device according to reachability criteria of the called terminal, and
• transmitting the obtained welcome card to the calling terminal in accordance with an instant messaging protocol, the welcome card being configured so as to make it possible to trigger communication using a mode different from the first mode.

A device for reception of a welcome card by a calling terminal in the event that it is impossible to reach a called terminal using a first mode, the device comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium comprising instructions stored thereon which when executed by the at least one processor configure the device to:
• transmit a message for establishing communication to the called terminal using the first mode,
• receive a welcome card in accordance with an instant messaging protocol, wherein the welcome card is generated by a server depending on an identifier of the called terminal and an identifier of the calling terminal, and the welcome card comprises at least one item of information relating to reachability of the called terminal, the at least one item of information comprising at least one alternative communication identifier associated with a user of the called terminal, which is selected and inserted into the welcome card by the server according to reachability criteria of the called terminal, the welcome card furthermore being configured so as to make it possible to trigger communication using a mode different from the first mode.

A non-transitory computer-readable recording medium on which there is recorded a computer program comprising instructions for executing a method when the instructions are executed by a processor of a communications server, the method being managing communication over a communication network between a calling terminal and a called terminal in the event that it is impossible to reach the called terminal in an attempt to establish communication using a first mode, wherein the instructions configure the communication server to:

• receive a message comprising an identifier associated with the called terminal and an indication according to which the communication is not able to be established,
• obtain a welcome card comprising at least one item of information relating to reachability of a user of the called terminal based on identifiers associated with the calling terminal and with the called terminal, the at least one item of information comprising at least one alternative communication identifier associated with the user of the called terminal, which is selected and inserted into the welcome card by the communication server according to reachability criteria of the called terminal, and
• transmit the obtained welcome card as a response message to the calling terminal in accordance with an instant messaging protocol, the response message being configured so as to make it possible to trigger communication using a mode different from the first mode.
