Abstract
A multi-point to multi-point intercom system, formed by at least one intercom server and a plurality of intercom terminals, the intercom terminals registered as talking or listening intercom terminals in an intercom session table. The intercom server sends to listening intercom terminals some or all of the unmixed audio packets received by talking intercom terminals according to the intensity signal value found in the header of the unmixed audio packets.

A method performed at an intercom server of a multi-point to multi-point intercom system, comprising:
- a) receiving unmixed audio packets during a given period of time, each of the unmixed audio packets having audio data and a header, said header comprising an intercom terminal identifier corresponding to an intercom terminal of the intercom system and an intensity signal representative of an intensity of the audio data contained in the unmixed audio packet;
- b) upon reception of each of the unmixed audio packets of step a), identifying from an intercom session table at least one intercom session in which said intercom terminal of said packet is registered as a talker intercom terminal;
- c) identifying for each of said at least one intercom session identified in step b), listening intercom terminals according to the intercom session table;
- and
- d) for each of the listening intercom terminals identified in step c), sending those of said unmixed audio packets of step a) having the strongest intensity signals to said listening intercom terminal, up to a predetermined number of unmixed audio packets.
An intercom server of a multi-point to multi-point intercom system, comprising:
- an intercom session table linking registered intercom terminals and intercom sessions;
- means for receiving unmixed audio packets during a given period of time, each of the unmixed audio packets having audio data and a header, said header comprising an intercom terminal identifier corresponding to one of said registered intercom terminals of the intercom system and an intensity signal representative of an intensity of the audio data contained in the unmixed audio packet;
- first means for identifying from the intercom session table, upon reception of each of the unmixed audio packets received by the means for receiving, at least one of the intercom sessions in which the intercom terminal associated with said packet is registered as a talker intercom terminal;
- second means for identifying, for each of said at least one intercom session identified by the first means for identifying, intercom terminals registered as listening intercom terminals according to the intercom session table;
- and
- means for sending, for each of the listening intercom terminals identified by the second means for identifying, those of said unmixed audio packets received by the means for receiving having the strongest intensity signals to said listening intercom terminal, up to a predetermined number of unmixed audio packets.
