Method of controlling communications within a digital intercom system

A method of managing communications between a plurality of communication devices within a digital intercom system comprising:

• providing, for each communication device, an input table comprising:
• a plurality of rows each corresponding to a different one of the communication devices on the system;
• a plurality of columns each corresponding to a communication channel of a plurality of communication channels defining parameters dictating how the communication devices within the system will communicate;
• and a plurality of cells each defined by an associated row and an associated column of the input table, the cells containing volume control information for communication with the communication device corresponding to the associated row and over the communication channel corresponding to the associated column;
• providing, for each communication device, an output table comprising:
• a plurality of rows each corresponding to a different one of the communication devices on the system;
• a plurality of columns each corresponding to one of the communication channels;
• and a plurality of cells each defined by an associated row and associated column of the output table, the cells containing volume control information for communication with the communication device corresponding to the associated row and over the channel corresponding to the associated column;
• receiving, from a first communication device of the communication devices, an audio transfer request to send an audio signal to a second communication device of the communication devices;
• identifying a first cell from the cells of the input table of the first communication device, the first cell defined by a row corresponding to the second communication device and a column corresponding to an active channel of the communication channels of the first communication device;
• identifying a second cell from the cells of the output table of the second communication device, the second cell defined by a row corresponding to the second communication device and a column corresponding an active channel of the communication channels of the first communication device;
• comparing the volume control information of the first cell with the volume control information of the second cell;
• and
• modifying the audio signal based on the comparison of the volume control information of the first cell with the volume control information of the second cell.
