A first group auditory data stream, from a transmitting subscriber device of a first group of subscriber devices or from a dispatch console and intended for the first group of subscriber devices, is received at a conference server. A second group auditory data stream from a transmitting subscriber device of a second group of subscriber devices is similarly received. The conference server determines a relative priority level of one of (i) the first group of subscriber devices relative to the second group of subscriber devices and (ii) the first group auditory data stream relative to the second group auditory data stream, and sets different relative signal gains of the first group auditory data stream and the second group auditory data stream as a function of the determined relative priority level. The two auditory data streams are then summed and forwarded towards the second group of subscriber devices.

The method of claim 1, wherein the first group of subscriber devices are members of a first talkgroup having a first talkgroup identifier, and wherein the second group of subscriber devices are members of a second talkgroup having a second talkgroup identifier different from the first talkgroup identifier. 3. The method of claim 2, wherein the first talkgroup operates on a first assigned traffic channel at a first trunked base station and the second talkgroup operates on a second assigned traffic channel at a second trunked base station. 4. The method of claim 1, wherein determining the relative priority level of one of (i) the first group of subscriber devices relative to the second group of subscriber devices and (ii) the first portion of the first group auditory data relative to the first portion of the second group auditory data comprises determining one of (i) that one of the first group auditory data stream and the second group auditory data stream includes emergency group auditory data and (ii) that the first group is a higher priority group than the second group or the second group is a higher priority group than the first group. 5.

The method of claim 1, wherein the first group of subscriber devices are operating on a first frequency at a first conventional base station, and the second group of subscriber devices are operating on a second frequency at a second conventional base station different from the first conventional base station. 8. The method of claim 1, further comprising refraining from summing the first portion of the second group auditory data into the first portion of the first group auditory data prior to forwarding, by the conferencing server, the first group auditory data to the first group of subscriber devices. 9. The method of claim 1, further comprising forwarding the summed group auditory data towards the first group of subscriber devices. 10. The method of claim 1, further comprising receiving, at the conferencing server, a first portion of a third group auditory data stream from a first transmitting subscriber device of a third group of subscriber devices; determining, by the conferencing server, relative priority levels of one of (i) the first and second groups of subscriber devices relative to the third group of subscriber devices and (ii) the first and second portions of the first and second group auditory data relative to the first portion of the third group auditory data; andsetting different relative signal gains of the first portion of the first, second, and third group auditory data as a function of the determined relative priority levels, and selectively summing the first portion of the third group auditory data stream with auditory data received for one or both of the first and second groups of subscriber devices in accordance with set priority levels. 11. The method of claim 10, further comprising forwarding, by the conferencing server, the first portion of the third group auditory data towards the third group of subscriber devices. 12. The method of claim 10, further comprising forwarding the second summed group auditory data towards the third group of subscriber devices. 13. The method of claim 1, further comprising: continuing to sum, by the conferencing server, further group auditory data generated for the first group of subscriber devices with further group auditory data generated by the second group of subscriber devices for a predetermined threshold period of time and as a function of the set different relative signal gains, and forwarding corresponding further summed group auditory data to the second group of subscriber devices for the predetermined threshold period of time; andafter the predetermined threshold period of time, refraining from summing further group auditory data generated for the second group of subscriber devices with further group auditory data generated for the first group of subscriber devices, and instead, forwarding subsequent group auditory data generated for the second group of subscriber devices to the second group of subscriber devices without summing subsequent auditory data generated for the first group of subscriber devices. 14. The method of claim 13, wherein the predetermined threshold period of time is between 5 and 300 seconds. 15. The method of claim 1, wherein summing, by the conferencing server, the first portion of the first group auditory data with the first portion of the second group auditory data to form summed group auditory data as a function of the different relative signal gains comprises summing the first portion of the first group auditory data with the first portion of the second group auditory data in the parametric domain. 16.
