Claim:
1. A method comprising: receiving, by a first receiving radio, a call including one of a header and an embedded control signaling including a call include bitmask (CIB); retrieving, by the first receiving radio, a call include list (CIL) that, for each bit position in the CIB, maps the bit position to one of a radio identifier, a talk group identifier, and a sub-CIL that includes a further listing of two or more of radio identifiers or talk group identifiers; determining, by the first receiving radio, that at least one bit position in the CIB is set to a value indicating that receiving radios associated with one or more radio identifiers mapped to the at least one bit position in the CIB via the CIL or associated with the one or more talk group identifiers mapped to the at least one bit position in the CIB via the CIL are to be included in the call; matching, by the first receiving radio, a radio identifier of the first receiving radio to the one or more radio identifiers mapped to the at least one bit position in the CIB via the CIL or matching a talk group to which the first receiving radio is subscribed to the one or more talk group identifiers mapped to the at least one bit position in the CIB via the CIL; and responsive to matching, by the first receiving radio, unmuting the call.
