A method for enhanced bypass operation in a simulcast radio communication system, comprising: a) using a packet switched network to communicate simulcast communications from a control point system to a plurality of transmit/receive, hereinafter T/R sites (210 1, 210 2, 210 3) in a simulcasting communication session in which a common signal is broadcast wirelessly at the same frequency synchronously from a plurality of transmit/receive T/R sites (210 1, 210 2, 210 3) to a plurality of mobile radio units dispersed in a plurality of coverage areas respectively associated with each of the T/R sites (210 1, 210 2, 210 3), said T/R sites (210 1, 210 2, 210 3) responsive to a control point system controlling simulcast operations thereof; b) facilitating a dispatch communications by using the packet switched network to receive at the control point system dispatch data originating from a dispatch console and to communicate the dispatch data from the control point system to the plurality of T/R sites (210 1, 210 2, 210 3) participating in the simulcasting communication session; c) responsive to determination of a malfunction at a first T/R site (210 1) of said plurality of T/R sites (210 1, 210 2, 210 3), a) terminating participation of said first T/R site (210 1) in said simulcasting communication session, without disabling the simulcasting communication session in progress at a remainder of the plurality of T/R sites (210 2, 210 3), b) dynamically reconfiguring said first T/R site (210 1) to function in a multisite mode of operation in which said first T/R site (210 1) transmits data during a non-simulcast communication session established with a network switching center, hereinafter NSC, at times and frequencies which are different from a remainder of said T/R sites (210 2, 210 3) still participating in said simulcasting communication session; c) automatically registering said first T/R site as a multisite T/R communication site with the NSC in communication with said packet switched network, and d) selectively suspending communications of the dispatch data from the control point system to said first T/R site (210 1) and instead addressing said dispatch data from said NSC to the first T/R site (210 1) when said dispatch data is intended for mobile radio units in a coverage area of the first T/R site (210 1). a) using a packet switched network to communicate simulcast communications from a control point system to a plurality of transmit/receive, hereinafter T/R sites (210 1, 210 2, 210 3) in a simulcasting communication session in which a common signal is broadcast wirelessly at the same frequency synchronously from a plurality of transmit/receive T/R sites (210 1, 210 2, 210 3) to a plurality of mobile radio units dispersed in a plurality of coverage areas respectively associated with each of the T/R sites (210 1, 210 2, 210 3), said T/R sites (210 1, 210 2, 210 3) responsive to a control point system controlling simulcast operations thereof; b) facilitating a dispatch communications by using the packet switched network to receive at the control point system dispatch data originating from a dispatch console and to communicate the dispatch data from the control point system to the plurality of T/R sites (210 1, 210 2, 210 3) participating in the simulcasting communication session; c) responsive to determination of a malfunction at a first T/R site (210 1) of said plurality of T/R sites (210 1, 210 2, 210 3), a) terminating participation of said first T/R site (210 1) in said simulcasting communication session, without disabling the simulcasting communication session in progress at a remainder of the plurality of T/R sites (210 2, 210 3), b) dynamically reconfiguring said first T/R site (210 1) to function in a multisite mode of operation in which said first T/R site (210 1) transmits data during a non-simulcast communication session established with a network switching center, hereinafter NSC, at times and frequencies which are different from a remainder of said T/R sites (210 2, 210 3) still participating in said simulcasting communication session; c) automatically registering said first T/R site as a multisite T/R communication site with the NSC in communication with said packet switched network, and d) selectively suspending communications of the dispatch data from the control point system to said first T/R site (210 1) and instead addressing said dispatch data from said NSC to the first T/R site (210 1) when said dispatch data is intended for mobile radio units in a coverage area of the first T/R site (210 1). a) terminating participation of said first T/R site (210 1) in said simulcasting communication session, without disabling the simulcasting communication session in progress at a remainder of the plurality of T/R sites (210 2, 210 3), b) dynamically reconfiguring said first T/R site (210 1) to function in a multisite mode of operation in which said first T/R site (210 1) transmits data during a non-simulcast communication session established with a network switching center, hereinafter NSC, at times and frequencies which are different from a remainder of said T/R sites (210 2, 210 3) still participating in said simulcasting communication session; c) automatically registering said first T/R site as a multisite T/R communication site with the NSC in communication with said packet switched network, and d) selectively suspending communications of the dispatch data from the control point system to said first T/R site (210 1) and instead addressing said dispatch data from said NSC to the first T/R site (210 1) when said dispatch data is intended for mobile radio units in a coverage area of the first T/R site (210 1).
