At least one subscriber unit (SU) () can register with a radio frequency (RF) site () for radio services. For each registered SU, a SU push to talk over cellular (PoC) client (-) can be activated/established. Communications can be mapped at the RF Site () between each registered SU () and a corresponding SU PoC client (-). Each SU PoC client (-) at the RF site () can be communicatively linked to a remotely located PoC server () using a PoC interface (). The SU PoC client (-) is a communication endpoint of the PoC server (). In one embodiment, a talkgroup PoC client (-) can be established at the RF site () that is linked to the PoC server (). Radio communications to and from the SU () can be routed through the SU PoC client (-) and/or the talkgroup PoC client (-) and through the PoC server ().
