In systems and methods of talk group communication, a group PTT call is established between a originating wireless device and recipient wireless devices. A group identifier of the PTT call group is provided to the recipient wireless devices indicating that the PTT call involves a call group without indicating an identifier of originating wireless device. In an embodiment, when the group PTT call is terminated, a response call request is received based on the group PTT call from one of the plurality of recipients and a bilateral PTT call is established between the one of the plurality of recipients and the originating wireless device. In an embodiment, a response is received based on the group PTT call from one of the plurality of recipients, the group PTT call is terminated, and a bilateral PTT call is established between the one of the plurality of recipients and the originating wireless device.
