Apparatus and method for selectively enabling an early push-to-talk (PTT) call set up request in a wireless communications network. When a user activates a directory application on a wireless device, the wireless device checks for network information received from a base station. If the network information indicates that the network is of a predetermined type and can advantageously set up the PTT call, the wireless device enables the early PTT call set up request by sending a data channel set up request to the base station. If the network information does not indicate the network is of the predetermined type, the wireless device does not send any data channel request to the base station until the user has actually initiates a PTT call.
