Techniques are disclosed for reducing the time for a wireless communication device originating a group communication, such as a push-to-talk call, to receive a call failure indication on a wireless communications system. In an embodiment, a group communications server receives a request to initiate a call with a target from an originator, and sends a corresponding message to a network node. If the call cannot be completed, the server receives from the network node an internet control message protocol (ICMP) message indicative of there being no connection between the network node and the target wireless communication device. In response to the message, the group communications server sends a status failure message to the originating wireless communication device. |
