Abstract: Systems and methods for overriding ad hoc talkgroup auto-dropping. One example method includes determining whether a contextual condition for a portable communications device meets a talkgroup formation criterion associated with an ad hoc talkgroup, and, in response to determining that the contextual condition meets the talkgroup formation criterion, sending a talkgroup identifier identifying the ad hoc talkgroup to the device. The method includes receiving a contextual condition update for the device and determining whether the update meets the talkgroup formation criterion. The method includes, in response to determining that the update does not meet the talkgroup formation criterion, sending an audio mute command based on the talkgroup identifier and a notification requesting an override action to the device. The method includes, when an override action indication is received from the device during a standby period, sending an audio unmute command based on the talkgroup identifier to the device.
