A barcode-reading device can be configured to transmit a beacon message under certain circumstances in which the barcode-reading device may be lost, or may be likely to become lost, such as when a barcode-reading device becomes unintentionally disconnected from a base station. Intermediary systems can be configured to periodically listen for beacon messages from barcode-reading devices. When an intermediary system receives a beacon message, the intermediary system can determine whether the beacon message was sent by a barcode-reading device. If it was, the intermediary system can forward the beacon message (or at least some of the contents of the beacon message) to a remote server. In response to receiving a forwarded beacon message, a remote server can generate and send a notification message to one or more recipients. The notification message can also include information that indicates (or is in some way related to) the location of the barcode-reading device.

Systems, devices, and methods for preemptively resolving audio and video issues when multiple devices join the same conference from the same room. The systems, devices, and methods include automatically configuring conference features of the devices based on detected proximity with other devices participating in the same conference. A first device receives identifiers indicating a conference that a second device has joined from a particular location. The first device also receives a request to join the conference with the first device at the particular location, and configures the conference features in response to the request to join the conference that the second device has joined from the same particular location. Configuring the conference features includes modifying a conference feature on the first device to not conflict with the conference feature on the second device.
