A video calling service provides a mobile device user is provided the capability to transition from a voice call to a video call within a calling session in a voice over long term evolution (VoLTE). The example video calling service offers a seamless transition of a voice call to a video call in a simplified and efficient process. In an example, a graphical user interface is provided that allows a user to select controls to provide real-time stream of video of a live scene via a rear facing camera to another user during a video call. Other examples describe the merger of individual voice calls into a merged call with the individual calls grouped as a conference call. The examples provide simplified use of a mobile device to transition voice calls to a video call in a cellular carrier's mobile network.

Voice and video calling over long term evolution-based user interface

A first device may be unable to access a line hosting a call that has been placed on hold by a second device when the first device and second device are located remotely from each other. A server device may manage the status of the line to prevent the first device from accessing the line when the line is currently in control by the second device. When the first device and second device communicate via NFC, the line may be automatically released, so that the control of the line and of the call may be automatically transferred to the first device.
