Systems, methods, and devices of the various embodiments enable dynamically creating and joining group communication sessions without (i.e., "free of") operator-controlled or operator-assisted provisioning. By encoding group call provisioning information in a bar code, such as a Quick Response Code ("QR code"), that participants can scan using their mobile communication devices (e.g., smart phones), a group call may be created and provisioned on communication devices. The QR code encodes the information needed to initiate and/or join a group communication session maintained by a group communication server. |
