A method for forming and collaborating using a Telephony Collaboration Manager subscription system including an admin device and a guest device, the method comprising: activating a wireless feature on the admin device; determining, by the admin device, whether a new TCM group is to be created by the admin device; determining, by the admin device, whether to subscribe the guest device to an existing TCM group; determining, by the admin device, whether to join the guest device to a previously subscribed to TCM group; when the admin device determines that the admin device is to create the new TCM group, creating the new TCM group and assigning a name to the new TCM group; wherein if it is determined that the guest device is to subscribe to the existing TCM group, the method further comprises the guest device scanning for the existing TCM group and transmitting a subscription request requesting to be subscribed to the existing TCM group; and wherein if it is determined that the guest device has already joined a subscribed group, the method further comprises the guest device scanning for the previously subscribed to TCM group and transmitting a join request requesting to be registered with the previously subscribed to TCM group, wherein, when the guest device is subscribed to the existing TCM group or is joined to the previously subscribed to TCM group, the method further comprises: when a TCM request is received from a client device, being one of the admin device and the guest device, establishing a data connection between the client device and a master device, being another of the admin device and the guest device, and sending and/or receiving data to/from the client device, the method still further comprising: when an incoming call is received at the master device via a cellular network, broadcasting, from the master device, control signals to client devices of the TCM group; and transmitting, from the client device, signals to the master device, wherein the TCM subscription system connects the master device, having a phone number, with the client devices into the TCM group. activating a wireless feature on the admin device;
