Abstract: In one embodiment, a headset receives, via a first service type of a wireless connection between a first telephony device and the headset, call-session identifier data of an active call maintained by the first telephony device. Media associated with the active call is communicated via a second service type of the wireless connection between the headset and the first telephony device. The headset sends to a second telephony device via a first service type of a wireless connection between the second telephony device and the headset, the call-session identifier data to enable the active call to be transferred from the first telephony device to the second telephony device based on the call-session identifier data. The headset receives from the second telephony device via a second service type of the wireless connection between the second telephony device and the headset, media for the active call.
