21 . A method implemented by a first device, the method comprising:

receiving a supervisor ID via a first wireless technology;

determining whether a device ID of a second device was received via a second wireless technology; and

transmitting a position communication request via the first wireless technology, the position communication request indicating the device ID, the supervisor ID, and a position ID of the first device, wherein audio of a telephone call is transmitted via the first wireless technology, at least in part based on the device ID.

22 . The method of claim 21 , further comprising:

transmitting a low-power request via the second wireless technology, wherein the first wireless technology is Bluetooth or WiFi, and the second wireless technology complies with a near-field communication (NFC) protocol.

23 . The method of claim 21 , further comprising:

establishing a position connection via the first wireless technology, at least in part based on the device ID of the second device.

24 . The method of claim 21 , further comprising:

receiving a position communication response via the first wireless technology, wherein the audio of the telephone call is transmitted at least in part based on a determination whether the position communication response was received.

25 . The method of claim 21 , further comprising:

receiving a device position request indicating an action via the first wireless technology, wherein the action is performed on the telephone call.

26 . The method of claim 21 , further comprising:

receiving a device position request indicating a numeric input via the first wireless technology, wherein a dual-tone multi-frequency (DTMF) tone is generated, at least in part based on the numeric input.

27 . The method of claim 21 , further comprising:

receiving a device position request indicating an audio signal, wherein the audio signal is applied to the telephone call.

28 . An apparatus comprising:

a network interface that receives a supervisor ID via a first wireless technology; and

a processor configured to determine whether a device ID of a device was received via a second wireless technology, wherein

the network interface transmits a position communication request via the first wireless technology, the position communication request indicating the device ID, the supervisor ID, and a position ID of the apparatus, and

audio of a telephone call is transmitted via the first wireless technology, at least in part based on the device ID.

29 . The apparatus of claim 28 , wherein the network interface transmits a low-power request via the second wireless technology, the first wireless technology is Bluetooth or WiFi, and the second wireless technology complies with a near-field communication (NFC) protocol.

30 . The apparatus of claim 28 , wherein the network interface establishes a position connection via the first wireless technology, at least in part based on the device ID of the device.

31 . The apparatus of claim 28 , wherein the network interface receives a position communication response via the first wireless technology, and the audio of the telephone call is transmitted at least in part based on a determination whether the position communication response was received.

32 . The apparatus of claim 28 , wherein the network interface receives a device position request indicating an action via the first wireless technology, and the action is performed on the telephone call.

33 . The apparatus of claim 28 , wherein the network interface receives a device position request indicating a numeric input via the first wireless technology, and a dual-tone multi-frequency (DTMF) tone is generated, at least in part based on the numeric input.

34 . The apparatus of claim 28 , wherein the network interface receives a device position request indicating an audio signal, and the audio signal is applied to the telephone call.

35 . A computer-readable medium comprising instructions that, when executed by a processor of a first device, perform operations including:

receiving a supervisor ID via a first wireless technology;

determining whether a device ID of a second device was received via a second wireless technology; and

transmitting a position communication request via the first wireless technology, the position communication request indicating the device ID, the supervisor ID, and a position ID of the first device, wherein

audio of a telephone call is transmitted via the first wireless technology, at least in part based on the device ID.

36 . The medium of claim 35 , the operations further comprising:

transmitting a low-power request via the second wireless technology, wherein the first wireless technology is Bluetooth or WiFi, and the second wireless technology complies with a near-field communication (NFC) protocol.

37 . The medium of claim 35 , the operations further comprising:

establishing a position connection via the first wireless technology, at least in part based on the device ID of the second device.

38 . The medium of claim 35 , the operations further comprising:

receiving a position communication response via the first wireless technology, wherein the audio of the telephone call is transmitted at least in part based on a determination whether the position communication response was received.

39 . The medium of claim 35 , the operations further comprising:

receiving a device position request indicating a numeric input via the first wireless technology, wherein a dual-tone multi-frequency (DTMF) tone is generated, at least in part based on the numeric input.

40 . The medium of claim 35 , the operations further comprising:

receiving a device position request indicating an audio signal, wherein the audio signal is applied to the telephone call.
