Human Factors
After pushback while taxiing for takeoff a loud alternating tone (on/off) was heard from our audio panel. We isolated it to the flight interphone and suspected it was coming from the wireless headset transmitter used for pushback (now out of range). We stopped our taxi and called maintenance; a mobile truck came out and removed the device from our nose strut. We resumed our taxi and then got a message from operations passed through ground control to call ops. We again stopped our taxi and called ops; the ground crew had realized their mistake and called to correct the problem we had addressed through maintenance.I believe procedures need to be in place to ensure the removal of the wireless transmitter prior to taxi. At a minimum flight crews need to ensure that the flight interphone needs to have the receive button remain on during taxi so the audio warning can be heard if the unit is still on the strut. I have no idea what damage to airplane and other equipment would occur if the gear were retracted and the wireless unit were still hanging from the nose strut.
B787 Captain reported they were cleared to taxi with the wireless headset transmitter still attached to the nose strut.
