Examples disclosed herein provide the ability for a computing device to configure one microphone at a time from physically colocated devices to remain active for participating in a teleconference. In one example method, the computing device determines whether a first device with a first microphone on the teleconference is physically colocated with respect to a second device with a second microphone on the teleconference. When the first and second devices are physically colocated with respect to each other, the computing device configures either the first or second microphone to remain active for participating in the teleconference while the other of the first or second microphone is to be muted.
