Abstract: A first device receives information indicating changed network conditions for a network supporting a call with a second device at a first audio bit rate, and provides, to the second device, a packet instructing use of a second audio bit rate. The first device starts a timer associated with receiving an indication that the second device is using the second audio bit rate, and receives, from the second device, a response packet at the first audio bit rate. The first device determines that the timer has expired, and provides, to the second device, additional packets instructing use of the second audio bit rate. The first device determines that a threshold quantity of additional packets have been provided to the second device, and re-negotiates the second audio bit rate with the second device. The first device continues the call with the second device at the second audio bit rate.
