A Voice over Internet Protocol, VoIP, device for selecting a mode and communicating data based on the selected mode, the device comprising: at least one interface circuit, each interface circuit configured to monitor analog audio signals from one or more customer premise equipment device(s) during a communication to determine frequency components of the monitored analog audio signals from the corresponding customer premises equipment(s), and determine whether the frequency components are outside a first band of frequencies; a processor circuit coupled to the at least one interface circuit and configured to: assign, by a coordinated codec change between the VoIP device and a network or another VoIP device connected to the network, a first band mode for converting the analog audio signals to data packets during portions of the communication when none of the frequency components of the monitored analog audio signals as determined by the at least one interface circuit are outside the first band of frequencies, wherein each data packet comprises a header field and a data field; assign, by a coordinated codec change between the VoIP device and the network or the other VoIP device, a second band mode for the conversion during portions of the communication when any one or more of the frequency components of the monitored audio signals as determined by the at least one interface circuit are outside the first band of frequencies; and convert the analog audio signals to data packets by using the assigned one of the second and first band modes; and an output circuit coupled to the processor circuit and configured to receive the data packets from the processor circuit and to transmit the data packets through a communication channel to the network, wherein the second band mode for the conversion uses a larger bandwidth of the communication channel to the network than the first band mode for the conversion in transmitting the data packets through the communication channel. at least one interface circuit, each interface circuit configured to monitor analog audio signals from one or more customer premise equipment device(s) during a communication to determine frequency components of the monitored analog audio signals from the corresponding customer premises equipment(s), and determine whether the frequency components are outside a first band of frequencies; a processor circuit coupled to the at least one interface circuit and configured to: assign, by a coordinated codec change between the VoIP device and a network or another VoIP device connected to the network, a first band mode for converting the analog audio signals to data packets during portions of the communication when none of the frequency components of the monitored analog audio signals as determined by the at least one interface circuit are outside the first band of frequencies, wherein each data packet comprises a header field and a data field; assign, by a coordinated codec change between the VoIP device and the network or the other VoIP device, a second band mode for the conversion during portions of the communication when any one or more of the frequency components of the monitored audio signals as determined by the at least one interface circuit are outside the first band of frequencies; and convert the analog audio signals to data packets by using the assigned one of the second and first band modes; and assign, by a coordinated codec change between the VoIP device and a network or another VoIP device connected to the network, a first band mode for converting the analog audio signals to data packets during portions of the communication when none of the frequency components of the monitored analog audio signals as determined by the at least one interface circuit are outside the first band of frequencies, wherein each data packet comprises a header field and a data field; assign, by a coordinated codec change between the VoIP device and the network or the other VoIP device, a second band mode for the conversion during portions of the communication when any one or more of the frequency components of the monitored audio signals as determined by the at least one interface circuit are outside the first band of frequencies; and convert the analog audio signals to data packets by using the assigned one of the second and first band modes; and an output circuit coupled to the processor circuit and configured to receive the data packets from the processor circuit and to transmit the data packets through a communication channel to the network, wherein the second band mode for the conversion uses a larger bandwidth of the communication channel to the network than the first band mode for the conversion in transmitting the data packets through the communication channel.
