a plurality of vehicle speakers, each vehicle speaker connected to a second node of the plurality of nodes;
a processor configured to receive data from the plurality of nodes via the audio bus;
a non-bus microphone, wherein the non-bus microphone is coupled to the processor;
a non-bus speaker, wherein the non-bus speaker is coupled to the processor;
a cellular module connected to the processor, wherein the cellular module is configured to connect a call initiated by the processor to a call recipient; and
