<div>All the phones already have the latest firmware. They keep updating themselves automatically.</div>

<div>In my setup of Grandstream phones, all the computers of the network go through the phones, i.e. I am using the builtin phones as swithces. They all have 2 ethernet ports. Does this has to do anything with the voice quality, or do I need to change something in the phones' setup, like switching it from switch to router in basic settings? What is this NAT/Router setting anyways and how should it be setup?
