I am listening to it right now with a place wanting to deploy 10k
phones.. and no one has thought about a full reset yet.

We need to start a DHCP-VOIP drinking game...

take a slug every time you have to debug a 'DHCP problem' when the
phone is still set to use a static IP address...

take a slug when the phone is plugged into a switch/router that doesnt
have DHCP helper set up correctly...

take a slug when a phone is plugged into a LAN with a nearer DHCP
server that keeps giving the phone a public IP address..
