VoIP static, interference and buzzing is usually associated with the introduction of a signal or voltage into the VoIP connection that is then converted into an annoying sound.

DUO IP address from your router
Modern implementations of DHCP will try and handout the same IP to the same MAC (unless the device hasn't been powered on for a while).
